Development teams are under increasing pressure to ship software faster, even as the environments they rely on grow more complex. However, modern development has only become harder to provision and maintain with AI-assisted development, cross-platform toolchains, tighter security demands and specialized compute requirements. As a result, developers still spend too much time configuring machines, troubleshooting environment drift, and waiting for access instead of building and shipping software. Windows 365 provides secure, flexible Cloud PCs that can complement local development and give teams an easier path from access to first commit. Developers can select an environment suited to each workload while IT applies consistent identity, security, management and governance.

Five ways Windows 365 supports modern development

1. Give developers a ready-to-code, customizable environment

A ready-to-code Windows 11 developer configuration provides developers with a prepared environment from day one. Autopilot device preparation can install required applications and scripts before first sign-in, while Azure Compute Gallery integration supports standardized custom images. Planned VM customization will provide additional flexibility to configure project-specific SDKs, tools, scripts, and dependencies within enterprise guardrails.

2. Scale compute and run local AI directly on the Cloud PC

Cloud PC configurations up to 32 vCPU and GPU-enabled options give teams the right compute for memory-intensive development, graphics, AI, data and visualization workloads. Select local language models can run directly on appropriately sized Cloud PCs, providing more predictable costs while preserving access to hosted models when greater scale or performance is required. https://www.youtube.com/watch?v=M-WDKwkGuZc See how a ready-to-code Windows 365 Cloud PC uses Foundry Local and local language models to build and run an AI meeting-summary app without consuming cloud tokens. 3. Contain agent activity during development Developers increasingly use coding and autonomous agents to generate code, execute tasks and maintain long-running workflows. With Windows 365 support for Microsoft Execution Containers (MXC) becoming generally available in the coming months, customers will be able to run supported agent workloads, from coding agents such as GitHub Copilot CLI to autonomous agents such as OpenClaw on managed Cloud PCs. Process and session isolation help contain agent activity, while familiar enterprise security and governance controls allow organizations to manage these workloads with confidence.

4. Build and run enterprise agents securely

AI agent builders have different needs. As agents move from development into sustained enterprise workflows, they may require dedicated environments that operate independently from users’ devices. Windows 365 for Agents provides Microsoft Entra-joined, Microsoft Intune-managed, and policy-enforced Cloud PCs where agents can perform computer-use tasks across browsers, desktop applications, and legacy systems. New preview capabilities extend secure access to on-premises applications and help IT manage agent pools at scale.Companies such as Login VSI, WorkspaceDNA, and Simular are already building AI agents that can run on Windows 365 for Agents.

5. Protect sensitive development work

Organizations need to give developers flexibility without exposing source code or confidential data. Windows 365 works with Microsoft Entra, Microsoft Intune, and Microsoft security capabilities to apply consistent identity, access, compliance and endpoint controls. For example, context-based redirection, now in preview can restrict clipboard, drive, printer or USB redirection based on security conditions, while output protection helps safeguard on-screen information.

Why modern development needs an environment that responds to change

As development workflows evolve in the era of AI, developers need different environments based on workloads. Local devices remain essential for developers when direct hardware access, offline work, or specialized local performance matters. Pairing the latest in hardware innovation with software optimized for development helps developers build breakthrough experiences. Project Zenith offers a ready-to-code distraction-free Windows experience on developer-class devices with 64+ GB unified memory and 250+ GB/s memory bandwidth, so developers can get started. And cloud-based environments can complement local development when continuity across devices, workload isolation, flexible compute, or secure access creates a better outcome.  Developers should be able to choose the environment best suited to their work while maintaining a consistent, trusted development experience. A developer may move between coding, compute-intensive builds and testing, AI-augmented application development, and work in a secure customer environment. Each workload benefits from an environment optimized for its specific requirements.  

Windows 365 brings the right environment to developers

A modern developer environment should allow developers to begin coding on day one, support customization for specific projects and provide secure governance without limiting developer flexibility. Windows 365 brings these capabilities together in a personalized Cloud PC that developers can access through the Windows App or a browser, while their applications, code, settings and project state remain securely managed in the Microsoft Cloud.  With Windows 365, developers can start with a Windows 11 developer configuration featuring familiar tools such as Visual Studio Code, Git, GitHub Copilot CLI, Python, Node.js and Windows Subsystem for Linux with Ubuntu. Meanwhile, platform engineering and IT teams can standardize environments with reusable images and automated preparation while centrally managing identity, security, policy, monitoring, and lifecycle controls.  The result is more than a desktop in the cloud: it is a faster path from access to first commit. Customers are already seeing this balance of developer flexibility and enterprise control in practice: London Stock Exchange Group increases developer productivity with Windows 365. “Windows 365 gives us the ability to provide different types of performance and development environments plus access to GitHub Copilot, where we’ve seen an increase in developer productivity and efficiency.” says Sandra Lee, Group Chief Information Security Officer, LSEG.Siemens uses Windows 365 for scenarios that include developers who need specialized digital tools, as well as employees requiring temporary access. “In all these cases, we need a trustworthy device and a verified identity in our IT landscape—even if the access is only intended to be temporary,” says Hendrik Harder, Global Service Owner Virtual Client at Siemens. ABN AMRO transforms the workplace for 3,500 offshore developers with Windows 365. Developers reported smoother performance, faster onboarding and more productivity, while IT teams benefited from simplified operations and scalability. “The first time I used Windows 365, I thought I was using my own laptop—the performance was that smooth,” says Peter Witmond, Product Owner Virtual Workplace at ABN AMRO.

Advancing developer experiences with Windows 365 on a unified platform 

Microsoft is bringing cloud development environments together on a single platform. With the retirement of Microsoft Dev Box, Windows 365 becomes Microsoft's strategic platform for virtualized developer environments, AI and agent workloads, and the broader workforce. While existing Dev Box customers can continue using their deployments according to the official service timeline, Windows 365 offers a broader, unified foundation for developers and organizations moving forward. Dev Box proved what developers need: environments that combine developer flexibility with enterprise control. Windows 365 carries these promises forward and extends them across developers, information workers, AI builders and agents through a shared foundation for identity, security, management, and access models. That shared foundation is what makes the next generation of developer Cloud PCs possible.​‌ 

Turning workload choice into a modern developer workflow 

With Windows 365, organizations can start with a ready-to-code environment, match compute to each workload, contain agent activity during development, provide dedicated environments for enterprise agents and apply consistent controls to protect sensitive work. Start with a scenario where setup delays, hardware constraints or security requirements slow delivery, and measure improvements in onboarding, time to first commit, support requests, or build performance. Explore Windows 365 developer resources and review the official Microsoft Dev Box guidance.

• Experimental (26H1): Build 28120.2912
• Experimental (Future Platforms): Build 29661.1000

Notable new features:

[Cross-device resume improvements]

Release channel: Experimental We're making it easier to continue where you left off on your PC. When you resume a webpage from your phone and the phone's browser isn't installed on your PC, the Resume hovercard now gives you two options: open the page directly in your PC's default browser or install the phone's browser for a native experience. This update helps you continue your work immediately without requiring an app installation first. [caption id="attachment_179156" align="aligncenter" width="864"] The Resume hovercard provides an option to open the webpage in the PC's default browser.[/caption] [caption id="attachment_179157" align="aligncenter" width="684"] The Resume hovercard provides an option to install the originating phone browser.[/caption]

Math is at the heart of STEM education and learning, and this update helps students and professionals independently read, understand, and explore equations, formulas, and scientific notations with confidence. Read more in release notes link above. [caption id="attachment_179158" align="aligncenter" width="2303"] Screenshot of Windows settings page with Narrator Math reading settings page open[/caption]

[Magnifier]

Release channel: Experimental Magnifier now understands each of your displays

• Every screen keeps its own view, at its own zoom. In earlier versions of Magnifier, zooming in stretched a single magnified view across all of your displays, so one screen's zoom followed you everywhere and screen edges blurred together. With this update, each monitor's boundary is respected, and each monitor can hold its own zoom percentage. Your writing screen can sit at 300% while your reference screen stays at 150%, and the magnified view no longer spills from one display into the next. This matters because different tasks, and different screen resolutions, often call for different levels of magnification to stay comfortable to read. Read more in release notes link above.

The latest Windows Family Safety improvements are part of a broader effort to create safer, age-appropriate digital experiences for kids and families. As we’ve recently outlined, Microsoft Family has been on a focused journey to raise the quality of the everyday offering that parents and kids rely on — and that journey started by listening to you. We gathered feedback from families and let it guide our priorities, month after month.   The result is a steady stream of meaningful fixes we continue to iterate on:  

• Parental approvals for offerings like screen-time extensions, app access, and purchases now happen faster, so kids aren’t left waiting and parents stay in control.
• We restored clear visibility into web and app activity so parents can trust what they see in their reports.
• Made spending more transparent, with wallet balances.
• We also gave adults in a family more control over their own experience, making it far easier to add, manage, or leave a family group 

We know these areas have presented pain points, and while we've made progress, we know some of you may still run into issues. We're continuing to improve and will continue to listen to your feedback as we improve the experience.  

