  • Windows 11 build 23545 is now rolling out in the Dev Channel.
  • This update pushes new fixes and various improvements.

Microsoft is rolling out Windows 11 build 23545 for computers in the Dev Channel of the Windows Insider Program. In this release, the software giant is rolling out fixes and improvements for existing features.

Build 23545 for Windows 11, according to the official changes, brings changes to the Windows Search and Share experience, and you will find a bunch of fixes for File Explorer, Taskbar, Input, settings, and more. This flight doesn’t contain any new features.

As part of the Windows Search changes, the development team is changing the hover experience to open the search box in the Taskbar with some different behaviors for when you click on the search highlight gleam. In some cases, clicking on the gleam will take you to a “” page for the search highlight. A tooltip will always be shown for the search highlight gleam when hovering over the search box. 

On the Windows Share feature, the sharing interface adds the ability to quickly give your device a more friendly name to identify sharing to and from with nearby share under the “Nearby sharing” settings page. In addition, Microsoft is rolling out the ability to find your Microsoft Teams (work or school) contacts and to send files to them directly within the built-in share interface when you are signed in with an Entra ID (AAD) account.
