Announcing Windows 11 Insider Preview Build 25290

UPDATE 2/7: We are starting to roll out Cumulative Update Build 25290.1010 (KB50234461). This update does not include anything new and is designed to test our servicing pipeline for builds in the Dev Channel.

Hello Windows Insiders,

Today we are releasing Windows 11 Insider Preview Build 25290 to the Dev Channel.

TL;DR

• This build is available for Arm64 devices as the known issue that resulted in not releasing Build 25284 to Arm64 last week has been fixed.
• We have more new widgets for Insiders in the Dev Channel to try!
• This build includes a set of general improvements and fixes.

What’s new

New Widgets: Spotify and Phone Link

Last week,we promoted a preview of the widget for the Messenger app. Spotify and Phone Link are now rolling out preview versions of their widgets as well. To give them a try, go to the widgets collection in the Microsoft Store and update to the latest version of the apps. 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 widgets.

As you give these 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.

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. If you’re interested in developing a widget, watch our latest tutorial video (see the original blog post below).

Changes and Improvements

[Start menu]

• Back in October with Build 25227, we started trying out a small change to the Start menu where some Insiders saw badging on their user profile notifying them that certain actions need to be taken. We concluded that initial exploration in November. Starting today, we are starting a new exploration of badging on the Start menu with two new treatments that some Insiders in the Dev Channel will see. If you see one of these treatments, give us feedback on what you think. As a reminder, it is normal for us to try out different concepts in the Dev Channel to get feedback.

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:

• .NET TFM packages for use in .NET apps as described at ms/windowsinsidersdk
• C++ packages for Win32 headers and libs per architecture
• BuildTools package when you just need tools like MakeAppx.exe, MakePri.exe, and SignTool.exe

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.
