I recently installed windows XP on my friends new Hard Drive I also installed. But she is getting an unusual message when she tries to log out so she can shut down. It is coming up with the message other users are logged into windows and by shutting down it could cause users to lose data. She is the only user in her home no one else lives there. Have you ever encountered this and what can I do to fix this problem? She has Symantec Anti Virus installed and has windows security.
