Passwords and User accounts

Which User Account?

Listed as "user" under the administrator group

Is Administrator still listed?  If so, just disable the other.  You may need it later.  What is the name of your account?

Log on as Judy, but something very wrong. Have always logged on this way and Marie's computer would come up at bottom. Now, sometimes it's just computer and sometimes it's Marie's computer but I still log on as Judy. There is also a message when I click "documents" that says "C:\documents and settings\all users\documents is not accessible" It's like what I need has something else covering it up. In what runs now I can't use system restore, help and support, peoplepc. Network neighborhood says 3 computers are connected?????? When I tried to re-install peoplepc it told me I was trying to lnstall an older version over newer version already running. I think everything I need is there somewhere and I just can't get to it. This all happened when I did a repair on Outlook Express but thought if it messed up I could just use system restore. Is there any way I can get rid of all passwords and accounts and get down to one computer since that is what I thought I had. Sorry this sounds so confusing but I am one more confused person. Any help appreciated.
