Announcing Windows 11 Insider Preview Build 23550 (Dev Channel)

Hi all, Yesterday Microsoft released Windows 11 Insider Preview Build 23550 to the Dev Channel.

Smooth upgraded on all DevChannel devices here,

Happy Upgrades!

What’s new in Build 23550

Voice Access in OOBE  

As part of the work mentioned in Build 23516 for making voice access available to use on more areas in Windows, voice access can be used for setting up your new Windows devices and navigate through OOBE (“out of box experience”). You can launch the accessibility flyout on the bottom right corner of their screens and click on voice access to enable it.

Users can use the accessibility flyout in OOBE to launch voice access.

NOTE: You will need to make sure you set up an internet connection while setting up a new device to enable the language model download and set up voice access to use it.  

You can navigate OOBE, insert passwords using the on-screen keyboard, type text using dictation and control your mouse and focus using number and grid overlays once voice access has been enabled.

Changes and Improvements

[Windows Subsystem for Linux]

  • The September 2023 update for the Windows Subsystem for Linux (WSL) is rolling out and includes networking improvements in the latest Insider Preview builds. See this blog post for more details.



  • 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.
