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
