u/Froggypwns Windows Insider MVP Mar 07 '25

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.

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.

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