Windows 11 Insider Canary Build 25375.1

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 25375 to the Canary Channel.

REMINDER: As builds released to the Canary Channel are “hot off the presses,” we will offer limited documentation for builds flighted to the Canary Channel (no known issues for example), but we will not publish a blog post for every flight – only when new features are available in a build. And like the previous Canary Channel build, this build has a few new features and changes to document.

What’s new in Build 25375

Support for Microsoft Endpoint DLP on Windows on Arm (Arm64) builds

You can now extend Microsoft Endpoint Data Loss Prevention (DLP) policies and actions to endpoints running Windows on Arm (Arm64) which allows you to detect and protect sensitive data in files part of your digital ecosystem. This enables you to introduce policy controls for scenarios such as when an information worker using a Windows endpoint powered by Arm chipset from accessing sensitive files and trying an egress action such as copying to a USB, or copy to clipboard, notepad, etc.

As part of your DLP Policy definition, you can leverage the current conditions and actions that are already available for use and there is no additional setting involved.

Ensure your ARM64 endpoints are onboarded to Microsoft Endpoint DLP by using any of our supported onboarding methods.

About the Canary Channel

The Canary Channel is the place to preview platform changes that require longer-lead time before getting released to customers. Some examples of this include major changes to the Windows kernel, new APIs, etc. Builds that we release to the Canary Channel should not be seen as matched to any specific release of Windows and some of the changes we try out in the Canary Channel will never ship, and others could show up in future Windows releases when they’re ready.

The builds that will be flighted to the Canary Channel are “hot off the presses,” flighting very soon after they are built, which means very little validation and documentation will be done before they are offered to Insiders. These builds could include major issues that could result in not being able to use your PC correctly or even in some rare cases require you to reinstall Windows. We will offer limited documentation for the Canary Channel, but we will not publish a blog post for every flight – only when new features are available in a build.

Our Canary Channel won’t receive daily builds; however, we may ramp up releasing builds more frequently in the future.

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