Windows OS is bringing back live wallpapers, reminiscent of the Windows Vista era. Originally known as DreamScene , this feature enabled video files, such as MP4 or MKV, to be used as live wallpapers on Windows desktop PCs. Microsoft is currently testing this feature again, as noted by @phantomofearth on X. In the latest Windows 11 Dev/Beta build 26x20.6690, there is a hidden option that lets you use video files as live wallpapers. Microsoft is also testing support for external files, which means we might see the company include a selection of customized live wallpapers in the next Windows 11 update.

To enable this feature, you need to be a part of the Windows Insider program. Once you become a part of this feature-preview program, you need to enable feature ID 57645315 and restart your explorer.exe, so Windows can apply it. However, the timeline for this feature is uncertain, and it might be part of next year's major updates. As of now, no significant features have been added this year. Microsoft isn't aiming for more under-the-hood changes for the 25H2 update, nor a visual makeover that prior updates were usually known for. Instead, the updates are primarily focused on security and are delivered as an enablement package . For changes like this, we assume Microsoft needs more bug testing before rolling out the feature to stable channels.
