What's new in Windows 11 Build 25163

Taskbar Overflow

Windows 11 Build 25163 Taskbar Overflow

Microsoft has reworked the taskbar to show icons that don't fit the visible area. Microsoft notes that the taskbar has been designed to offer users the most convenient way to switch and launch applications when space is constrained. The taskbar will automatically switch to overflow mode when new icons no longer fit in the screen area space. In this mode, a new button will appear on the taskbar to open a flyout that includes all applications that do not fit on the default taskbar.

Nearby Sharing

Improved device discovery with Nearby Sharing by using UDP protocol (network must be private for the feature to work) along with Bluetooth. Now when you try to share a local file from your desktop, File Explorer, Photos, Snipping Tool, Xbox, and other apps, you'll find more available devices in the Share system window, including desktop PCs.

Share a local file to OneDrive

Now, when you try to share a local file from your desktop, File Explorer, Photos, Snipping Tool, Xbox, and other apps that use the system share dialog, you can select OneDrive to directly upload the file to your cloud storage. In the Share window, you can also customize the sharing options for the uploaded file without opening the OneDrive app. This currently doesn't work on with AAD accounts.

Fixes in this build


File Explorer

  • Fixed an explorer.exe crash when dragging tabs around.
  • Did some work to fix a memory leak when using tabs with File Explorer.
  • Fixed an issue where the preview thumbnail for File Explorer in the taskbar, ALT + Tab, and Task View might show the title of an adjacent tab and not the currently selected one.
  • If “Show all folders” is enabled, the dividers in File Explorer’s navigation pane should no longer show. With this change, it should also address the issues where dividers were unexpectedly showing in some other folder pickers.
  • Fixed an issue where Narrator wasn’t reading out the titles of tabs as focus moved through them.
  • Fixed an issue where a closed tab might appear again in File Explorer after you dragged File Explorer across your monitors.
  • Fixed an issue where the tab row might unexpectedly expand vertically, covering the command bar contents.
  • Removable drives should no longer unexpectedly be displayed in a section by themselves in the navigation pane, which was breaking up the section with This PC and Network.
  • Fixed an issue where the add new tab button wasn’t clearly visible when using Aquatic or Desert contrast themes.
  • The add new tab button shouldn’t overlap with the minimize button in the title bar when using text scaling with a lot of tabs open anymore.


  • Fixed a rare explorer.exe crash that could happen while on a Microsoft Teams call, related to sharing windows from the taskbar.


  • Made a change to help fix an issue where using Windows Spotlight on the desktop might revert to a solid color background.
  • Improved the padding around the uninstall button when using Apps > Installed Apps in grid view.
  • Fixed a couple issues that could lead to Quick Settings crashing on launch.


  • Fixed an issue which was leading to certain apps freezing after a copy action if Suggested Actions was enabled.