Parental control: Faster and reliable approval flows 

Parents and children may have experienced inconsistent and noticeable delays while approving children requests such as app access, screen time extensions, and purchase approvals. During these delays, children are unable to access the requested content or continue their activities, while parents are left uncertain whether their approval has been received and applied.  Parental approvals for app access, screen time extensions, and purchases now happen faster than before, reducing wait times and frustration for parents and kids alike.  

Activity reporting: full app coverage 

Some parents noticed that certain apps were missing from activity reports, making it difficult to fully understand how their child was using their device. Activity reporting now includes broader app coverage across all applications used on a child's PC, providing a more complete and trustworthy view. Additional improvements to usage time accuracy are also on the way.  Both parent and children will have the broader view of apps used and time spend.  

Family funding balance after top-up 

Family funding balance was not reflecting proper updated balance but now this issue has been addressed, and parents can now easily manage the funds for their children.   Each of these improvements came from a real family experience — from issues parents told us mattered most: speed, accuracy, control, transparency, and peace of mind.  This is the compounding effect of a team that treats every piece of customer feedback as a commitment to do better. Thank you to every parent who shared their voice; you’ve shaped this product, and we’re just getting started.  All of the above fixes are available in the latest versions of the Family Safety mobile app both iOS and Android are available. You can also access Family Safety on the web by visiting: https://account.microsoft.com/family/  

What’s next 

We also know the journey is not over. While we have made important progress, some families may still run into issues, and we want to hear about them.  If something is not working the way you expect, please reach out to us at familysafetyfeedback@microsoft.com. That inbox is more than a contact point — it is an open invitation from our team to yours. Your feedback helps us understand what families are facing today so we can fix issues at the earliest and keep improving.  Thank you to every parent who shared their voice. You have shaped this product, and you will continue to shape what comes next.  We have been listening. We have been fixing. And we will keep going.

Our children and teens are growing up in a digital world where apps, games, and AI-powered tools are part of how they learn, play, create, and connect. For parents and educators, that brings both opportunity and responsibility: digital experiences should help young people explore with confidence while supporting their wellbeing, building healthy habits, respecting their privacy, and providing protections that are appropriate for their age.  At Microsoft, we believe safety should be easier for families to understand and easier for developers to build into experiences for children to use. On Windows, that starts with the account. Microsoft account is a trusted foundation through which Windows brings age-appropriate protections and parental choices into more of the digital experiences encountered by children and teens every day. A child’s account should help unlock safer, more age-appropriate experiences wherever they use Windows. This is the first in a series of posts on family safety on Windows. Over the coming months I’ll share what we're building — in the account, in the platform, and in the tools we provide to parents, educators, and developers. As Pavan recently shared, Family is a key focus area in our commitment to improving Windows quality. We'll build in the open: shipping new capabilities, listening closely to what families tell us, and refining as we learn. 

From account to safer experiences 

Every experience on Windows starts with identity, and for consumers, that foundation is the Microsoft account (MSA).  MSA enables Windows to understand key context about the user in a consistent and privacy-conscious way: 

• Whether the user is a child, teen, or adult 
• Whether parental controls or consent apply 
• Whether age verification has been completed 

This creates a simple, scalable model:  User account → age signal → age-appropriate experience and controls  Because this foundation is tied to the account, protections are designed to follow the user across Windows and apps, creating safer experiences consistently, not just in individual features. This enables product experiences to support a user’s stage of life. Protections are matched to children, teens, and adults. 

Extending safety across the ecosystem with the Windows Age APIs 

As experiences expand across apps, services, and AI, one challenge becomes clear: how can these experiences consistently understand and respect a user’s age?  To address this, Windows is introducing a new platform capability: the Windows Age API.  This API brings age awareness beyond the operating system by making it available across the entire Windows ecosystem so that apps and services can deliver age-appropriate experiences using the same trusted foundation. By making age awareness available as a platform capability, Windows helps developers build safeguards into experiences from the start rather than placing the burden on children and families to manage protections app by app.  The Windows Age API offers the following capabilities: 

• GetUserAgeRangeAsync: Provides non-personally identifiable age group categories for apps to utilize in providing safe and age-appropriate user experiences, while protecting the date of birth data and overall privacy of users. Age groupings available via the API include- under 10, 10-12, 13-15, 16-17, 18+.
• GetAgeVerificationStatusAsync: Provides verified age status for scenarios when self-reported age is not sufficient.
• CheckAgeStatusAsync: Extends the functionality of the legacy CheckUserAgeConsentGroupAsync API to offer child, minor, or adult classification globally and as defined by regional policies.

These signals are designed to protect privacy: 

• Apps receive only the age-related signal needed for the experience and not sensitive personal data such as full date of birth
• Users remain in control through consent and platform-level controls
• Age information is handled consistently at the platform level to reduce unnecessary sharing and fragmentation 

This enables a new level of consistency across Windows experiences. Apps can recognize when a user is under a certain age and adjust features accordingly, helping create safer, more appropriate interactions without requiring manual setup. This platform approach also helps make protections more consistent and accessible, so safer experiences do not depend on whether a family discovers or configures controls in each individual app.  Just as importantly, this extends to emerging experiences, including AI, where applying age-appropriate safeguards is increasingly important as innovation continues to evolve.  By making this a platform capability, Windows drives safety which is built-in and available across apps, services, and new scenarios.   For more details, including developer guidance, check out the Windows Age API documentation found at https://aka.ms/windows-age-api. 

Building toward high-confidence age assurance 

In many cases, understanding age is not enough. Increasingly, certain experiences require high confidence that a user is an adult.  To support this, Microsoft is expanding age assurance through the Microsoft account using Microsoft Age Verification (MAV), a centralized platform that enables users to verify their age once and use that status across Microsoft experiences. Developers can access this verified status through Windows Age APIs.   Age verification is already available in Microsoft Storefronts in Singapore, Brazil, and Australia. As more regions around the world expand regulatory requirements for age verification, Microsoft will add support for those geographies and product scenarios.  MAV creates a simple, consistent model:  Verify once → use everywhere  Verified status is stored with the Microsoft account and can be used across Windows and apps to enable appropriate experiences, helping reduce friction while improving safety.  

Making safety clearer from the start 

We’re also improving how parental controls are surfaced during device setup, so families can more easily understand available protections and make informed choices from the very beginning.  In regions such as France and others, Windows is raising the visibility of parental controls and consent experiences during setup, designed to increase awareness of the available offerings and enabling early application by parents.  

Family Safety and Parental Controls 

With Family Safety built into Windows, parents can set up a child's device and manage screen time, apps, and content in one place. Over the past six months, we’ve focused on making those everyday moments more dependable – faster parental approvals, clearer activity reporting, and more overall control – guided by what parents told us mattered most. You can read more about what’s improved and what’s coming next here: Listening to families. Improving Microsoft Family. 

Raising the bar for digital safety 

Digital safety must be built into the platform—not added on later.  With Microsoft account as the foundation, and with investments like the Windows Age API expanded age assurance, and available parental controls, Windows is working to support a safer digital environment that is also age-appropriate, privacy-conscious, and easier for families to navigate.  Our goal is to help create experiences where safety, privacy, and participation can work together across the Windows ecosystem. 

Availability 

The Windows Age APIs are broadly available to Windows Insiders now and will be available to all Windows users soon. The CheckAgeStatusAsync API will be available with a future update.

Building an extension has never been easier. Rapid adoption of AI-assisted coding is enabling developers to build extensions faster than ever. We have seen that momentum on the Edge Add-ons site. More developers are building, iterating, and submitting extensions, which is great for the ecosystem and ultimately gives users more choice. It also creates a challenge: how do we keep up with the pace at which the ecosystem is growing, while maintaining a high bar for quality?

Speeding up extension reviews

We know time matters to developers. Whether launching an extension, fixing an issue, or making improvements, waiting for a review can slow progress. Last year, we introduced an expedited review process for high-quality and high-value extensions. Since then, submission volumes have continued to increase, and our review pipeline has experienced additional strain, causing an increase in extension review turnaround time. At the same time, at Edge we have always held a very high bar on quality. So, the challenge in front of us was to reduce the turnaround time for extension updates while ensuring the quality of extensions is maintained. To address this challenge, we've introduced automation for many of the repeatable validation checks that are part of the review process and streamlined how reviews move through our pipeline. This doesn't change our review standards or reduce the checks an extension must pass. Instead, it helps us identify known policy violations and security issues more consistently while allowing reviewers to spend more time on complex cases that benefit from human judgment. The result is a more efficient review process that helps extensions move through the pipeline faster while maintaining the high quality and security standards developers and users expect from the Edge Add-ons site. For developers, this mean bug fixes and new features reach your users sooner. Our objective is to make Edge the easiest place to build, publish, and grow an extension. Faster reviews are just one part of that investment. We continue to look for ways to reduce friction across the developer journey while maintaining a trusted marketplace for users.

