Windows 10, since Anniversary Update, has a new feature (not enabled by default) where you can have an entire (Ubuntu-based) Linux user space running natively (no VM) on your Windows machine, it's called Windows Subsystem for Linux: https://blogs.msdn.microsoft.com/wsl/2016/04/22/windows-subs...

Windows 10 has an entire Linux subsystem now. They've implemented the posix APIs and there are other blog posts where people have gotten things like i3 running natively in Windows. It's only in the preview builds and you have to specifically enable it.
