The news was announced at Microsoft's Build 2017 conference in Seattle. Enthusiasts and developers will be able to install Ubuntu, SUSE Linux, and Fedora directly via the Windows Store, making it easier than ever to run Linux software on any Windows 10 device.
The Linux distros will run in a virtualized environment, and will offer the same command-line utilities as offered by full installations. The news also means the new education-focused Windows 10S, which can exclusively run Windows Store apps, will be able to execute Linux code.
