Windows 11 Beta Build 26220.8474 (25H2): What's New?

The Windows Insider Beta Channel has been rebooted! For its 25H2 path, build 26220.8474 is now available. The revamped Insider Settings page is now available, and starting now gradual rollouts are gone, meaning you'll get announced features immediately after updating.

With Beta also moving back to its intended role of previewing changes for the next drop instead of rough, early experimental changes, this build is a bit smaller. Fluid Dictation features in voice access and voice typing now support extra languages, and there are some reliability improvements for properties dialogs and DISM.
