How to change a user name in the Windows System Folder

[darla]

Ok I have Windows XP Pro and all my documents etc.. are under the name None-1 and I would like to change it. How do I change it??

When I right click on Start select explore go to my C drive and under documents and settings it lists the users (this computer is shared between myself and my 2 kids) so it does list my kids' names and where mine should be it says None-1.
I tried to rename that but it won't allow it because its a windows system folder.

My user log in at start up does show my name but in the documents and settings the user says None-1. So, how do I change None-1 to my name Darla ??

Thanks in advance for any help anyone can give me..

I`d bet that Darla doesn`t have administrative privileges. One of the other users who does can put you in the admin group so you can change it.
