Is there any way to modify or delete a 'user variable' on XP Pro without login to the account?
The story is this. I got a laptop repaired but the OS (together with defective speaker and audio board) was re-installed. The problem is the Windows was installed with a username which I would like to replace. Doing through Control Panel-> User Account was successful.
However, %USERPROFILE% and %HOMEPATH% still point to the wrong folder. I managed to modify %HOMEPATH% through "Local Users and Groups" -> Users, but %USERPROFILE% remained not pointing to the new folder under C:\Documents and Settings. Then I decided to add USERPROFILE in 'user variable' to override the value used by XP. Now I can not login any more through regular reboot or safe mode. I still can login as Administrator.
How do I delete USERPROFILE that I created? From regedit, it seems I can only access Environment Variable (user variable) defined by Current User.

 

You're trying some pretty advanced stuff there. Have you thought about the basics, like deleting the previous user and creating a new user? Seems like that could solve the problem with not being able to login and deleting USERPROFILE. That is what I would try first.

 

No there actually is no way of doing it
