Microsoft has announced two new Linux distributions for Windows 10 Subsystem for Linux (WSL), including the first paid-for Linux distro called WLinux. WLinux is a Debian-based distro available for $19.99 from Microsoft Store. The company also announced Ubuntu 18.04, which will be available through the Microsoft Store, as well.

While Windows 10 October 2018 Update is still to recover from the data loss bugs and its rollout process is yet to be restarted, Microsoft has today shared how the latest Windows 10 version 1809 will bring more support for Linux distros through the WSL. WSL enables Windows 10 to run various GNU/Linux distros inside the operating system as apps, offering access to Ubuntu, openSUSE, Debian, Kali Linux, and others.
