Microsoft has released a tool to help Linux aficionados port their favorite Linux distro to run on Windows Subsystem for Linux (WSL) The tool is a Windows 10 component that sideloads Linux distros on modern Windows 10 PCs. Microsoft has already released official images for Ubuntu, SUSE, Kali Linux, and SUSE Linux, all of which are available via the official Windows Store. The project, open-sourced on GitHub, is a reference implementation of how Linux OS projects (or mundane Linux users alike) could port to run inside WSL.
