Microsoft is reintroducing the DreamScene feature in the latest builds of Windows 11, allowing users to set video wallpapers using video files such as MP4 or MKV. This feature was previously available in Windows Vista and has been requested by the Windows community. DreamScene will enable videos to play seamlessly on the desktop, similar to the third-party application Wallpaper Engine, which is popular among users. Microsoft initially supported video wallpapers in Windows Vista's Ultimate version but discontinued it with Windows 7. The company has been experimenting with dynamic animated wallpapers for Windows 11, although these did not launch in the final release version of the operating system. The return of DreamScene may reduce the need for third-party solutions like Wallpaper Engine.
