I logged in to my Microsoft account in an attempt to download a game from the store.
The next morning when I went to use my laptop the password it required was my Microsoft one and not my regular password.
I went to the start menu and selected the option of signing out of my account.
Since then (38 hours now) my screen is stuck on a blue screen saying "signing out" with a circle thing spinning.
I've tried forcing a shutdown, but all pressing the power button does is put it to sleep. When I turn it back on I'm still in the same place with that screen. No other keys seem to respond.
