Wallpaper++ (previously known as Dynamic Desktop and Codename: Dreamscene) lets you set your wallpaper to a video or html file, kinda like Windows Dreamscene and Active Desktop combined.
✔ Pictures (For some reason)
✔ Videos
✔* HTML (Implementation is barebones. Really only meant for basic html and css.)
✔ Gifs
Windows 7 SP1 or newer
.NET 4.7.2 or newer (Should come with Windows 10)
Windows Aero enabled
Windows Media Player (Should come with Windows)
🟡 Windows 11 / Server 2025 (Only works with pre-24H2 version of Windows 11. 24H2 and later will not work without modifications to explorer.)
✔ Windows 10 / Server (2016/2019/2022)
✔ Windows 8.x / Server 2012
✔ Windows 7 (With SP1)
✔ Windows Server 2008 R2 (With SP1) (Windows Aero may have to be installed if not already) (Untested, but I assume it works)
❌ Windows Vista / Windows Server 2008 and before
❓ Windows Betas / Insider Builds (They might work, but compatibilty isn't guaranteed)
