Windows 11 builds 22621.450 and 22622.450 are now in Beta channel

Microsoft today released two new builds of Windows 11 22H2 to Insiders in the Beta channel. One of them supposed to have new features activated by default, and the other one has them hidden. KB5015890 delivers both builds via Windows update.

Surprisingly, both today's builds share the same set of features, with nothing new specially noted for build 22622.450. They only include general fixes and improvements.

Full build tags:

• 10.0.22622.450.ni_release_svc_prod2.220723-2016
