I should think this problem should be addressed at the User Accounts level.

I couldn’t find anything that would change the folder’s name there. Selecting “Rename” from the right-click menu doesn’t work either.

You have a user account for a user which doesn’t exist. Check the registry and see where it came from.

You might wanna tell me what the registry is…?

Programs——Run——regedit. Don’t mess with it if you don’t know what you’re doing. It’s far too complex for me to help you with it here. Maybe someone local can help you. At any rate is has nothing to do with the folder name.

I believe the user account, which renamed the folder in the first place, originally existed when I changed the name of the administrator account. It doesn’t work when I change that name now.

Yeah, one of the many ways in which Vista is fucked up.

Here is a list of web sites the all have to do with Vista, the second one has a forum one it also. If you type the phase“change the name of My Documents folder” in search box it will bring up alot of information for you.
