  • [Shared audio] New! Shared audio enables two people to listen to the same audio from a single Windows 11 PC at the same time. It uses Bluetooth® LE Audio broadcast technology to make sharing easy. For example, you can watch a movie while traveling or listen to music while studying together. To start sharing audio, open Quick settings from the taskbar, select Shared audio, choose two supported, paired, and connected devices, and then select Start sharing.

    • New! Magnifier now provides clearer and more consistent announcements when working with a screen reader. You’ll hear helpful announcements when you zoom in or out, switch views, turn color inversion on or off, or turn Magnifier on or off. This makes it easy to stay oriented while you work.

    • This update improves smoothness when moving Magnifier in lens mode.
  • [Task Manager]
    • New! Task Manager now offers improved visibility into NPU usage on PCs with an NPU.

Neural engines that are part of a GPU now appear on the Performance page, providing a more complete view of AI‑related activity. A new optional Isolation column on the Processes and Details pages shows which apps are running in an AppContainer. You can add any of the new columns by right‑clicking a column header in Task Manager and selecting them from the menu.
    • This update improves CPU speed display on the Performance page of Task Manager for VMs, so it doesn’t show higher than unexpected numbers after resuming from hibernate.
  • [Camera] New! Windows 11’s Multi-App Camera feature allows multiple applications to access your camera stream at the same time. Basic Camera mode in Windows 11 enables simplified camera functionality, useful for troubleshooting or improving stability when your camera is not working correctly.

    • This update optimizes the WinBio service to help reduce latency when resuming after Modern Standby.

  • [Storage]
    • The dialog is updated when creating a Dev Drive to now support specifying the size in GB instead of only MB. This has also been added when changing the size of volumes under Settings > System > Storage.
    • Updated Settings > System > Storage, so rather than seeing a UAC prompt immediately when you go to the page, you’ll only see it when going to view temporary files.
  • [Personalization] This update improves:
    • Color selection accuracy when adjusting your accent color to match your wallpaper when the automatic accent color selection is enabled in Personalization settings.
    • Wallpaper persistence reliability across restarts and upgrades, including better support for large‑resolution wallpapers and other scenarios to prevent solid color wallpaper fallback.

  • [Sensors] This update Improves resiliency against apps that could keep the sensor hub powered on and drain power, impacting battery life.
  • [HID Devices] This update improves battery life related to the HID / Input stack for failed HID devices. Power hygiene is also improved against applications that may initiate HID transfers during standby.
  • [Input] The update improves:
    • Reliability of invoking the touch keyboard on the login screen, when inputting your password to sign in, or changing your password.
    • Reliability of explorer.exe when closing the input switcher.
    • Performance of invoking or navigating to clipboard history.
