Keyboard inputs are delayed and buffer for some reason, and while buffering the program can't be switched out of and freezes.
Trackpad won't work either, so I plugged in an extra mouse.
Microsoft site says I need to download and install something called an NT4 Terminal Server but it "failed to install" with no additional details.
Edit: Just turned off a whole bunch of processes and seems to work fine now, though the track pad still wont work.
