[Windows] Activate and configure Windows Subsystem for Linux

Windows 10 introduced an update that adds a very cool feature: Windows Subsystem for Linux. If you are a fan of Cygwin, or similar tools, you will greatly like this feature as well.

Setup could be a bit more straightforward, but still not a big issue:

1. Enable Windows Subsystem for Linux as a Windows feature from Control Panel > Programs and Features > Turn Windows features on or off
2. Reboot
3. Make sure LxssManager service is running
4. Install a Linux distro from Windows store, search for "WSL" and pick the one you prefer, for example Alpine or Ubuntu, if no distro is installed, you get an error instead:

Windows Subsystem for Linux has no installed distributions. Distributions can be installed by visiting the Windows Store: https://aka.ms/wslstore Press any key to continue...

And going to that link brings you nowhere.. so just install it yourself from the store.

After the installation is completed (might ask you to setup a user and password), you can open any command prompt and type wsl to launch it.

Be careful, that command was different in the past: lxrun or bash and there are apparently 2 versions of WSL as well, use whatever makes it run for you
