Microsoft has released a new build of Windows 11 for Windows Insiders on the Dev and Canary Channels. Build 26052 is available for both channels as Microsoft have bumped the dev channel up to the 26xxx range matching the Canary Channel.

Microsoft say this is only a temporary position and so if you want to move a device from the Canary Channel to the Dev Channel now is a good to do so. A some point of the future Canary builds will jump up to a higher build number. So for now the Dev channel has the same features as the Canary Channel.

UPDATE: Here is my hands on video


Build 26052 Changes

Lets look at what’s new:

Windows 11 24H2

The Windows version is now displayed as 24H2 which will be main update to Windows 11 later this year.


The main change with this build is the new SUDO command. Sudo for Windows has been added to this build so you can run elevated command prompts without having to launch in a new Windows. You can read all about SUDO on Microsoft’s blog post.


There is now a way to test the difference between Default and Communication mode audio. This new utility is in the microphone properties via Settings > System > Sound. You can select the mode and record/listen to audio in both modes, allowing you to easily compare audio processing modes for applications built for the Windows ecosystem

There is a new feature in Copilot, when you copy text or images to the clipboard you get context sensitive actions to help with frequent tasks.
