The Windows Subsystem Linux (WSL), which lets you run Linux programs on a Windows box, has seen some serious love from Microsoft as its engineers attempt to demonstrate their commitment to open source and Linux.
As such, the next version of WSL, version 2.0, will, fingers crossed, contains a Linux 4.19 kernel within a so-called utility virtual machine, which will run Linux programs. This is due to arrive "later this year," via Insider builds in June, and the Windows store.
Just stop and think about that for a second. It means when you come to run a program, the Windows kernel will either interface with it directly if it's a Windows application, or allow the Linux kernel to manage it if it's a Linux application. Now you can run Linux software truly natively on the world's largest desktop OS platform, developed by a company that once declared Linux "a cancer."
