Hi, I am Dave, I will help you with this.
A Windows reset would usually complete in 1 - 2 hours, how long has it been stuck at the 'Restarting' screen?
if that is stuck for more than 30 minutes, you have no other option, press and hold the power button on the case of your PC for 5 - 10 seconds to perform as hard shut down, then wait a few seconds and start your PC again, the reset should then either continue to completion or roll back.
