Announcing Windows 11 Insider Preview Build 25284

Hello Windows Insiders,

Today we are releasing Windows 11 Insider Preview Build 25284 to the Dev Channel.

TL;DR

What’s new

New Widget

With the release of Windows App SDK 1.2 developers are now able to create widgets for their apps. Users can access these experiences on their Windows 11 widgets board in current Dev Channel Insider Preview builds.

Ready to try out a new widget? The Messenger app now has a preview version of its widget available. To give it a try, go to the Microsoft Store and update to the latest version of Messenger. 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.

As you give this widget 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.

For developers

You can download the latest Windows Insider SDK at aka.ms/windowsinsidersdk.

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.

About the Dev Channel

The Dev Channel receives builds that represent long lead work from our engineers with features and experiences that may never get released as we try out different concepts and get feedback. It is important to remember that the builds we release to the Dev Channel should not be seen as matched to any specific release of Windows and the features included may change over time, be removed, or replaced in Insider builds or may never be released beyond Windows Insiders to general customers. For more information, please read this blog post about how we plan to use the Dev Channel to incubate new ideas, work on long lead items, and control the states of individual features.

These aren’t always stable builds, and sometimes you will see issues that block key activities or require workarounds. It is important to make sure you read the known issues listed in our blog posts as we document many of these issues with each flight.

Build numbers are higher in the Dev Channel than the Windows 11 preview builds in the Beta and Release Preview Channels. You will not be able to switch from the Dev Channel to the Beta or Release Preview Channels without doing a clean install back to the released version of Windows 11 currently.

ALSO: Because the Dev and Beta Channels represent parallel development paths from our engineers, there may be cases where features and experiences show up in the Beta Channel first.

The desktop watermark you see at the lower right corner of your desktop is normal for these pre-release builds.
