Windows 11 Tests Native Video Wallpapers in Hidden Insider Builds

The unannounced test revives Vista-era DreamScene-style backgrounds discovered by community testers.

Overview

  • X user @phantomofearth surfaced the setting in recent Dev and Beta previews, citing build 26x20.6690.
  • The feature lets users set video files as desktop backgrounds, with playback only when the desktop is in view.
  • Supported formats reported so far include MP4, MOV, AVI, WMV, M4V and MKV.
  • Microsoft has not announced the capability or provided a release timeline for general availability.
  • Native support could reduce reliance on third-party tools like Wallpaper Engine and Lively Wallpaper, though those apps currently offer more advanced options.