Recognizing quality as it improves

As more extensions become available on the Edge Add-ons site, helping users discover extensions they can trust is equally important. The Featured badge has long helped users identify high-quality extensions in the Edge Add-ons site. It serves as a trust signal, highlighting extensions that demonstrate a strong commitment to quality, reliability, security, and user experience. The Featured badge is awarded to select extensions that align with Best practices for extensions. Our evaluation considers more than 60 quality signals across multiple dimensions of an extension. Today, much of our evaluation process is automated to make it more consistent, objective, and scalable as the ecosystem expands. But quality is not static. As we continue to refine our badging criteria, and as developers continuously improve their extensions by fixing issues, refining experiences, and responding to user feedback, we automatically update badges on the Edge Add-ons site. And now, to more quickly recognize quality improvements, we're refreshing Featured badges every 15 days. With this more frequent cadence, high-quality extensions can earn recognition sooner, and developers receive faster feedback on their investments in quality. At the same time, users benefit from a more up-to-date view of the extensions that meet our quality standards. Our goal is simple: make it easier for users to find extensions they can trust while ensuring developers who invest in quality are recognized more quickly.

Breakthroughs in computing become real through the experiences developers create. Our goal is to have Windows be the best platform for developers. That means pairing the latest in hardware innovation with software optimized for development. At Build 2026, we introduced a developer-optimized Windows 11 experience to build and ship faster and shared how Windows is becoming the open platform for secure agentic experiences. Today, we're taking the next step with Project Zenith, a ready-to-code distraction-free Windows experience on developer-class devices with 64 GB+ unified memory and 250+ GB/s memory bandwidth, so developers can jump right in. Project Zenith will first become available with AMD’s Ryzen AI Halo, with more devices from our OEM and silicon partners available in the coming months. Project Zenith devices come with a preconfigured Windows setup for development, and a set of tools curated for what developers reach first.  On these devices, developers can run 30B+ parameter models locally and unmetered - accelerating experimentation while helping reduce reliance on metered cloud tokens. Project Zenith represents Windows at its best - listening to developers, responding with purpose and working across our ecosystem to raise the bar for what a developer PC can be.

Improving the baseline Windows 11 experience

Since the beginning of this year, we’ve been dedicated to making Windows 11 more performant, reliable and refined across day-to-day experiences. From Search to File Explorer, and everyday memory usage, Windows is becoming faster, calmer, and more polished with more control over the experiences you care about most. Project Zenith devices will benefit from all these improvements, while delivering an optimized developer environment you’ve been asking for.

Ready to code out of the box

Project Zenith comes with a set of pre-installed tools spanning languages and runtimes, source control, and productivity tools. Windows Terminal and Visual Studio Code are pinned to the Taskbar by default, putting your favorite tools within immediate reach. We’ve also pre-configured Windows Settings for coding across File Explorer, Search, Start, and the Taskbar. File Explorer shows file extensions, hidden files, the full path in the title bar, and the details pane, with long-path support enabled. Recently used files and folders and sync provider tips are turned off for a cleaner workspace. In Search and Start, Command Palette is enabled, while Start menu tips and account notifications are turned off to reduce distractions. Windows Subsystem for Linux (WSL) has become foundational for running Linux workloads on Windows. Last year we open-sourced WSL. Building on that momentum at Build 2026, we integrated WSL more deeply into Windows with WSL containers to provide a built-in way to create, run, and interact with Linux containers directly on Windows. Together, with Project Zenith, these choices create a calm, and meaningful starting point for development. Project Zenith is not about prescribing a single workflow. You can continue to configure, extend, and personalize your environment around the tools, languages, and frameworks you prefer. It is about beginning from a better baseline, shaped by the settings and tools developers reach for first, so a new device works with you to accelerate your workflows.

Secure platform for agents on developer-class hardware

We’re entering a new era of software development. Agentic applications are becoming more common, and developers need a secure foundation for building and running them. At Build 2026, we shared how Windows is evolving to provide exactly that – combining OS-enforced identity, containment with Microsoft Execution Containers (MXC), and enterprise-grade manageability for agents.  Project Zenith devices will benefit from these platform investments from day one, providing a secure environment for developing and running agents. As AI models become more powerful, agentic coding workflows demand continuous compute. By shifting some of that intelligence to the edge, we are achieving token economics and transforming the developer experience: frontier models tackle frontier problems, while everything else runs locally at scale. With 64 GB+ of unified memory and 250 GB/s+ of memory bandwidth, Project Zenith devices enable developers to run capable coding models locally and unmetered, helping lower token costs.

Project Zenith is just the beginning

Over the past year, we have continued to evolve Windows around how development happens today. From WSL and Windows Developer Configurations to Intelligent Terminal and expanded on-device AI capabilities, each investment is focused on helping developers stay in control and build faster.  Project Zenith brings together the work happening across the Windows platform into a tailored experience on new developer-class PCs. Project Zenith also reflects how Windows moves forward with our ecosystem. By working with our OEM partners, we give developers choice across devices and performance tiers while preserving the ready-to-code experience. The hardware may vary, but the developer promise is consistent - powerful for modern development, thoughtfully configured and ready for developers from the start. Project Zenith is the result of listening to developers about what they need from Windows today, and where they want the platform to go next. As AI continues to transform software development, we are committed to evolving Windows alongside the community that builds on it. We are excited to see what you will build, making Windows the platform where the next generation of applications, agents, and AI experiences come to life.

The Interop 2027 call for proposals is open, submit your ideas now! Over the past six years, the Interop project has helped bring key web platform features to a state where developers can rely on them across browsers. Technologies such as CSS layout and utilities, View Transitions, anchor positioning, popover, and shadow DOM have all benefited from the focused effort that Interop makes possible. This year, browser vendors have continued to work across a broad set of focus areas including View Transitions, Navigation API, CSS Anchor Positioning, WebRTC, WebTransport, Dialogs and Popovers, custom highlights, container style queries, and more. These efforts are helping move the web platform toward a future where developers can spend less time working around browser differences and more time building great experiences. Interoperability remains one of the most important challenges facing the web. New capabilities are constantly being standardized and implemented, but they're most valuable when they work consistently everywhere. That's why the Interop project continues to evolve each year, guided by input from developers, framework authors, browser vendors, and standards communities. Today, we're opening the proposal process for Interop 2027. If you've encountered a web platform feature that behaves differently across browsers, a standards-based capability that's difficult to rely on today, or an area where better interoperability would unlock new opportunities, we want to hear from you. The proposal submission period is open now and will remain open through September 23, 2026. The Interop team will review submissions and evaluate them using the Interop selection process, with the goal of publishing the final Interop 2027 scope early February 2027.

What makes a strong proposal?

The strongest Interop proposals share a few common traits:

• They solve a real developer problem. Make sure you explain how inconsistent browser behavior or missing support affect developers in practice.
• They have ecosystem impact. Evidence from developers, frameworks, libraries, issue trackers, surveys, or real-world sites helps demonstrate that a problem is worth solving.
• They're about standards-based features. Features with a stable specification and broad standards support are better candidates for Interop.
• They can be measured. Interop relies on Web Platform Tests (WPT) to track progress, so proposals should either have strong existing test coverage or a clear path to adding it.
• They are scoped for meaningful progress. A focused, concrete proposal is often easier to evaluate and more likely to succeed than a broad request such as "improve CSS" or "fix forms everywhere."

For more information, check the Interop Proposers Guide.

Submit your proposals now

Submit your ideas now, even if you're unsure they qualify. Even proposals that aren't selected can help us understand where you're experiencing pain and where future interoperability work is needed. On the Microsoft Edge team, we're always listening to developer signals, and unselected Interop proposals often constitute clear needs from developers. We track these needs, and others, on our Top Developer Needs dashboard to influence progress on the highest-impact, long-running issues. We'll be refreshing this dashboard early next year.

In a significant milestone for the platform, Microsoft and NVIDIA recently announced NVIDIA RTX Spark. These new devices are the most powerful and efficient, thin-and-light Windows PC ever, built with the Arm architecture. In the fall of 2026, devices from Microsoft Surface, ASUS, Dell, HP, Lenovo, and MSI will be available. NVIDIA's entry into the Windows on Arm silicon family joins the Qualcomm Snapdragon X series of chipsets that have already established Windows on Arm as the premium experience across Microsoft Surface Copilot+ PCs. The market is sending a clear signal: more silicon providers and more OEM partners are investing in Windows on Arm because customer demand is growing for these powerful and efficient Windows devices and experiences.   Alongside the expanding PC landscape, the Windows app ecosystem continues to grow rapidly. As powerful Arm-based devices reach more customers, this motivates developers to build and optimize for the platform. Consequently, as the app catalog grows, customers have even more reason to choose Windows on Arm hardware. That virtuous cycle is now clearly in motion. The app catalog growth is evident in the Works on Windows on Arm site. This site catalogs over 7000 verified apps and games available for Windows on Arm and is built with compatibility data from Microsoft. Given the breadth of Arm-capable hardware available from multiple silicon providers and the depth of the app catalog, Windows on Arm has become a first-class platform for any workload.   App Assure, Microsoft's app compatibility program, with its dedicated Arm Advisory Service, continues to expand the Windows on Arm ecosystem. We continue working side by side with a diverse set of software development companies to bring their apps to the Windows on Arm catalog, ensuring that no customer is left behind. The goal of this blog is to share App Assure's latest progress report: a roundup of some of the most notable new additions to the Windows on Arm app portfolio since our previous update. 

