apparently wsl 2 enabled option to run gui apps too so I would imagine desktop or wm would work too, but I don't think it would be possible to enable super key for those without windows registering it too. this is just my speculation though. but traditionally people use it to run linux cli applications etc.

at least my classmates have been using it for classes that require usage of linux. I have never touched it myself since I converted to the church of linux before wsl was a thing

WSL is just a well integrated VM running Linux. It's mainly intended for CLI tools, but there's nothing preventing you from e.g. running an X server and having programs appear in the Windows "window manager".

The super key is largely inaccessible though. It's tied very deeply into Windows, which is still the one talking to the keyboard.

So I have to use a windows machine for work. I can't tell you how awsome wsl is. You can use any Linux package on wsl. If you are crasy enough you can even run desktop environments like xfce. All this with nearly native speed.

Of cource things links a KVM aren't possible but nothing is nicer to just type wsl into your terminal and have your Linux distro of choice ready to go

Run containers, mount both system volumes without significant write performance, wm, and networking is simple. No idea about super.

I have to use MS suite and this is far than osx bastardized unix and for most of my day to day technical work its essentially Linux built natively into Windows in practice.
