Major Points
Changes and Improvements
- The build brings a small set of improvements and fixes to enhance the experience for Insiders.
Fixes
- File Explorer: Fixed an issue where view changes (such as icon positions and sizes) might not persist, causing desktop icons to reset.
- Camera: Fixed an issue where the Camera app could freeze after switching between front and back cameras on some PCs.
Known Issues
- IMPORTANT for Copilot+ PCs: Joining Canary Channel from another branch (Dev, Release Preview, or retail) may cause loss of Windows Hello PIN and biometric sign-in, giving error 0xd0000225. You can fix this by recreating your PIN.
- Bugchecks: Some users may experience repeated bugchecks ("KERNEL_SECURITY_CHECK_FAILURE") after upgrading, especially when connecting to VPN.
- Blast from the past: This build temporarily plays the Windows Vista boot sound instead of the Windows 11 boot sound. This will be fixed in a future build.
- Settings: The Settings app might crash when interacting with options under System > Power & Battery, and some apostrophes may display as random characters.
- Remote Desktop: Severe graphical distortion and rendering issues may occur using Remote Desktop on ARM64 PCs.
Notes for Insiders (Reminders)
- Canary Channel builds are very early platform builds not tied to any specific Windows release; features may come, go, or never ship in retail.
- Features are rolled out to subsets of users first, using "Control Feature Rollout" (CFR) technology.
- Some features may show up in other Insider channels first.
- Some features may not be fully localized; report any language/translation issues you see.
- To leave the Canary Channel, a clean install of Windows 11 will be required.
- A desktop watermark is normal for these pre-release builds.
ISOs are available for those who prefer a fresh install.
