[Taskbar & System Tray]

- Fixed an issue where when using Hebrew or Arabic as your display language, if you pressed WIN + T then arrow keys, focus through the taskbar icons would move in the opposite direction.
[Administrator Protection]

[Input]

Known issues
[General]
- [IMPORTANT NOTE FOR COPILOT+ PCs] If you are joining the Canary Channel on a new Copilot+ PC from the Dev Channel, Release Preview Channel or retail, you will lose Windows Hello pin and biometrics to sign into your PC with error 0xd0000225 and error message “Something went wrong, and your PIN isn’t available”. You should be able to re-create your PIN by clicking “Set up my PIN”.
- [NEW] We’re working on the fix for an issue causing night light to not work for some Insiders after the latest flight.
[Xbox Controllers]
- [NEW] Some Insiders are experiencing an issue where using their Xbox Controller via Bluetooth is causing their PC to bugcheck. Here is how to resolve the issue. Open Device Manager by searching for it via the search box on your taskbar. Once Device Manager is open, click on “View” and then “Devices by Driver”. Find the driver named “oemXXX.inf (XboxGameControllerDriver.inf)” where the “XXX” will be a specific number on your PC. Right-click on that driver and click “Uninstall”.
[Taskbar]
- We’re working on the fix for an issue where the taskbar icons aren’t increasing in size as they should when using your PC in a tablet posture.
Reminders for Windows Insiders in the Canary Channel
- The builds we release to the Canary Channel represent the latest platform changes early in the development cycle and should not be seen as matched to any specific release of Windows and features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.
- Many features in the Canary Channel are rolled out using Control Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
- Some features may show up in the Dev and Beta Channels first before showing up in the Canary Channel.
- Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
- To get off the Canary Channel, a clean install of Windows 11 will be required. As a reminder – Insiders can’t switch to a channel that is receiving builds with lower build numbers without doing a clean installation of Windows 11 due to technical setup requirements.
- The desktop watermark shown at the lower right corner of the desktop is normal for these pre-release builds.
- Check out Flight Hub for a complete look at what build is in which Insider channel.