STEM and education apps

This is a rapidly expanding category that demands its own section. Science, Technology, Engineering, and Mathematics (STEM) as well as education tools all play a critical role in how people learn in classrooms, research environments, or via independent study. As Windows on Arm devices become more prevalent, developers in this space now recognize the opportunity to reach learners and professionals who value portable, power-efficient devices without sacrificing performance. The growing number of STEM and education apps now available reflects increasing investment aligned with these needs and the growing adoption of Windows on Arm devices by educational customers. [caption id="attachment_57881" align="alignnone" width="931"] Recent STEM and education apps available on Windows on Arm devices[/caption]

Security apps

Security remains foundational for Windows customers, and it spans far more than a single tool or workload. Modern environments require layered protection across endpoints, consistent device management, and secure connectivity, especially as work increasingly happens across hybrid, mobile, and distributed environments.  Arm-based devices are designed with security at the core, integrating hardware, firmware, and software protections to help defend against modern threats. In addition to the built-in security features, strong support for Windows on Arm in endpoint protection, endpoint management, VPN and Zero Trust solutions helps ensure that customers can adopt these devices without compromising their security posture.   Our previous update showcased well-known apps from companies including Norton, CrowdStrike, and McAfee in the Endpoint Protection space; VMware, Beyond Trust, and Cisco in the Endpoint Management space; and Nord, Zscaler, and Palo Alto Networks in the VPN and Zero Trust space. The continued expansion of the Windows on Arm security app ecosystem, as seen below, highlights how software vendors are aligning with customer expectations for secure, manageable Arm‑based deployments. [caption id="attachment_57875" align="alignnone" width="967"] Recent security apps available on Windows on Arm devices[/caption]

Productivity apps

Productivity apps remain the cornerstone of how people get work done on Windows. Whether managing projects, collaborating with teammates, organizing information, or communicating across teams, these apps are essential to our customers’ daily work. The growing list of productivity apps now available reflects both customer demand and increasing momentum from developers building with Arm as a first-class Windows platform. The new apps listed below join those previously announced from industry leaders such as Google, Adobe, Slack, Trello, and Dropbox. [caption id="attachment_57868" align="alignnone" width="1024"] Recent productivity apps available on Windows on Arm devices[/caption]

Creativity, social media and entertainment apps

Windows devices are as important for work as they are for expression, connection and entertainment. From creative tools to social platforms and media experiences, these apps enable users to create, share and unwind throughout their day. Developers continue to bring rich, engaging experiences to Arm-based devices, ensuring users don’t have to choose between productivity and creativity. Our previous update saw brands such as Camtasia, Blender and Figma release Arm apps. Below are the latest additions. [caption id="attachment_57869" align="alignnone" width="1368"] Recent creativity, social media and entertainment apps available on Windows on Arm devices[/caption] The takeaway is clear: Windows on Arm is no longer defined by potential, but by a rapidly expanding ecosystem of devices with apps available across workloads that customers depend on most. As developers continue to invest in Arm-native experiences and compatibility, customers gain more choices, flexibility, and confidence in adopting the next generation of Windows devices. As the ecosystem continues to expand, the Microsoft App Assure team is ready to assist software developers interested in bringing their apps to Windows on Arm. Through our Arm Advisory Service, we offer expert guidance, technical workshops, code samples, and an escalation path to Microsoft engineers ready to assist with software development. Reach out to us here to learn more. Finally, don’t forget to bookmark https://worksonwoa.com/ for a comprehensive and continuously updated list of all the apps available on Windows on Arm devices.

Microsoft Edge is moving to a two-week release cycle, and the WebView2 Runtime is moving right along with it. Starting with 152, the WebView2 Runtime will align with Edge's new two-week major-release cadence, instead of the previous four-week cadence, for faster security fixes, platform improvements, and other capabilities.

• On the week of August 27, the WebView2 Runtime version 152 will be last major version to be released 4 weeks after the previous version.
• On the week of September 10, version 153 will be the very first version to be released only two weeks after the previous version.
• After that point, a new major version will be released about every two weeks, aligned with the Edge release cadence.

The WebView2 SDK release cadence will also be updated. Instead of the monthly releases, SDK versions will be released when there are new features, bug fixes, security updates, and other improvements to share. When we do ship an SDK, it will be released on the same date as the corresponding Runtime release.

What this means for your app

If you use the Evergreen Runtime distribution mode, which is the default, there's nothing you need to do. Your users' machines will start getting security and platform fixes at the more frequent cadence. If you ship a Fixed Version Runtime instead, you stay in control of when you update, but new major versions arrive more often. Plan to validate and pick up new versions more frequently, so you don't fall behind on security fixes.

Recommended actions

We recommend that you test your WebView2 app by using the Beta preview channel of Microsoft Edge to catch any bugs before they roll out to your users. Early testing is the best way to catch app-specific issues before they reach Stable. To learn more, see Prerelease testing using preview channels. We also recommend automating the validation of your app's core workflows with the WebView2 preview channels. You can automatically test your app by using Microsoft Edge WebDriver. See Automate and test WebView2 apps with Microsoft Edge WebDriver. Finally, report regressions early so we can address them before the Stable release. You can report bugs by using the WebView2Feedback GitHub repository.

Stay current

Moving with Edge means your users get a safer, more capable web platform sooner, and you get a single, predictable release train to plan around. We're grateful for the partnership of the WebView2 developer community, and we'll keep sharing details as the new cadence rolls out. To learn more, read our recent announcement, check out our release notes, and review the release schedule. And, as always, feel free to share feedback with us.

What’s new and next with Windows 365

Five years in, Cloud PCs are enabling secure, flexible work not only for information workers but also the frontline, developers, and emerging AI agents. We are excited to share our most recent developments and where things are going next. Watch this Microsoft Mechanics demo to take a closer look and read on to learn more: https://youtu.be/MK-hCq7Su1w

Empowering developers

For developers, we made several announcements at Microsoft Build 2026, including ready‑to‑code Cloud PCs preconfigured with common development tools, now in preview. We also announced general availability of a new Windows 365 GPU Select offering along with 32vCPU Windows 365 Cloud PCs for graphics-intensive and compute-intensive workloads like software development, data modeling, simulations, and AI/ML. Select language models (LM) can run directly on Cloud PCs, enabling developers building AI‑powered apps to use Cloud PC compute to build and iterate effectively without incurring token costs. Always available Cloud PCs also enable long-running builds, test loops, dev environments, and AI-assisted workflows to be persistent beyond the limits of a physical device, so work can continue on a Cloud PC even when a physical device goes to sleep.

Enabling AI agents

For agent-makers, we made Windows 365 for Agents generally available earlier this year. Windows 365 for Agents provides a collection of Microsoft Entra-joined, Microsoft Intune-managed, and policy-enforced Cloud PCs for agents to execute multi-step workflows across software, including opening apps, navigating interfaces, entering inputs, and processing data. Companies such as Login VSI, Simular, and WorkspaceDNA are already building AI agents that can run on Windows 365 for Agents. And at Microsoft, we’re using Windows 365 for Agents to power agentic experiences such as computer-use scenarios in Researcher. Looking ahead, we’re continuing to introduce new capabilities to enable secure use of enterprise-grade AI agents. Now in preview, Windows 365 for Agents supports accessing on-premises applications using agents’ identities, enabling organizations to extend automation across legacy business applications without modernizing existing applications. Also in preview, we’re introducing support for linking Windows 365 for Agents Cloud PC agent pools to either a Microsoft Entra group or a Microsoft Intune Autopilot device preparation profile. This enables IT administrators to manage Cloud PCs for agents at scale by applying security and compliance policies, deploying required applications, maintaining consistent configurations across agent pools, and using existing Intune workflows. Additionally, with Windows 365 support for Microsoft Execution Containers (MXC) becoming generally available in the coming months, customers can securely run supported agent workloads, from coding agents, like GitHub Copilot CLI to autonomous agents like OpenClaw, on managed, always-available Cloud PCs using process and session isolation with familiar enterprise security and governance controls.

Strengthening security

Our commitment to security remains as important as ever. Cloud PCs enable organizations to reduce their attack surface by having data remain secure in the Microsoft Cloud – not on dispersed endpoints. Earlier this year, we introduced context-based redirections using Microsoft Entra authentication context, enabling more precise control over how users access Cloud PCs. We’re further strengthening defenses against endpoint threats by safeguarding sensitive data on-screen. With output protection capabilities becoming generally available in September, displayed content on a Cloud PC can stay shielded from screen scrapers and other endpoint threats.

Streamlining management

We’re also enabling IT admins to further streamline Cloud PC management by leveraging AI. With the new Windows 365 monitoring and reporting platform becoming generally available in September and a new agent for Windows 365 administrators now available in limited preview, IT admins can more easily monitor Cloud PC health in Microsoft Intune, investigate issues, identify likely root causes, and accelerate troubleshooting through a guided conversational experience that streamlines analyzing operational signals and insights across the Cloud PC environment. Complete this form or contact your Microsoft account team to express interest in participating in the Windows 365 admin agent preview.

