Microsoft has released Windows 11 Insider Preview Build 25272 to Windows insiders in the dev channel.

Announcing Windows 11 Insider Preview Build 25272

[Changes and Improvements]

[General]

• Moved Quick Assist out of Windows Tools so it displays directly in the Start menu’s All apps list and is easier to find.
• We are removing the suggestion action for searching copied text in Microsoft Edge and showing recommend common websites on the Recommended section in Start – both of which began rolling out with  Build 25247. Thanks to all the Insiders who gave us feedback on these two experiences. As a reminder, features and experiences we try out in the Dev Channel may get removed and never released beyond the Dev Channel as we incubate new ideas and get feedback from Insiders.

[WSL]

• Starting with Build 25267, the inbox version of Windows Subsystem for Linux has been removed. When you install a build with this change if you’re a WSL user you will need to update to the latest WSL version  outlined here in this GitHub post to ensure WSL continues working on your PC. Once you have done that, WSL will continue working on subsequent build updates. In future builds we’re looking to have this done automatically.

[Printing]

• Added a refresh button to the Windows print queue.

Fixes

[General]

• Fixed an issue where some Arm64 devices experienced a black screen while resuming from sleep or hibernate.
• Fixed an issue causing various UI elements in apps to disappear and reappear sometimes in recent builds.

[Search on the Taskbar]

The fixes only apply for Windows Insiders who received one of the different treatments for how search looks on the taskbar that began rolling out to Insiders with  Build 25252:

• We fixed the issue causing the search box on taskbar to not render correctly and display visual artifacts.
• Japanese IME candidate items should display correctly now inside the search box on the taskbar.

[Task Manager]

• Fixed an issue causing filtering by publisher name to not match correctly on the Processes page.
• Fixed an issue causing some services to not show in the Services page after filtering is applied.
• Fixed an issue which resulted in new processes appearing in a filtered list if launched while a filter is set.
• Fixed an issue where Task Manager did not display light and dark content correctly, rendering potentially unreadable text.
• Fixed an issue causing the Startup apps page in Task manager to not list any apps for some Insiders.
• If there are no matching search results, Task Manager will now explicitly say that.
• Fixed a Task Manager crash that could happen when attempting to end certain processes.
• You can now set focus to the search box by pressing CTRL + F.

[Narrator]

• Fixed an issue that was causing Settings to crash after turning Narrator on or off in Lithuanian and Hungarian builds.
• Narrator should now be working correctly with Windows Defender Application Guard for Edge.

[Live Captions]

• We fixed the issue that was causing Live Captions to not work in the latest Insider Preview builds in the Dev Channel.

[Input]

• When using the Japanese IME with Narrator, Narrator will no longer read out the entire composition string each time you press a key.
• The message displayed the first time you use ALT + Shift should no longer display if you only have one input language installed.
• Fixed an issue where the Surface Pen could no longer advance PowerPoint slides in recent builds.
• Made a change to help improve performance when using a high report rate mouse while gaming.
• Fixed an issue where if you used the touch gesture for opening the Start menu, it could get stuck halfway.
• Fixed an issue which could cause Excel to stop responding on certain mouse drag events when using the Japanese or Chinese IMEs.

[Settings]

• Fixed an issue which could cause a hang if you cancelled out of certification authentication when connecting to VPN.
• Fixed an issue which was causing Settings to crash when opening Power and Battery sometimes.
• Fixed an issue causing Quick Settings crashes sometimes when navigating to the Bluetooth section.
• Fixed an issue where the app icons under Settings > Apps > Default apps might be blurry.

[Windowing]

• Fixed an issue causing a black screen when ALT + Tabbing out of certain games in recent builds.
• The maximize button should no longer be slightly smaller than the close and minimize buttons when you highlight it in File Explorer and certain other apps while using dark mode.
• Fixed a couple DWM crashes that were introduced in recent builds.

[Other]

• Fixed an issue which was causing some Windows Security app crashes.
• Fixed an issue where the print queue was showing stale job information for printer connection printers.
• Fixed an issue where when creating a FIDO2 credential for a website in a browser, you might see the dialog twice in a row in certain cases.
• This build contains the fix for an issue impacting Windows Hello on certain PCs. We are continuing to investigate an issue specific to Arm64 PCs (see known issues).
• Fixed an issue which could lead to the Camera app showing that something went wrong if you pressed Pause while recording video.

NOTE: Some fixes noted here in Insider Preview builds from the Dev Channel may make their way into the servicing updates for the released version of Windows 11.

Known issues

[General]

• Using Windows Hello to sign in with facial recognition may not work on Arm64 PCs. A workaround for this is to use the Hello PIN path.

[Taskbar & System Tray]

• The taskbar is sometimes cropped in half when using the tablet-optimized taskbar. You may also see this issue on secondary monitors.

[Search on the Taskbar]

The following known issues only apply for Windows Insiders who received one of the different treatments for how search looks on the taskbar that began rolling out to Insiders with  Build 25252:

• In right-to-left display languages like Arabic, there are layout issues with the text in the search box on taskbar.

[Task Manager]

• Some dialogs may not render in the correct theme when applied from Task Manager Settings page.
• The data content area of the Processes page may flash once when theme changes are applied in the Task Manager Settings page.

[Widgets]

• We’re investigating an issue where the widgets board will get stuck open in an invisible state for Insiders in China (and potentially others), causing clicks on the left side of the screen to not work. If you encounter this, pressing WIN + D may resolve the issue.
• In right-to-left display languages like Arabic, content animates out of view before the widgets board resizes when clicking to expanded view of the widgets board.

For developers

You can download the latest Windows Insider SDK at  aka.ms/windowsinsidersdk.

SDK NuGet packages are now also flighting at  NuGet Gallery | WindowsSDK which include:

• .NET TFM packages for use in .NET apps as described at  ms/windowsinsidersdk
• C++ packages for Win32 headers and libs per architecture
• BuildTools package when you just need tools like MakeAppx.exe, MakePri.exe, and SignTool.exe

These NuGet packages provide more granular access to the SDK and better integration in CI/CD pipelines.
