Announcing Windows 11 Insider Preview Build 29634.1000 for Experimental (Future Platforms)
Hello Windows Insiders,
Today we’re releasing build 29634.1000 for the Experimental (Future Platforms) channel. Release notes can be found over in the Windows Insider Documentation Hub as usual, as well as below.
Renewed Windows Insider flight certificate
Today’s Experimental (Future Platforms) build contains a renewed Windows Insider flight certificate. Windows Insider Preview builds use flight certificates that are renewed periodically to help ensure Insider devices remain on supported builds and continue receiving future Insider Preview updates. The current flight certificate expires on August 11, 2026, so please update your device to a build containing the renewed flight certificate before that date.
For more information, please visit the certificate renewal FAQ.
Experimental (Future Platforms) moves to updated WIP UI
We conclude the full transition of all Windows Insider builds to the updated WIP channel UI, with those on the 29600 Preview Builds now seeing Experimental (Future Platforms) in the Windows Insider channel settings.

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
- 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. You can customize braille input and output options anytime in Settings > Accessibility > Narrator > Braille.
- The Windows 11 Account Control flyout has a refreshed, modern design and a clear subscription badge to make the user's account status instantly visible. This helps users easily identify their plan, discover benefits, and explore upgrades.
- The emoji panel (Windows key + period (.)) now uses GIPHY as the GIF provider, delivering a smoother GIF browsing and sharing experience following the deprecation of the Tenor API.
- Improved reliability of navigating to the Startup apps page in Settings.
- Improved reliability of loading the system tray area of the taskbar when using your PC in a tablet posture.
- Improved reliability of Start menu view preferences, ensuring your selected view is retained.
- Improved keyboard navigation when keyboard focus is set to the apps list within Start menu.
- Improved detection for triggering time zone change notifications.
- Improves the reliability of rendering content while scrolling for certain apps spanning across multiple monitors.

Showing ability to restart and shut down without installing pending updates[/caption]
If you choose Restart or Shut down, Windows will perform exactly that action, without unexpectedly starting an update. If you’re ready to install updates, you can explicitly choose one of the update options.
After a restart, Windows will attempt to restore previously opened applications faster, allowing users to return more easily to what they were working on.
This change is about is about making the Power menu more predictable, so when you need a quick restart or want to power off before heading out, Windows does exactly what you expect.
Showing all updates available under Available updates.[/caption]
Updates will download in the background, then will wait for a coordinated installation and restart. This installation and restart will align with the next Windows quality update or other update that you manually approve.
Users can always acquire all or specific updates earlier if desired by initiating download, install, restart (if applicable) for available updates. If none of these actions are taken, updates will be downloaded in the background and applied alongside the next scheduled Windows quality update.
