AnduinOS is a new Linux distribution created by a Microsoft engineer, based on Ubuntu, designed to provide a user experience similar to Windows 11. It offers both Long-Term Support (LTS) and short-term releases, with the latter featuring enhancements over its predecessor. Unlike Ubuntu, which uses Snap packages, AnduinOS utilizes Flatpak for software management, allowing access to a wider range of applications. The desktop environment closely resembles Windows 11, featuring a taskbar, Start menu, and other familiar elements, enhanced by GNOME extensions. Users can customize the taskbar and Start menu extensively, surpassing the customization options available in Windows. The integration of GNOME extensions, such as Clipboard History and Tiling Shell, further enhances productivity and user experience.
