The Windows Subsystem for Linux GUI (WSLg) enables support for running Linux GUI applications on Windows in a fully integrated desktop experience. WSLg provides an integrated experience for developers, scientists, and enthusiasts who need to run Windows and Linux applications side by side. The system uses a combination of technologies, including Weston, FreeRDP, and PulseAudio, to enable seamless interaction between Linux GUI applications and the Windows desktop. WSLg is available on both Windows 11 and Windows 10, with some limitations on older systems.
