If this is has been posted before I'm sorry, I have spent 2 hrs searching threads with success. Here goes I have a Windows 7 Home premium I lost power the other night and when the power came on the computer rebooted and asked for a password for user. None was ever set up. An admin password was never set either. Can't log in, can't do anything. Do not have a reset disk. Any help would be appreciated Thanks
