Announcing Windows 11 Insider Preview Build 25357

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 25357 to the Canary Channel. 

What’s new in Build 25357

New Widget: Facebook

Facebook is rolling out a preview version of their widget. To give it a try,  download the Facebook app from the Microsoft Store or update to the latest version of the app. Then open the widgets board and navigate to the widgets picker by clicking the “+” button at the top-right of the board to pin your widget.

The Facebook widget.

As you give this and  other new widgets a try, please let us know what you think through the Widgets feedback link in the widgets picker. You should expect to see additional new widgets as more developers create and release widgets for their apps.

If you’re a Windows developer and interested in creating a widget,  watch our tutorial video here. For an overview of the Windows widgets experience and design guidance for creating your own widgets, see  Windows widgets. For more information on creating a Win32 widget provider, see  Widget service providers. For information on PWA widget providers, see  Build PWA-driven widgets.

Changes and Improvements


  • The new volume mixer experience in Quick Settings mentioned  here is now available for all Insiders in the Canary Channel.

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.
