Microsoft has started testing the ability to use video wallpapers on Windows 11. The feature has been spotted in the latest builds of Windows 11, and allows you to set video files like MP4 or MKV as your desktop wallpaper background.

The videos play every time you view your desktop, much like third-party solutions like Wallpaper Engine. Microsoft previously supported video wallpapers in Windows Vista as a DreamScene feature for the Ultimate version of the operating system, but DreamScene was dropped from Windows 7.

Video wallpapers are a highly requested feature for Windows users, and Wallpaper Engine is regularly in the top 10 most played apps and games list on Steam simply because of how many people have the app installed and running.

Microsoft had been testing dynamic animated wallpapers for Windows 11 for years, and a former design even revealed exactly what they looked like earlier this year. These dynamic wallpapers were supposed to ship in 2023, but never made it into the release version of Windows 11.
