experimental shells
About this tag
The experimental shells tag on WindowsForum.com covers user discussions about alternative desktop environments that replace or significantly modify the standard Windows shell. A key example is Seelen UI, a web-first shell built on Microsoft's WebView2 that replaces the taskbar, start menu, and other elements with a floating dock, top menu bar, and custom flyouts. These projects are community-driven and aim to reimagine the Windows 11 interface, offering a different user experience while still running on top of Windows. The tag focuses on non-Microsoft shells that are in development or testing phases, often with a focus on customization and modern web technologies.
Seelen UI arrives like a skin you can live inside — not just a theme or taskbar tweak, but a full, web‑powered desktop environment that can make Windows 11 feel like an entirely different operating system.