Partnering on the next chapter

As we look ahead to the future, we remain committed to evolving to meet the diverse needs of customers, enabling new ways of working securely, fueling human and agentic productivity and ensuring business continuity. Hear from Judson Althoff, CEO, Microsoft Commercial Business, on how an AI-ready foundation serving employees and agents can help every business deliver the productivity, flexibility, and security their workforce needs to thrive. https://youtu.be/JZ9TX2fUTp8 We are grateful for the customers and partners who have shaped this journey with us, and we’re excited to build the next chapter of Cloud PCs together.

Hi Windows Insiders, File Explorer is one of the most used experiences on Windows. It's where you get work done: organizing files, finding what you need, and moving content seamlessly across local storage and the cloud. Earlier this year, we shared our commitment to improving Windows quality, with a focus on performance, reliability, and craftsmanship. In File Explorer, that means investing in the foundational work needed to improve the experience end-to-end: reducing hangs and delays, improving responsiveness and reliability, addressing customer-reported issues, and removing friction from everyday tasks. But quality is also about continually evolving the experience to feel more modern, intuitive, and efficient for the millions of people who rely on File Explorer every day. Today we're sharing progress on both fronts. Alongside continued investments in File Explorer performance and reliability, we are introducing a substantially redesigned context menu experience that's faster, simpler, and more customizable than ever before. This new context menu experience is now rolling to Windows Insiders and represents one of several major improvements underway as we continue to modernize File Explorer.

Fewer bad moments

What people remember most are the worst moments. A single freeze while renaming a file, a slow right-click, or a Home view that flashes and reloads can outweigh dozens of smooth interactions. That reality has guided our approach to improving File Explorer. We focused on the everyday experiences people rely on most and set clear goals to make those interactions faster, more reliable, and less disruptive. Improving the moments that matter most We've profiled and invested in improving the performance and responsiveness of File Explorer. File Explorer now launches faster, and the overall experience feels more consistent and predictable. We’ve analyzed the issues behind many of the freezes, hangs, and delays users encounter, and eliminated dozens of potential stalls and interruptions in the experience.  As a result, you'll see fewer freezes and flashes when browsing, renaming files, navigating, or selecting multiple files. There are many more improvements to come, and these changes are designed to reduce disruptions and make File Explorer feel more responsive and reliable day to day.

Improving the details that matter every day

Our work extends beyond performance and reliability improvements. Many of the requests we hear from customers aren’t about major new features, they’re about the small interactions that happen every day.  We’ve continued refining File Explorer based on that feedback, removing friction and improving the details that help make everyday tasks feel more natural and predictable. For example, file renames no longer get interrupted by background file synchronization, and case-only filename changes now appear immediately. We’ve also improved navigation workflows.  The Address Bar now supports a wider range of inputs, including paths with quotation marks and double backslashes. Support for opening folders in a new tab with a middle-click has also been expanded to the Address Bar and Home page folders, making multitasking faster and more intuitive. Smaller usability improvements add up as well. Home now preserves whether sections are expanded or collapsed so you can pick up where you left off. File sizes are now displayed using appropriate units such as KB, MB, and GB, making them easier to understand at a glance. The Details pane has been reorganized so file properties are easier to find and review. Many of these improvements came directly from customer and Windows Insider feedback. They represent just the beginning of our ongoing effort to improve the everyday experiences people depend on most.

Putting you in control of the context menu

Right-clicking is one of the most common actions in Windows. If it doesn’t work as intended, or is difficult to navigate, it can derail your workflow. When we launched Windows 11, we introduced a new context menu with a modernized design, improved organization, and a new approach to application extensions. Over time, though, the menu became cluttered and sluggish, and we recognized the need to dramatically reduce the time between right-clicking and having a menu that’s fully ready to use. Today, we're excited to announce an updated context menu that delivers a faster, simpler, and more customizable experience. The new design reduces top-level clutter, keeps commonly used actions easy to access, and introduces a new Settings experience that gives you more control over what appears in the menu. [caption id="attachment_179130" align="aligncenter" width="1024"] The new right-click menu.[/caption] Faster to open The first thing you'll notice is that the menu opens much more quickly. For something used as often as the context menu, speed is part of good design. A lot of that comes from behind-the-scenes engineering improvements, and a good part comes from a cleaner default menu, with the full set of options just a click away in Settings. Clutter isn't only a visual problem; it slows the menu down because every app that adds its own options can make the menu do extra work each time it opens. Your menu, your control Part of the broader push we’re making across Windows 11 is making the operating system calmer by default, with more personalization and control. Each person uses the context menu in different ways, so we’re adding more customization to allow you to choose the layout that works best for you. At the bottom of the new context menu, you’ll now find “Customize menu”, as a shortcut to its Settings page, where you can shape the menu around your preferences, your habits, or the years of muscle memory you’ve built with a specific configuration. [caption id="attachment_179131" align="aligncenter" width="760"] The new Context Menu page in the Settings app, under Personalization.[/caption] The top section lets you turn built-in Windows commands like Send to or Create shortcut on or off. Some of these commands, like Print, weren't available in the Windows 11 context menu before and can now be switched on if you want them. The next section is about options for app extensibility, so you can choose which app extensions appear in the main menu or submenu, including hiding the submenu altogether. Finally, the last section is about where the most common commands live. We know many people have years of muscle memory from the Windows 10 menu, so we've added options to bring that feel back. You can list the main commands (Cut, Copy, Paste, Rename, Delete, and Share) inline directly in the menu instead of as a row of icons, and you can move Properties down to the very bottom. As we continue refining this experience with Insider feedback, our goal is to make right-click feel more responsive, predictable, and personal.

Building a healthier File Explorer for the long term

We are committed to continue doing the hard work and consistently improving File Explorer month after month. Not every update will be obvious on its own, but together they should make File Explorer feel faster, polished, and more dependable across tasks users do most. Your feedback continues to shape every step of this journey. Keep it coming through Feedback Hub, and we'll continue sharing our progress as this work evolves. The File Explorer team

Back in 2020, we committed to Manifest Version 3 (MV3) as the future direction of the Chromium extensions platform. Since then, we've worked with developers, listened to feedback, and continued evolving Microsoft Edge toward a more secure and performant extensions foundation. Today, we're announcing the next phase of that journey. With 95% of the top MV2 extensions on the Edge Add-ons website already moved to MV3, the ecosystem has made meaningful progress. Beginning in August 2026, Microsoft Edge will start the consumer transition away from Manifest Version 2 (MV2) extensions and toward MV3. Our goal is to complete the consumer transition by the end of 2026, with enterprise deprecation following in early 2027.

The ecosystem is ready for the next step

This is a significant milestone for the extensions community, and one we have approached deliberately. Microsoft Edge continued to support MV2 extensions so developers, enterprises, and users who depend on specific extensions had more time to adapt. The move to MV3 has come a long way. MV3 offers security and performance improvements over MV2, and developers across the ecosystem have done the work to modernize their extensions. To put some numbers around the progress the ecosystem has made, there are only 58 MV2-based extensions in the Edge Add-ons website with any meaningful usage. Of these, only three don't have a publicly available MV3-based extension already available. Developers and users have spoken: the vast majority of extensions of all types—from password managers to VPNs to ad-blockers—have successfully transitioned to MV3 with no loss of customer functionality. We're committed to working with all developers with MV2-based extensions to smoothly move their users to MV3 extensions.

What to expect next

Starting in August 2026, a subset of users with MV2 extensions installed will begin to see notices on the Manage Extensions page (edge://extensions) and on Microsoft Edge Add-ons product detail pages. The very few developers with an MV2 extension will see a similar notice in Microsoft Partner Center, along with a direct outreach from our team to help them complete the migration. Over the next few months, MV2 extensions will be gradually turned off by default. Users will be notified in advance and directed to recommended MV3 versions where available. These changes will start in the Canary, Dev, and Beta channels and gradually broaden to Stable in the following months, with the goal of completing the consumer transition by the end of 2026. Managed devices will not be affected during the consumer rollout. Enterprise deprecation will follow in early 2027. We will keep the community updated on the status of the rollout on a regular cadence.

What developers should do now

For developers who still maintain MV2 extensions, now is the time to complete the move to MV3. Ship an MV3 version of your extension and submit the update through Microsoft Partner Center. The Migrate an extension from Manifest Version 2 to V3 guide outlines the required changes. This progress only works because of the developers who have already moved their extensions to MV3 and shared feedback along the way. Thank you for your partnership and continued support in improving Microsoft Edge. If you run into questions during your migration, please reach out to the Microsoft Edge extensions team. We're happy to help.

