Microsoft has released Windows 11 Insider Preview Build 23606 to Windows Insiders in the development channel.

Announcing Windows 11 Insider Preview Build 23606 (Dev Channel)

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 23606 to the Dev Channel.

Changes and Improvements


  • Windows 11 is transitioning from Windows Speech Recognition (WSR) to voice access.  WSR is being deprecated. A dialog will pop up when WSR is opened directing you to try voice access and we have also added a banner under Settings > Accessibility > Speech as well. Voice access, our new assistive technology in Windows 11, uses on-device speech recognition, enabling control of your PC and authoring text without an internet connection. It will support multiple languages and custom commands in a future update (these features are now available for Windows Insiders to try in the Dev and Beta Channels). We recommend WSR users try and start using voice access today.

  • [ADDED] We’re beginning to rollout a change that renames the Phone Link settings page under Settings > Bluetooth & devices to Mobile devices. As part of this change, a new section will appear for allowing a PC to access mobile devices – this section currently does not introduce anything new yet and we’ll have more to share in a future flight. 

The Phone Link settings page is being renamed to Mobile devices.


[File Explorer]

  • Fixed an underlying issue causing the details pane in File Explorer to unexpectedly take keyboard focus sometimes.
  • Fixed an issue which was causing File Explorer to crash when accessing or scrolling Gallery.


  • Fixed a high hitting tabtip.exe crash when trying to use pen input in the previous flight.

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

[Copilot in Windows*]

  • When first launching or after refreshing Copilot in Windows while using voice access, you’ll need to use “Show grid” commands to click in the “Ask me anything” box for the first time.


  • You may experience a loading delay when the Microsoft Start feed is reenabled.
  • Announcements from the Microsoft Start feed are still shown on the taskbar after the feed is hidden.
  • The Widgets Board should automatically close and reopen when enabling or disabling feeds.
  • Keyboard navigation from settings subpages back to the top-level Settings page is broken.
  • Incorrect spacing and fonts used in some settings pages.

For developers

You can download the latest Windows Insider SDK at

SDK NuGet packages are now also flighting at  NuGet Gallery | WindowsSDK which include:

These NuGet packages provide more granular access to the SDK and better integration in CI/CD pipelines.

SDK flights are now published for both the Canary and Dev Channels, so be sure to choose the right version for your Insider Channel.

Remember to use  adaptive code when targeting new APIs to make sure your app runs on all customer machines, particularly when building against the Dev Channel SDK.  Feature detection is recommended over OS version checks, as OS version checks are unreliable and will not work as expected in all cases.
