Windows: How to reset the administrator password?
I have been given an ex-business laptop to clean up for home use. The laptop was previously on a business domain, but for home use I don't want it to be on a domain. The laptop is running Windows XP professional.
I changed the computer properties so that it doesn't log onto a domain anymore, but unfortunately I restarted the computer before I added a new user. Now, I am faced with a logon screen (not the welcome screen), and I know one of the usernames, but not the password. I also have no idea what the Administrator password is on the local computer.
I am unable to log back onto the original domain (where I have administrator privileges), because the local login screen does not present any options for specifying the domain. I also can't seem to change it back to a domain computer, since I have to login first (which I can't do). Rebooting in safe mode still asked me to login, so that's no help.
How would I go either getting this machine to log back onto a domain, or finding some way to log back in with Power User / Administrator privileges?
