Microsoft never sleeps. In addition to its steady releases of major and minor updates to the current version of Windows 10, 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.
Although Windows Insiders can choose to receive Windows 11 preview builds in one of four channels — the Canary, Dev, Beta, or Release Preview Channel — Microsoft currently offers Windows 10 Insider previews in the Beta and Release Preview Channels only.
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. The Beta Channel previews features that are a little further out.
Below you’ll find information about recent Windows 10 preview builds. For each build, we’ve included the date of its release, which Insider channel it was released to, a summary of what’s in the build, and a link to Microsoft’s announcement about it.
Note: If you’re looking for information about updates being rolled out to all Windows 10 users, not previews for Windows Insiders, see “Windows 10: A guide to the updates.”
