Windows 11 Insider Build 27902: Key Updates, Fixes & Known Issues

Key Changes and Improvements​

• General Improvements:
  This build delivers a small set of general improvements and fixes that enhance the overall experience for Insiders.

Fixes​

• File Explorer:
• Fixed an issue where File Explorer might fail to persist view changes.
• This also impacted desktop icons, which could unexpectedly move or revert to default size.
• Camera App:
• Fixed a bug where the Camera app could get stuck when switching between front and back cameras on some PCs.

Known Issues​

• For Copilot+ PCs:
• If you join the Canary Channel from Dev/Release Preview/retail, you will lose Windows Hello PIN/biometric sign-in (error 0xd0000225, “Something went wrong, and your PIN isn’t available”). You can recreate your PIN via “Set up my PIN.”
• Bugcheck:
• A small number of Insiders may experience repeated bugchecks with KERNEL_SECURITY_CHECK_FAILURE after upgrading, possibly when connecting to VPN (started with the previous build).
• Boot Sound:
• This build, by accident, plays the Windows Vista boot sound instead of the Windows 11 boot sound. A fix is coming in a future build.
• Settings:
• Possible crashes in Settings > System > Power & Battery.
• Apostrophes in some Settings text may display incorrectly as random characters.
• Remote Desktop:
• Extreme graphical distortion and rendering issues when using Remote Desktop on Arm64 PCs.

Notes for Canary Channel Insiders​

• Canary builds are early developmental platform changes, not tied to a specific Windows release.
• Features may be rolled out to only a subset of Insiders at first and may never ship in a public release.
• Some features may be available in Dev/Beta channels before Canary.
• Builds may not always be fully localized and may contain localization issues.
• To exit the Canary Channel, a clean Windows 11 install is required.
