What's new in Windows 11 Build 23545 (Dev)

New features and improvements

Taskbar search

Microsoft is experimenting with different options for what will happen when you click a button inside the search bar on the taskbar. In some cases, you will be taken to a page dedicated to that search query. When you hover your mouse over after a search, a tooltip will always be displayed. The Search window should no longer appear on hover.


  • Rolling out the ability to quickly give your device a more friendly name to identify sharing to and from with nearby share under Settings > System > Nearby sharing.
  • You can now view and send files to Microsoft Teams contacts (work and school) in the system Share window if you are signed in with an Entra ID (AAD) account.


File Explorer

  • Fixed an issue that caused explorer.exe to crash when closing Explorer.
  • Fixed an issue where, when switching between a dark and light theme (or contrast mode), the address bar, toolbar, and context menu in File Explorer could use the wrong colors, making it difficult to see.
  • Fixed an issue where when launching File Explorer in a dark theme, you could see a bright white flash when loading content.
  • Fixed an issue where quickly opening two Explorer windows could cause explorer.exe to crash.
  • Several more fixes have been made to improve the launch speed of Explorer. Also fixed a memory leak that could impact performance over time.
  • Fixed an issue that caused explorer.exe to crash when navigating from the Home page.
  • Fixed an issue where attempting to open the Gallery section after adding new images could cause File Explorer to crash.
  • Fixed an issue where the progress bar on a tab would remain even after File Explorer had loaded the folder.
  • Fixed an issue where sorting changes were not saved for folders after navigating somewhere and returning back.
  • Fixed an issue where the icons on Explorer tabs could be incorrect.
  • Fixed an issue where desktop icons would turn white until you clicked the Refresh button in the desktop context menu.


Fixed a crash in explorer.exe that affected the stability of the taskbar.

Search on the taskbar

Fixed an issue due to which, in previous builds, Search would sometimes not launch.


  • Fixed an issue that resulted in the loss of support for Unicode Emoji 15 , introduced in build 23475 , and the updated color font format to  COLRv1 , available in build 23506 .
  • Fixed an issue where the suggestion window for Japanese and Chinese IME would not appear after using Connected Standby mode.
  • Fixed a crash in tabtip.exe that could affect text input in the last few flights.


Fixed an issue that prevented some Insiders from launching the Settings app in Safe Mode.


Fixed an issue that resulted in some Insiders attempting to take a screenshot of a window to receive screenshots of the entire screen rather than the app with focus.

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

Known Issues

Start Menu

Some apps in the Start menu's All Apps list (for example, PWA apps installed through Microsoft Edge) may appear as system apps when they are not.
