Announcing Windows 11 Insider Preview Build 25281

Hello Windows Insiders,

Today we are releasing Windows 11 Insider Preview Build 25281 to the Dev Channel.

TL;DR

• Starting with this build, we are trying out improvements to Windows Spotlight and introducing a visual update to the graphics settings page. And of course, a handful of fixes too. Details below!
• Tabs in Notepad have begun rolling out to Windows Insiders in the Dev Channel – see this blog post here.

What’s new

Improving Windows Spotlight

Starting with this build, we are beginning to try out different treatments for how Windows Spotlight looks. All treatments will continue to share existing core Windows Spotlight features such as hovering over the icon on the desktop, right-clicking on the icon on the desktop, and double-clicking on the icon on the desktop. The treatments for Spotlight will include richer UI around displaying the title and description and learning more information about the image displayed on your desktop via Spotlight. We’re also trying out different ways of switching to different pictures with previews, a full-screen experience, and a minimized experience. Insiders in the Dev Channel will see different treatments across their PCs so not everyone will see the same thing and the treatments will be shown in English only.

To enable Windows Spotlight on your PC today, right-click on your desktop and choose “Personalize” and then choose the new Spotlight theme. Additionally, you can directly enable Windows Spotlight but going to Settings > Personalization > Background and choosing the option under the “Personalize your background” dropdown.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Desktop Environment > Windows Spotlight.

Changes and Improvements

[Settings]

• Aligning with the new Windows 11 design principles, we’ve redesigned the graphics settings page under Settings > Display > Graphics to help you get to graphics configurations such as ‘GPU preference’ and ‘Auto HDR’ with greater ease. The functionality of these settings remains unchanged from prior versions of Windows, but we now have a more streamlined visual appearance. For more on all the graphics settings in Windows 11 – check out this blog post on the DirectX Blog.
• When removing a paired Bluetooth device from Settings > Bluetooth and Devices, it will no longer pop up a prompt to confirm before removing it.

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:

• .NET TFM packages for use in .NET apps as described at aka.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.
