Microsoft has released a new build of Windows 11 for Windows Insiders on the dev channel. Build 23550 has a couple of changes and a few nice fixes.

The Out of box experience (OOBE) now has voice control so you can use your voice to setup the OS, plus there is the September 2023 update for the Windows Subsystem for Linux (WSL).

Here are the fixes and known issues:



  • Fixed an underlying issue which was causing sporadic explorer.exe and Start menu crashes for Insiders in recent builds.

[File Explorer]

  • Fixed an issue which was causing thumbnails in Gallery to flash sometimes when scrolling.


  • Fixed an issue that was causing some icons in Start’s recommended section not to show correctly.

[Search on the Taskbar]

  • Fixed an issue where the magnifying glass wasn’t displaying correctly when search was set to “Search icon and label”.

[Task Manager]

  • Fixed an issue where the dialog when collecting a process memory dump erroneously said it was collecting a kernel memory dump.
  • Fixed an issue causing Task Manager to not launch for some Insiders.

NOTE: Some fixes noted here in Insider Preview builds from the Dev Channel may make their way into the servicing updates for the released version of Windows 11.

Known issues

[Start menu]

  • Some apps under All apps on the Start menu, such as PWA apps installed via Microsoft Edge, may incorrectly be labeled as a system component.

[Windows Copilot]

  • We heard feedback from Insiders in the Dev Channel that the Windows Copilot Preview is not available in some regions. We found an issue and plan to re-enable it for these Insiders with a fix in a future flight.
  • You can use Alt + Tab to switch out of Windows Copilot, but not back into it. Windows + C will move focus back to Windows Copilot
  • When first launching or after refreshing Copilot while using voice access you’ll need to use “Show grid” commands to click in the “Ask me anything” box for the first time.
