WSL2 is "fine". It has some performance issues when accessing files on the windows side of things from sick

On a technical level it's a Linux VM running containers for Distributions that get some mounts and for WSLg a directx video device.

WSLg also provides an X server, Wayland compositor and a Pulse server so most gui apps "just work".

Good way to start learning or get a taste for things, and easier than a VM to get started.