In March I wrote to you about our commitment to Windows quality. Four months in, the team and I have been reflecting on our progress and wanted to share an update. We know there is more to do, especially in getting these improvements to all customers. We’re not slowing down. What we said we'd focus on In my letter, there was a list of immediate changes we committed to making. This included:

• More taskbar customization
• Integrating AI where it’s most meaningful
• Reducing disruption from Windows Updates
• Faster and more dependable File Explorer
• More control over widgets and feed experiences
• A simpler, more transparent Windows Insider Program
• Improving the Feedback Hub experience

We also named three areas of focus at the start: performance, reliability, and well-crafted experiences. Since then, the team has been deeply focused on these priorities. Many of these improvements have been rolling out to Windows Insiders over the last few months, and they'll start rolling out more broadly across Windows 11 PCs beginning this fall. Here's what our work so far looks like

• Earlier this month, we began previewing improvements to Windows Search Box, including a calmer home screen, clearer results, removing promotional content from web results and more.
• At Build 2026 in June, we introduced a number of improvements to the developer experience on Windows including a developer-optimized Windows 11 experience to build and ship faster, announcing and later delivering a public preview of WSL containers, Windows 365 with developer configuration, Microsoft Execution Containers and much more.
• We've strengthened the fundamentals of WinUI 3 and extended it into more of the Windows shell, including Widgets and the new Run experience, with Autoplay dialog and more File/Folder Properties dialogs coming soon to Windows Insider Preview Experimental builds. And with substantial improvements in memory efficiency and latency, these investments are strengthening the platform foundation needed to accelerate the modernization of Windows 11 and the broader application ecosystem.
• In May, we began previewing changes to Taskbar and Start, which included the ability to move your taskbar positions as well as provide more personalization of Start.
• In May, we shared updates on how we've been simplifying AI throughout the OS, starting with inbox apps, part of a broader shift to make AI in Windows more intentional and focused on the experiences that provide the most value to customers.
• We have previewed several improvements to File Explorer, including foundational architecture enhancements designed to improve responsiveness and reliability across launch and navigation. We’ve addressed long-standing feedback about Home, including unstable transitions and blurry thumbnails. We also made updates to address File Explorer reliability, readability, and usability across the Address Bar, file size formatting, keyboard navigation, and renaming, and there’s more to come soon.
• In May, we previewed updates to the widgets and feed experience, giving you more control over and making them quieter by default.
• In May, we introduced the Driver Quality Initiative (DQI), a comprehensive, ecosystem-wide effort designed to fundamentally raise the bar on driver quality, reliability, and security across Windows. Since March, we've improved reliability across some of Windows' most common connectivity experiences, including improved USB4 docking performance, improved compatibility with Bluetooth devices like AirPods, as well as major gains in printer connectivity, including reducing in-network printer discovery failures.
• We're continuing to invest across the full stack, from the kernel and shell to the apps and developer tools built on Windows, so performance improvements benefit the broad range of ways people use Windows. Building on the responsiveness and scheduler work we described in May, application launches and experiences like Start, File Explorer, Search, and Snipping Tool are faster and more responsive. Our focus has been on improving these experiences, so they are responsive, free of stutters and delays, and customers enjoy a reliable experience every time. Boot and logon times are also improved. Additionally, developers benefit from faster compile times, streamlining enterprise workflows.
• Alongside all of these areas, we’ve steadily been introducing several improvements to the memory efficiency of Windows, from taking advantage of a more efficient memory allocator to reduce overhead across apps and components, continued tuning of WinUI 3 so that apps built on it use less memory by design, as well as driving efficiencies across Chromium and Webview2 components when they appear in the operating system.
• Throughout this effort, we've improved Windows Hello to make signing in with your face or fingerprint more reliable, helping you get to your desktop faster. It's part of our broader focus on the everyday experiences that should just work, making Windows feel more polished, dependable, and consistent every day.
• In April, we began previewing changes that reduced disruption from Windows Updates and provided more control like the ability to skip updates during the out-of-box experience (OOBE), extending update pauses and more.
• In April, we made changes to the Windows Insider Program to become simpler and easier to navigate, with fewer channels and more control over the features you flight.

What happens between now and the end of the year Across our focus areas, the work continues as we bring these enhancements to general availability and deliver ongoing improvements customers can feel across performance, reliability, and craft. We're going to take everything we've learned since March and keep listening and closing the loop on your feedback. The signal from you is clear: keep going. We intend to. We're staying focused on our initial areas, and we're expanding into four new ones.

• Onboarding and setup. Delivering a faster and more efficient out-of-box experience.
• Memory optimization for 8GB and above. Reducing Windows memory footprint to deliver a fast and responsive Windows experience across the PCs customers use every day.
• Family. Providing a faster set up and making it easier for families to access useful parental controls.
• Voice. Making voice more natural and fluid to interact across the apps you use every day.

What's energized us most The last few months have energized us. Meeting Windows Insiders at our monthly meetups and hearing what you think has been one of the best parts. This is work our engineers love and we want you to feel it in the product. We know we have more to do, and we're grateful to be on this journey with you. Pavan

• Experimental (Future Platforms): Build 29639.1000

Notable new features:

[Updated 4 August 2026: thank you for the feedback from Insiders who found that the taskbar improvements had not made their way to the latest Beta build on release. After a slight delay, those improvements are now included in the build, a reboot maybe required. We look forward to continuing receiving your feedback for the new Taskbar improvements.]

[Taskbar]

Release channel: Experimental, new to Beta and Beta (26H1) Alternate Taskbar Position

• You can now change the position of taskbar on your screen. In Settings > Personalization > Taskbar > Taskbar Behaviors, you can select the side of the screen you want your taskbar on: bottom, top, left, or right. In these other positions, tooltips, flyouts, and animations will still come from the taskbar, and most customization settings like never combine taskbar icons will work with all locations.

• Support for touch gestures, Search box, and Ask Copilot in alternate locations is in progress. Auto-hidden taskbar and touch optimized taskbar are not currently supported. Smaller taskbar is currently supported only for top and bottom positions.

[caption id="attachment_178963" align="aligncenter" width="1024"] Screenshot of the taskbar in the left-aligned position.[/caption] Smaller Taskbar

• We’re introducing a smaller taskbar for users who want to maximize screen space, especially on smaller devices. While the default taskbar remains unchanged, this setting provides a more compact experience with smaller icons and a reduced taskbar height, giving you more room for your apps. Core elements like Start, Search, and the system tray scale appropriately to stay aligned and consistent.

• To change your taskbar size, go to Settings > Personalization > Taskbar > Taskbar behaviors > Taskbar size. When set to Small, both the icons and the taskbar height become smaller.

[caption id="attachment_178959" align="aligncenter" width="1024"] Side-by-side comparison of the standard and smaller taskbar heights on the same device and resolution, showing the additional screen space gained.[/caption]

[Adaptive Hibernate Policy]

Release channel: Experimental Updates to the adaptive hibernate policy to increase instances of instant-on resumes from Modern Standby and increased battery preservation at the low end of the battery.  Noticeable changes include less hibernation while the battery is above 80% and hibernating sooner when the battery is below 10%. Thanks, Stephen and the Windows Insider Program team

Release notes for Windows 11 Insider Preview Build 29634.1000 for Experimental (Future Platforms)

Changes and improvements gradually being rolled out [Voice Isolation in Voice Access]

• We're introducing Voice Isolation, a new option in Voice Access that helps it focus on your voice, even when others are speaking nearby. Whether you're in a shared office, an open floor plan, or at home with family around, Voice Isolation filters out other voices and background noise so Voice Access can better understand you. All processing happens privately on your device.
• Getting started Voice Access now offers three speech recognition modes under Voice Access settings > Improve speech recognition:
  • Voice Isolation — Filters out other speakers and background noise (one-time voice setup required).
  • Remove background noise only — Filters out non-speech sounds like typing or door slams. No additional setup needed.
  • No filtering — Default microphone input with no additional processing.
• To set up Voice Isolation, select it from the menu and follow the short, guided setup where you'll read a brief paragraph aloud so Voice Access can learn your voice. It only takes a minute, and your voice data never leaves your device

[Narrator] Braille displays now connect instantly with Narrator

• We're making refreshable braille displays easier to use in Windows. Narrator now supports displays that use the HID standard — an open industry standard for braille displays. If your display supports HID, simply connect it via USB and start reading — true plug-and-play with no additional setup required. For Bluetooth, pair your HID braille display in Settings > Bluetooth & devices just like any other accessory, and you can work wirelessly without being tethered to your PC.
• Compatible HID displays include models like the Orbit Reader 20, Orbit Slate 340, Freedom Scientific Focus 40, and APH Mantis Q40.
• HID braille displays now work during the initial Windows setup experience (OOBE) over USB — meaning users who are deaf-blind can set up their PC independently, right from the first screen.

Hello Windows Insiders, Today we're releasing build 28120.2546 for the Experimental (26H1) channel. Release notes can be found over in the Windows Insider Documentation Hub as usual, as well as below:

Changes and improvements gradually being rolled out

- This update includes a small set of general improvements and fixes that improve the overall experience for Insiders running this build on their PCs.

[Smart card removal policy]

- Administrators can now configure Azure Virtual Desktop (AVD) and Windows 365 sessions that use Microsoft Entra ID (RDS AAD Auth) authentication to automatically disconnect when a redirected smart card is removed. This extends smart card removal policy enforcement to Microsoft Entra authenticated remote sessions, helping organizations meet security and compliance requirements.

