Microsoft has released Windows 11 Insider Preview Build 27891 to Windows Insiders in the Canary Channel. The latest builds have deprecated Windows PowerShell 2.0, which the update resolves. The update also resolves issues related to the "Reset this PC" option, the taskbar not displaying acrylic material, Windows update downloads being stuck at 2%, and certain characters not rendering correctly for Insiders. The update also resolves concerns related to File Explorer, settings, Bluetooth functionality, window minimizing animations, CPU graphs on the Performance page, and audio performance. The update resolves issues related to font corruption in application menu items, distorted playback controls in the Media Player, and unexpectedly prolonged LDAP queries from applications. The update also resolves concerns regarding print previews that may appear somewhat unclear. Additional details regarding the removal of Windows PowerShell 2.0 will be provided in a forthcoming update for Windows 11.

Announcing Windows 11 Insider Preview Build 27891 (Canary Channel)

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27891 to the Canary Channel. 

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.
