Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27909 to the Canary Channel.
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
[Administrator Protection]
- Fixed an underlying issue where the Xbox app wouldn’t launch when administrator protection was enabled. This may have also impacted other apps too, showing error 0xC0000142 or 0xC0000045.
[Settings]
- Fixed an issue where the battery percentage was unexpectedly missing from the top of System > Power & Battery in the last few builds.
[Remote desktop]
- Fixed an issue causing extreme graphical distortion and rendering issues using remote desktop on Arm64 PCs in the last couple builds.
[Other]
- Fixed a high hitting pcasvc.dll crash in the previous build.
- Fixed an underlying issue where if you disconnected the device you were casting to from outside of Media Player, Media Player would still show an option to disconnect from the device.
- Fixed an issue which was causing Remote Credential Guard scenarios between the latest Windows 11 builds and Server 2022 (and below) to fail.
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”.
- There’s an issue starting with the latest builds 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.
- 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.
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