[Narrator]

- Braille displays now connect instantly with Narrator. - We're making refreshable braille displays easier to use in Windows. Narrator now supports displays that use the HID standard, an open industry standard for braille displays. If your display supports HID, simply connect it via USB and start reading with no additional setup required. - For Bluetooth, pair your HID braille display in **Settings > Bluetooth & devices** just like any other accessory, and you can work wirelessly without being tethered to your PC. - Compatible HID displays include Orbit Reader 20, Orbit Slate 340, Freedom Scientific Focus 40, and APH Mantis Q40. - HID braille displays now work during the initial Windows setup experience (OOBE) over USB, meaning users who are deaf-blind can set up their PC independently right from the first screen. - You can customize braille input and output options anytime in **Settings > Accessibility > Narrator > Braille**.

[Voice Access]

- Voice Access now supports Portuguese (Portugal), Portuguese (Brazil), and Korean (South Korea).

[Settings]

Hello Windows Insiders, You’ve been asking for search that is faster, more relevant, and easier to use—whether you’re opening an app, finding a file, or changing a setting. Because the Windows Search Box is where many people start, we focused first on making results more dependable, easier to scan, and clearer before you click.

Windows Search Box improvements gradually rolling out today to Windows Insiders

Today, we’re rolling out several improvements to Windows Search Box available to Windows Insiders in the Experimental channel. These improvements are gradually rolling out via Controlled Feature Rollout so not all Insiders will see them right away. You can reboot to see if you receive them today. They are also available via feature flags.

• A calmer home screen. Search home has been simplified to reduce visual clutter and make it easier to get back to recent searches quickly.

• Clearer results. Search does a better job showing where a result comes from—app, setting, file, web result, or Store suggestion—so it’s easier to tell what you’re looking at and where you will go before you click.

• Promotional content has been removed from web results. Web results show the most relevant answer, instead of first showing related products and promotions, helping search feel more focused and less distracting.

• You’re in control of web and Microsoft Store results. A new setting in Settings > Privacy & Security > Search lets you choose whether web and Microsoft Store suggestions appear alongside local results.

• Local results prioritized when they’re the better match. Apps, settings, and files more reliably appear ahead of web and Store suggestions when your content is the stronger match. System items like This PC and Recycle Bin are easier to discover.
• Finding apps is more forgiving. Search is better at handling typos, dropped letters, extra letters, and partial words for apps. Queries like “utlook” can still find Outlook.

• Settings results are improving. We’ve made a first round of ranking improvements to help more relevant settings appear higher in results, with more tuning planned in the coming months.

• Finding files is improving. Search is better at surfacing the right local files with added support for two-character file searches. We’ve also made improvements to show cloud and connected files in results when they’re the stronger match. These changes help you get to the document, download, or folder you are looking for faster.
• Reliability is improving. Improved search reliability, including reducing likelihood of crashing and loading issue, with more work underway.

Try the changes and give us feedback

These improvements become available to Windows Insiders today in the Experimental channel. The changes in this post reflect the feedback you’ve shared, and we’ll keep refining them as they roll out to more Insiders. Share your thoughts in Feedback Hub (WIN + F) under Desktop Environment > Search. Jeff & Anderson   NOTE: Experiences vary by region.

Windows has adapted to emerging threats for decades, all while operating at unparalleled scale. It's our responsibility to bring clarity, transparency and sustained investment so customers understand what is happening, what Microsoft is doing and how they can reduce their exposure. The pace of vulnerability discovery is changing with advances in AI making it possible to find more issues, faster, across more code, with new mechanisms that can accelerate both discovery and analysis. The fastest way to reduce customer exposure is to find issues before attackers can use them. Windows is expanding its ability across the platform to find issues earlier, accelerate the engineering work to fix them, strengthen validation and deliver timely, high-quality updates that keep customers protected.

Finding vulnerabilities earlier and at greater scale

By applying AI across security analysis, we can identify patterns faster, prioritize risk and scale vulnerability discovery across the Windows codebase. This helps reduce the time between discovery and customer protection. It includes using Microsoft Security’s multi-model agentic scanning harness (MDASH), which utilizes multiple models including leading third-party AI vulnerability discovery models. To run MDASH at Windows scale, Windows set up dedicated cloud infrastructure for scanning and proving. A scanner pipeline scans critical binaries and validates candidates using multi-model debate across multiple model families. Confirmed candidates then flow to a separate, Windows-specific prove pipeline that helps eliminate remaining false positives, so only the highest-confidence findings reach the engineering team. This automation helps handle a larger volume of potential vulnerabilities and shortens the review window for new ones, shrinking the attack window for zero-day exploits. This effort extends beyond Windows as we work across Microsoft to drive broader adoption of these tools and practices throughout both the company and the wider ecosystem. We partner closely with AI-powered scanning teams across Microsoft’s product divisions, sharing insights, comparing best practices and aligning on key findings. In parallel, we collaborate with the Microsoft Security Response Center (MSRC) to continuously refine the end-to-end process from vulnerability discovery and issue filing to remediation and validation. We also regularly reassess our prioritization and rollout strategy based on lessons learned and feedback gathered through our Chief Information Security Officers’ (CISOs) engagements with customers. We continue to evolve our internal systems and practices so that vulnerability discovery is not treated as a separate activity, but as part of how we build, review and improve Windows before new features or updates are released. As a part of this we are updating our Secure Development Lifecycle (SDL) best practices to ensure our secure-by-design approach explicitly accounts for potential AI-enabled attack techniques and exploit paths. That means using AI to help identify potential issues earlier in the development process, while relying on human expertise to evaluate findings, make risk-based decisions and ensure fixes meet the quality bar customers expect. As AI helps defenders discover more issues, customers will see a higher volume of security updates included in each security release. This is evidence that defenders are getting better at identifying and addressing issues. Our focus is to effectively utilize these AI tools to support faster protection, stronger engineering systems and more actionable guidance for customers.

Fixing responsibly with AI and engineering discipline

Windows is evolving our engineering and validation systems to reduce the time from discovery to protection, with areas where customer risk is greatest. As we build our end-to-end system from discovery to remediation of vulnerabilities on Windows, we’re making the following investments to help ensure that we are not compromising update quality as we gain speed:

• We are integrating AI into our process to compress the path from discovery to a validated fix, helping engineers understand failures faster, propose candidate fixes consistent with the surrounding code, surface related issues elsewhere in the codebase and select the regression tests most likely to be affected by a change.
• Windows updates undergo validation across a range of testing environments, including the Security Update Validation Program (SUVP) and internal validation designed to help evaluate compatibility, reliability and real-world usage scenarios. This broad validation helps identify functional, application compatibility and quality issues before updates are broadly released.
• We’re also investing in new technology, including Windows-specific tools and agentic harnesses, to enable end-to-end generation and validation of fixes using AI, keeping humans in the loop when it comes to code review.

Customers rely on Windows updates to protect their environments, and they also need confidence that updates will deploy smoothly across diverse devices, applications and configurations. That is why quality remains central to this work. As we increase the pace of vulnerability discovery and remediation, we are also committed to giving customers practical ways to test, deploy and monitor updates in their own environments. In cases where customers see signals of potential issues or regressions, they can connect with Microsoft Customer Service and Support to report the issue and/or learn if it is a known issue. In the event of an issue, we are able to employ Known Issue Rollback (KIR), a mitigation technology that allows customers to quickly revert a targeted change, fix, functionality or feature that caused the problem, to its previous behavior. This approach allows the customer’s security protections to stay in place instead of uninstalling an entire update to fix an issue.

Helping customers safely stay current

The most important guidance is to stay current and take security updates as soon as possible. Timely patching is one of the most effective ways to reduce exposure, especially as AI accelerates the speed at which vulnerabilities can be discovered and exploited. We also recognize that every customer's situation is different. Many organizations need to assess risk, validate updates, sequence deployments and prioritize critical assets. When Microsoft releases security updates, we share Common Vulnerabilities and Exposure (CVE) information and high-level guidance about the vulnerabilities addressed in the Security Update Guide, including available context on risk and mitigations where applicable. Customers should use that information to build a risk map for their own estate, prioritize protections for high-value targets and accelerate deployment where exposure is greatest. To help organizations prepare with less disruption, we also provide production-quality optional non-security preview ("D") releases ahead of the planned security update release for the following month for testing. These cumulative releases include new features and quality improvements. We target optional non-security preview releases for the fourth week of the month, two weeks before they'll see these features become part of the next monthly security update. These previews enable compatibility testing across a broad set of devices, applications and environments, helping identify issues earlier and increasing confidence in the quality and deployment readiness of the subsequent monthly security updates. Security is not just about responding faster to vulnerabilities. It is also about reducing exposure to security attacks. Windows is designed with multiple layers of protection enabled by default, strong identity protection with Windows Hello, the ability to reduce reliance on administrator privileges, trusted application experiences and hardware-rooted security. Together, these capabilities help organizations reduce exposure, strengthen resilience and provide a more secure foundation as organizations assess, test and deploy updates across their environment. To learn more about Windows security, see the Windows 11 Security Book or the Windows Server 2025 Security Book for your Server fleet. Windows also works closely with Microsoft Defender and the broader security ecosystem to help protect customers during the window between vulnerability disclosure and full deployment of security updates. Where possible, Microsoft Defender provides detections and protections that add another layer of defense. Through programs such as Microsoft Active Protections Program (MAPP), Microsoft also collaborates with security protection and antivirus partners so they can prepare protections for customers as security updates are released. We recommend that customers update their security endpoint software to the latest version and take daily signature updates for best protection. Intune helps teams identify gaps, enforce compliance and deploy fixes across endpoints, and Azure Arc makes it easy to connect Windows Servers outside Azure to Microsoft Defender for Cloud.

