I haven't found any app that doesn't run on windows server that does on win desktop. I don't game, so never tired games... Wsl on 2019 was limited to v1, but think that got to v2 on 2022... Docker works, all dev tools work... Yea, all good!
The issue is hardware. Most gaming hardware does not have server qualified drivers which may mean you can't use your hardware. Issues normally with WiFi cards and GPUs, most other things will work. No chance of running Windows Server on a laptop.
The qualification is to prevent random crashes; it's not really needed, but it is hard to impossible to disable last I checked.
Never had an issue with drivers... Was running nvidia cards and the standard nvidia drivers worked without issue... Also did manage to run win2003 on a laptop at one stage... Can't remember if drivers for wifi worked... The machine was hard wired in...
I've had wifi, bluetooth, and AMD GPUs fail to work, as well as integrated Intel GPUs. This may just be a 2019+ problem. 2008 might run, I haven't checked.
You may also find power management drivers don't install.
