Windows 11 Insider UpdateWindows 11 Insider Update

In the same week as Patch Tuesday updates, Microsoft has also updated the Dev channel for Windows 11 for the Insiders to Build 25179. This update does not include any new features, but a plethora of fixes and improvements for the OS. Moreover, Microsoft has also published an ISO for this build, so users can perform clean installations.

Let us discuss the new improvements this flight addresses as well as the issues it brings, then continue to learn how to upgrade to this flight through Windows Update and download its ISO image.

New in Windows 11 Build 25179

Improvements and Fixes

Here are the changes, improvements, and fixes implemented with this flight:

  • [General]
    • The spelling dictionary will now use a language-neutral word list and that will be synchronized across all devices that use the same Windows account. This feature can be toggled via Settings >> Accounts >> Windows backup >> Remember my preferences >> Language preferences.
    • An issue causing hangs and crashes in applications (like Excel) when attempting to print in the last few flights.
    • A few issues impacting explorer.exe reliability have been addressed.
  • [File Explorer]
    • File Explorer tabs and navigation updates are now rolling out to everyone in the Dev Channel.
    • Different experiences in File Explorer to show search results are being tested by Microsoft.
    • The Mount option when right-clicking things like ISO files should now show an icon in the context menu.
    • An issue where the min/max/close button might not be visible in File Explorer when using a contrast theme has been fixed.
  • [Input]
    • The Tamil Anjal keyboard for the Tamil language has been added. This keyboard is currently rolling out to a subset of Insiders while we evaluate the quality. To add it, make sure Tamil (India) is listed under Settings >> Time & Language >> Language & Region, and then click the ellipses (3 dots) next to the language, select “Language Options,” and add it to the list of keyboards.
    • A small tweak has been made to improve the key repeat rate for the traditional touch keyboard layout, as well as the default touch keyboard layout.
    • A sporadic crash impacting the reliability of the input switcher has been fixed.
    • An issue where when Suggested Actions was enabled, if you copied multiple items in a row to your clipboard history, some of the items might not display after you pressed the WIN + V shortcut keys, has been addressed.
  • [Widgets]
    • An issue causing Widgets preferences (temperature units and pinned widgets) to unexpectedly get reset to default has been fixed.
  • [Taskbar]
    • An issue that could lead to the taskbar overflow flyout unexpectedly appearing on the opposite side of the screen has been addressed.
  • [Settings]
    • An issue that was causing the Settings app to crash on launch has been fixed.
    • The alignment of the “Scan for phone” button displayed on Accounts >> Sign-In Options under “Dynamic Lock” when your phone failed to connect has been fixed.
    • The preferred state for the Suggested Actions setting under System >> Clipboard should persist upgrade going forward from this build.
  • [Windowing]
    • An issue where when resizing certain app windows near the edge of the screen when using mixed DPI monitors might unexpectedly cause the window to jump and shrink has been addressed.
  • [Other]
    • The default duration captured by powercfg -sleepstudy has been updated from 3 to 7 days.
    • A change was made so that the media controls in Quick Settings will more reliably not load old media you’re no longer using.
    • An issue causing one of the characters in the bugcheck text to not display correctly (as a box) when the display language is set to Chinese has been fixed.
    • An issue causing app install failures with error code 0x80080204 in the last few flights has been addressed.
    • The date/time recognition for existing supported locales when using Suggested Actions has been improved.

With these improvements and fixes, there are also a few known issues we think you should know about before upgrading to this build.

Known Issues

  • [General]
    • Devices with low disk space may be unable to update to this build and see a download error 0x80070001 in Windows Update. Microsoft recommends that freeing up disk space of 24GB or higher should fix the problem, while they work on a permanent fix.
    • Some games that use Easy Anti-Cheat may crash or cause your PC to bugcheck.
    • There are reports that audio stopped working for some Insiders after upgrading to the last flight.
    • An issue leading to some Insiders experiencing a decrease in FPS when playing certain games in recent flights due to the wrong graphics card being used.
    • There are reports of a few different apps having started crashing in recent builds.
  • [File Explorer]
    • The left-half of the File Explorer title bar may not be draggable via mouse or touch.
    • The up arrow is misaligned in the File Explorer tabs.
    • An issue causing Home, Documents, Pictures, and potentially other folders to become unexpectedly duplicated in File Explorer’s navigation pane or appear on the desktop.
    • An issue where the search box background in File Explorer might be the opposite color of your current mode.
    • An issue causing the delete key to unexpectedly not work on files in File Explorer.
    • An issue where the taskbar isn’t able to display if File Explorer is maximized and you have the taskbar set to auto-hide.
  • [Widgets]
    • The notification badge number may appear misaligned on the taskbar.
    • In some cases, the notification banner for some badging will not appear in the widgets board.
  • [Printing]
    • An issue in recent Dev Channel flights causing lines to not be included when printing tables from certain apps.

Some of these issues have prolonged over the last few flights in the Dev channel, but some of them are new with this flight. Hopefully, Microsoft will address these in future releases.