Tools that make patching easier

A holistic patch strategy depends on tools that help teams move across the full lifecycle: automate what can move fast, identify what still needs attention and limit exposure when devices or apps fall behind. Modern management capabilities such as Windows Autopatch with hotpatch enabled, available in Microsoft Intune, can help accelerate security updates and minimize disruptions for your Windows 11 devices. With Autopatch, customers can configure the automatic deployment of Windows security updates, driver updates and firmware updates, across rings with the option to pause based on reliability signals, so issues can be contained before they spread. Autopatch now surfaces a security-risk and compliance overview with device-level drill-down, so customers can see where their estate is exposed and how to reconfigure their policies to stay more secure. Windows Servers can be hotpatched as well through Azure Arc, enabling rebootless security updates for your critical infrastructure and VMs across the fleet, manageable at scale with Azure Update Manager. Intune Enterprise Application Management helps keep apps current. Microsoft Defender Vulnerability Management, Windows and Intune insights help teams understand remaining exposure and prioritize remediation. Compliance policies, Conditional Access and security baselines help enforce the desired state across the endpoint estate, or harden devices when updates can’t be applied right away. Together, these capabilities help customers move from a time-based patching cadence to a more continuous, risk-based approach. For practical guidance on operationalizing patching across endpoint estates, see the Microsoft Intune blog on building a patch strategy for today’s threat pace. https://www.youtube.com/watch?v=QdjSkbKXoJw

Building trust through continuous improvement

The threat environment will continue to evolve as AI advances, with researchers continuing to find new classes of issues and attackers looking for ways to move faster. Our response is to keep strengthening the systems that help us find vulnerabilities earlier, fix them responsibly and support customers through safe, timely updates. As the pace of vulnerability discovery increases, customers shouldn’t have to choose between speed and stability. Our job is to help customers stay protected while deploying updates with confidence. Windows will continue investing in the systems, engineering practices and platform protections needed to reduce exposure responsibly at global scale.

Welcome to New in Edge for developers, a new series featuring recent web platform updates in Microsoft Edge that help web developers build better sites and apps. In this first edition, we'll look at CSS gap decorations for styling the space between layout items, the focusgroup attribute for easier keyboard navigation, same-site PWA origin migration for moving an installed web app without disrupting users, and other improvements such as text-fit, flex-wrap: balance, and faster clipboard reads. We'll also preview upcoming features you can test today and share feedback on early, and highlight a few updates from across the broader web ecosystem, such as Modern Web Guidance, an AI coding agent skill helping you write better code.

Style layout gaps

CSS gap decorations let you style the gaps between items in flex, grid, and multi-column layouts directly, without relying on border hacks, pseudo-elements, or extra DOM elements. The new row-rule and extended column-rule properties, as well as the rule shorthand, support colors, patterns, and even the repeat() syntax for rich, consistent designs with minimal CSS.

.grid {
  display: grid;
  gap: 16px;
  row-rule: 1px solid #ccc;
  column-rule: 2px solid #333;
}

Learn more about CSS gap decorations and try our interactive playground.

Improve keyboard accessibility with focusgroup

The focusgroup HTML attribute gives you arrow key navigation for composite widgets, such as toolbars, tabs, or menus, for free. With the focusgroup attribute you get automatic arrow key handling and focus memory, without any custom JavaScript roving tabindex code. To learn more, check out Making keyboard navigation effortless.

Migrate your PWA to a new origin

You can now seamlessly migrate your Progressive Web App (PWA) to a new, same-site origin, preserving user installations and permissions. When a user installs a PWA, its identity is bound to its web origin (for example, example.com/app). Previously, changing the origin forced users to manually uninstall and reinstall the app. This is no longer necessary. Now, moving to a new origin such as app.example.com can happen without interruption to your users. To learn more, see Seamless PWA origin migration: Change domains without losing users.

And many other features

We've added many more web platform features to Microsoft Edge over the past fews releases. Check out the links below to find out more:

• image-rendering: crisps-edges: scale an image in a way that preserves contrast and edges, without smoothing colors or introducing blur.
• OpaqueRange for form control text: measure, highlight, and anchor UI to the text inside <input> and <textarea> without mirror-div hacks.
• Performance improvements when reading clipboard data: the Async Clipboard API now defers reading clipboard data until you call the getType() method.
• text-fit: scale the font-size of a text node so it perfectly fits the width of the box.
• light-dark() function for images: easily switch images based on the user's preferred color scheme.
• flex-wrap: balance: distribute the content of a flexbox layout on each flex line.
• scrollBy() / scrollTo() completion promises: run code when a smooth scrolling finishes, instead of relying on timers or scroll polling.

For even more updates, check out our web platform release notes.

Ready for testing

While not yet available for general use, the following features are available for early testing and feedback. You can test these new features either locally, or on your production website with your own users, by registering for an origin trial. Your feedback is crucial to help us shape these next features and ensure they meet your needs as developers, and the needs of your users.

Network Efficiency Guardrails: monitor and improve your site's load performance

Complex sites that embed third-party content and are maintained by many different teams tend to run the risk of regressing load performance when strong guidelines and monitor practices are not in place. This is exactly what the Network Efficiency Guardrails feature provides. It surfaces performance violations automatically in production, so your teams can catch and fix them without manually auditing every page. To learn more and test the Network Efficiency Guardrails feature, see Monitor and improve your web app's load performance.

<install>: install web apps with a single HTML element

The new <install> element gives you a browser-trusted install button with no JavaScript required. The browser controls the button's label and appearance, so a user click is a genuine signal of intent. You can even use the installurl attribute to build an app catalog that installs cross-origin web apps.

<!-- Install the current app -->
<install></install>

<!-- Install a different app -->
<install installurl="https://awesome-app.com/"></install>

To learn more, and get started, see our blog post: Install web apps with the new HTML install element.

CSS Grid Lanes: space efficient masonry layout

Grid Lanes is a new type of CSS layout that allows items to be automatically placed in the next available space, creating a space-efficient masonry-like layout without needing to specify row heights or use JavaScript. Grid Lanes is ideal for galleries, portfolios, and any design where items have varying widths or heights.

.grid {
  display: grid-lanes;
  grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));
}

To learn more, check out our demos.

New models and APIs for on-device AI

Our developer preview of the pre-release Aion-1.0-Instruct small language model is now available to use with the Prompt API and Writing Assistance APIs in Microsoft Edge. Aion-1.0-Instruct is smaller, faster, and more efficient than Phi-4-mini. It also expands support to significantly more devices. Check out our playground samples and share your feedback on GitHub. That's not all, starting with Microsoft Edge Canary or Dev 150, you can now also use the WebSpeech API to convert speech to text by using a local model, rather than a cloud-based solution. With on-device speech recognition support in Microsoft Edge, you can reduce your web app's running cost, be network independent, and improve privacy for your users. To learn more about Aion-1.0-Instruct, on-device speech recognition, and other on-device AI API updates, see Expanding on‑device AI in Microsoft Edge: New models and APIs for the web.

News from across the web platform

Beyond individual features, we also want to highlight a few updates from across the web platform and the broader web ecosystem.

Interop 2026 progress

The web moves forward by responding to new end-user and developer needs, and this is therefore a big part of what we do. But we also know that you need stability and consistency to build on. That's why we've been participating in the Interop project for the past five years, working with other browser vendors to identify and fix interoperability issues across browsers. This work is crucial to ensure that the web remains a healthy ecosystem where developers can build with confidence, and users can access content and applications regardless of their choice of browser. Interop 2026, the latest round of the project, is now well underway, and we've already made significant progress in fixing the issues identified during the planning phase. Between January and June 2026, Microsoft Edge's test pass rate increased from 77% to 97%, and we're hard at work on features such as Scoped custom element registries and WebTransport. Check out the Interop dashboard for more details on this year's focus areas and the progress made by all participating browsers.

Modern web guidance

We've partnered with the Google Chrome team to bring Modern Web Guidance to web developers. This ambitious project gives developers AI skills they can use with their AI coding agents, to build better web apps based on best practices under rigorous evals. We want to hear from you about this project. Did you try it? Did you find the results helpful? Are there other features you'd like to see included? Please let us know by using the public repo.

Closing words

On the Microsoft Edge web platform team, we're always listening to what users and web developers need, and pushing for a better, more capable web. Our work is never done; a healthy web is one that keeps improving to meet ever evolving needs. We hope these recent feature additions and early experiments are useful to you and your users. As always, let us know your feedback and other unsolved use cases. With your help, we can make your lives as developers easier, and your web products better for users.
