I have a laptop that was being used by a friend and was part of his domain at his office. He left his job and switched from a domain to a workgroup. Originally the machine used his username, and password to connect to xxxxx domain and log him into windows. He went to my computer>properties> computername and changed from domain to workgroup and renamed his computer. Now He can't log onto windows and he does not know an administrator password for the local machine. He has several documents on the machine that he needs to recover. How can I log in on this machine without losing anything?
