Windows 11 Insider Canary build 27891.1000

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27891 to the Canary Channel. We also have a Microsoft Store update rolling out to Insiders in the Canary and Dev Channels (details below).

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

Changes and Improvements

[Other]

Windows PowerShell 2.0 is deprecated and in the most current Insider Preview builds flighted to the Canary Channel, is removed. More information will be shared in the coming months on the removal of Windows PowerShell 2.0 in an upcoming update for Windows 11.

Fixes

[General]

We fixed the issue causing the “Reset this PC” option under Settings > System > Recovery to not work after upgrading the last few Canary Channel builds.
Fixed the underlying issue which was causing the taskbar to unexpectedly not showing acrylic material after upgrading to the latest Canary builds. This also impacted a few other scenarios, leading to unexpected black or white in some UI.
Fixed an underlying issue believed to be the cause of some Insiders seeing Windows update downloads to get stuck at 2% recently.
Fixed a few more languages including Vietnamese and Arabic that were still having issues with certain characters not rendering correctly for Insiders after the latest builds, causing nonsense to display in places like Task Manager and more. This impacted characters outside of A-Z.

[File Explorer]

Fixed an issue where if you opened the “…” menu in the File Explorer address bar to show the full list of folders for the current path, the dropdown might be cut off and the bottom of it inaccessible.

[Settings]

Fixed an issue in the previous build which could cause Settings to crash when opening microphone properties under Settings > System > Sound.
Fixed an underlying issue related to Bluetooth which could cause Settings or Quick Settings to crash on launch for some people.

[Windowing]

Fixed an issue which was causing the window minimizing animation to not display correctly in the previous flight.

[Task Manager]

Fixed an issue where the CPU graphs in the Performance page were still using the old CPU utility calculations.
Fixed an issue where after adding the new CPU Utility column, you might notice that System Idle Process always showed as 0.

[Audio]

Fixed an issue which could cause all system sounds to stop working (for example notification alert sound and the sound that plays when clicking the volume slider in quick settings), although audio in general was working on your PC.

[Other]

Fixed an underlying issue which was causing fonts in certain app menu items to unexpectedly appear corrupted or overlapped for some people. This also impacted typing in Word – where when using Hebrew a period may unexpectedly show as a 3, and in Thai typing space may show a 2.
Fixed an underlying issue which could cause the playback controls in Media Player to become distorted in the latest Canary flights.
Fixed an underlying issue believed to be the cause of LDAP queries from apps to take an unexpectedly long time in the previous flight.
Fixed an issue which could cause print previews to appear slightly blurry in recent Canary flights.

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”.

[Settings]

[NEW] We’re investigating an issue in this build which could cause Settings to crash when interacting with the options under Settings > System > Power & Battery.

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.
