Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27902 to the Canary Channel. We are releasing ISOs for this build – they can be downloaded here.
We are also not planning to release SDKs for 27xxx series builds for the time being.
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
[File Explorer]
- Fixed an issue in the previous build where File Explorer might fail to persist any view changes. This also impacted desktop icons, which could unexpectedly move or change size back to default. Jen is happy this bug is fixed.
[Camera]
- Fixed an issue which could cause the Camera app to get stuck on some PCs in the last couple builds after switching between front and back camera.
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] There’s an issue starting with the previous build causing a small number of Insiders to experience repeated bugchecks with KERNEL_SECURITY_CHECK_FAILURE after upgrading. This may occur when connecting to VPN.
- This Canary Channel flight comes with a delightful blast from the past and will play the Windows Vista boot sound instead of the Windows 11 boot sound. The fix should be coming in a future Canary Channel flight soon.
[Settings]
- We’re investigating an issue in this build which could cause Settings to crash when interacting with the options under Settings > System > Power & Battery.
- [NEW] We’re investigating an issue where some of the apostrophes across text in Settings and settings-related dialogs are not displaying correctly and are showing random characters.
[Remote Desktop]
- You may see extreme graphical distortion and rendering issues using remote desktop on Arm64 PCs in this build.
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.
Thanks,
Amanda & Brandon
