Transform Windows 10/11 into the OS you've always wanted with Seelen UI


Windows 10 and Windows 11 are functional but a bit unexciting, with limited customization options. If you’ve ever wished you could make Windows look and work better, the good news is that Seelen UI has you covered.
This free tool reimagines what a Windows desktop can be, giving users the power to break free from Microsoft’s frustrating limitations -- and it’s just been updated to offer even more features and improvements.

The user-friendly Seelen UI lets you customize your desktop, adjust themes, taskbar layouts, and icons with just a few clicks. The Tiling Windows Manager automatically arranges windows for efficient multitasking. There’s also an integrated media module compatible with most music players, and an app launcher inspired by Rofi that offers a simple way to run apps and commands.
Seelen UI requires the WebView runtime, which is pre-installed on Windows 11 and included with the setup for Windows 10. Microsoft Edge is also required for the program to function properly.
