This is the first time this has happened. I had a power outage and my computer turned off. I restarted it and it's now asking me for a login and password, problem is I've never set up a login or password. When I try to login it gives me an error "THE SYSTEM CANNOT LOG YOU IN BECAUSE THE DOMAIN HOME-PC IS NOT AVAILABLE". But it doesn't give me the option to change the domain. I'm stuck at the windows login screen. I restarted the computer 3 times.
