Insider Windows 11 Insider Canary build 27808.1000 - March 7

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27808 to the Canary Channel.

We are also not planning to release SDKs for 27xxx series builds for the time being.

Changes and Improvements​

[Task Manager]​

• We are beginning to roll out a change to the way Task Manager calculates CPU utilization for the Processes, Performance, and Users pages. Task Manager will now use the standard metrics to display CPU workload consistently across all pages and aligning with industry standards and third-party tools. For backward compatibility, a new optional column called CPU Utility is available (hidden by default) on the Details tab showing the previous CPU value used on the Processes page.

Fixes​

[Gaming]​

• Fixed an issue leading to some popular games like Roblox potentially having a bugcheck (green screen) on launch on Build 27802.

[Printing]​

• Fixed an issue where printing from some apps might cause a bugcheck (green screen) on Build 27802.

[Search]​

• Fixed an issue causing the search window to be blank for some Insiders recently when searching from the taskbar, due to a background crash.

[Graphics]​

• Fixed an underlying issue which could lead to Settings crashing when adding a color profile in Settings > System > Display.
• Fixed an issue which could cause color profiles to not load correctly after waking your PC from sleep.

[Power and Battery]​

• Fixed an issue where the colors in the new battery icon weren’t displayed correctly when you have your mode in Personalization > Colors set to certain options with Custom.

[BitLocker]​

• We did some work to improve the performance of loading early boot UI including the BitLocker PIN, BitLocker Recovery key, and boot menu screens.
• Fixed an issue for a small number of Insiders which was causing a BitLocker loop in Build 27802.
• Fixed an issue in recent flights where if you tried to run Get-BitLockerVolume, it unexpectedly showed an error.

[Other]​

• We believe one of the underlying changes in the previous flight addressed the issue causing reports that Hyper-V, and other features which rely on Hyper-V (such as WSL) weren’t working properly. If you continue having issues, please don’t hesitate to file a new piece of feedback in the Feedback Hub.

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] We are investigating a d3d9.dll crash which is causing multiple apps to fail to launch starting with Build 27802 for some Insiders.

Microsoft Store Update​

Windows Insiders in the Canary and Dev Channels running version 22402.x and higher of the Microsoft Store and higher will see the following improvement rolling out:

New Spotlight Design: We are trying out a new design for the “spotlight” on the department pages that show off more products at a glance for users to explore.


New spotlight design in the Store.

Updates to the Downloads Page: We’re continuing to improve the Downloads page with new sections to display updates for Microsoft-managed apps, which will be automatically applied, and updates for publisher-managed apps where you can update each independently. This ensures you can more easily view and manage updates for your apps and games.


New sections to display updates for Microsoft-managed apps in the Store highlighted in green boxes.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Microsoft Store.

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
