The Windows 11 2022 Update has been released, but behind the scenes, Microsoft is constantly working to improve the newest version of Windows. The company frequently rolls out public preview builds to members of its Windows Insider Program, allowing them to test out — and even help shape — upcoming features.

The Windows Insider program is divided into four channels:

[ How to preview and deploy Windows 10 and 11 updates ]
The Canary Channel (new in March 2023) is where platform changes (such as major updates to the Windows kernel and new APIs) are previewed. These changes are not tied to a particular Windows release and may never ship at all. Little documentation is provided, and builds are likely to be very unstable. This channel is best for highly technical users.
The Dev Channel is where new features are introduced for initial testing, regardless of which Windows release they’ll eventually end up in. This channel is best for technical users and developers and builds in it may be unstable and buggy.
In the Beta Channel, you’ll get more polished features that will be deployed in the next major Windows release. This channel is best for early adopters, and Microsoft says your feedback in this channel will have the most impact.
The Release Preview Channel typically doesn’t see action until shortly before a new feature update is rolled out. It’s meant for final testing of an upcoming release and is best for those who want the most stable builds.
