Microsoft announced that Linux GUI Apps will run directly on Windows 10 during the Microsoft Build 2021 event, which began yesterday.
Previously, Windows 10 could use Windows Subsystem for Linux, or a Linux distro via WSL, via the command line, but now it can also run GUI apps.
It was first tested with the Windows 10 Preview build, which was released in April, and Microsoft made it available to everyone during the build event, which began yesterday.
This allows developers, particularly app developers, to test their apps in a different Linux environment and run them on any Linux distro from Windows 10 onwards.
This has previously necessitated the use of a different computer or virtual machine, but with this feature, Microsoft should be able to keep its users on the Windows 10 operating system.
