Microsoft has released Windows 11 Insider Preview Build 27766 to Windows Insiders in the Canary Channel. The update resolves issues that have led to an increase in rollbacks and frequent crashes of explorer.exe for certain Insiders in the Canary channel. This also resolves an issue that results in the loss of Windows Hello PIN and biometric data for new Copilot+ PCs. The update resolves an issue where accent-colored window borders were not displayed when enabled, shadows around windows were not visible when enabled, and window launching animations were shown even when the setting to disable animations was activated.
Announcing Windows 11 Insider Preview Build 27766 (Canary Channel)
Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27766 to the Canary Channel.
Changes and Improvements
[General]
- This update includes a small set of general improvements and fixes that improve the overall experience for Insiders running this build on their PCs.
Fixes
[General]
- We fixed the issue where if you roll back from Build 27764 to an earlier build (including if the upgrade failed), you would see an “Your organization used App Control for Business to block this app” dialog when attempting to use or install certain third-party apps on your PC due to an incorrect policy being enforced.
- As of the latest Insider Preview builds in the Canary Channel, the main issues causing Insiders to experience an increase in rollbacks (with error code 0xc190010) when attempting to upgrade have been addressed. As a reminder, 0xc190010 is a generic error code that has multiple root causes, so if you’re continuing to experience issues, please file feedback (WIN + F) to investigate.
[Taskbar & System Tray]
- Fixed an underlying issue which was causing some Insiders in Canary to experience frequent explorer.exe crashes after they clean installed or reset their PC.
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”.
- We’re working on the fix for an underlying issue causing accent colored window borders to not be not displayed when enabled, shadows around windows not displaying when enabled, and window launching (and other) animations to show even though the setting to show animations is turned off.
