Windows 11 Insider Preview 25179.1000 rs prerelease 220805 1349

Windows 11 Insider Preview Build 25179.1000 Announcement (Dev Channel) 220805-1349

Good evening friends! Microsoft has released a new preview build of Windows 11 25179 to Windows Insider program members using the Dev channel. 

Full build number:  10.0.25179.1000.rs_prerelease.220805-1349 .

Changes and improvements

  • General:
    • The spelling dictionary will now use a language-independent word list, which should also sync across all devices using the same Windows account. Users can enable this feature in Settings -> Accounts -> Windows Backup -> Remember my settings -> Language settings. This feature only works with Microsoft accounts at this time. AAD support will come later.
  • Conductor:
    • Tabs and the updated navigation bar in File Explorer, which were introduced in build 22136 , are now available to all Insiders in the Dev channel. If you don’t see any changes, then restart your computer. If this does not help, then submit feedback to the Feedback Hub.
    • Microsoft is experimenting with different options for displaying search results in File Explorer.
  • Input:
    • Added Tamil Anjal keyboard for Tamil language. This is a popular keyboard for typing Tamil characters. Currently, this innovation is available only to some insiders, as engineers evaluate the quality and stability of the function. To add the feature, make sure Tamil (India) is selected in Options -> Time & Language -> Language & Region . After that, click on the “…” button next to this language, select “Language Options” and add it to the list of keyboards.
    • Implemented a minor tweak to improve key retry speed for the traditional touch keyboard layout as well as the default touch keyboard layout. This will make keyboards more responsive. So, if you hold down the Backspace key, then the speed will be 20 clicks per second.
  • Other:
    • Changed the default sleep duration fixed by the powercfg -sleepstudy command from 3 days to 7 days.


  • General:
    • We fixed an issue resulting in freezes and crashes when trying to print content from certain applications (such as Excel).
    • Fixed several issues affecting the stability of explorer.exe.
  • Conductor:
    • Now in the context menu, for example, for ISO images, the corresponding icon should be displayed for the “Connect” option.
    • We fixed an issue where the Minimize, Maximize, and Close buttons might not be visible in File Explorer when using a contrast theme.
  • Widgets:
    • We fixed an issue where widget settings (temperature units and pinned widget order) were unexpectedly reset to default.
  • Task bar:
    • We fixed an issue that could cause the taskbar overflow menu to appear unexpectedly on the opposite side of the screen.
  • Input:
    • Fixed a rare crash that affected the stability of the layout switcher.
    • We fixed an issue where if you copied multiple items in a row to the clipboard history, some of the items might not appear after pressing WIN + V if Suggested Actions is enabled.
    • The selected state for the “Suggested Actions” option under “System” -> “Clipboard” should now persist when upgrading to new builds.
  • Window:
    • We fixed an issue where, when using mixed DPI monitors, resizing some application windows at the edge of the screen could cause the window to unexpectedly jump and shrink.
  • Other:
    • Changes have been made so that the media controls in Quick Settings will no longer load outdated media data that you no longer use.
    • We fixed an issue that caused one of the characters in the GSOD text to display incorrectly (as an empty square) when the system language is Chinese.
    • We fixed an issue resulting in an application installation crashing with error 0x80080204.
    • Improved date/time recognition for existing supported localizations when using Suggested Actions.

Note. Some of the fixes listed above may be included in the cumulative updates for the October 5 release version of Windows 11.

Known Issues

  • General:
    • Some games that use Easy Anti-Cheat may crash or cause GSOD to appear on your device.
    • We are investigating reports of some Insiders having audio playback stop working after upgrading to a previous build.
    • Engineers are working on a fix for an issue that is causing some Insiders to experience FPS drops in some games when using certain graphics cards.
    • We are investigating reports that recent Insider builds have seen an increase in crashes in some applications.
  • Windows Explorer
    • The left half of File Explorer’s title bar may not be drag-and-drop or touch-enabled.
    • File Explorer tabs incorrectly display up arrow button next to the address bar. This will be fixed in future builds.
    • Engineers are working on a fix for an issue where the Home, Documents, Pictures, and other folders are unexpectedly duplicated in the navigation bar or appearing on the desktop.
    • Engineers are working on a fix for an issue where the background color of the “Search” field in File Explorer may be the opposite of what is set by the current skin.
    • Engineers are working on a fix for an issue where the Delete key doesn’t work with files in File Explorer. You can still use the context menu to delete files.
    • [New] Engineers are working on a fix for an issue where the taskbar may not appear when the File Explorer window is maximized to full screen and the taskbar is set to auto-hide.
  • Widgets:
    • The number in the notification indicator on the taskbar may be displayed with an offset.
    • In some cases, the notification information banner may not appear in the widget panel.
      • We are investigating reports that in the latest builds for the Dev channel, lines are not respected when printing tables from certain applications.

I wish you a successful update!
