Windows 7: Renaming a locked User Account folder

Hi, I've recently picked up a new hard drive from a buddy of mine.
I've managed to change my computer name and user account name.
However, the user folder in "My Computer -> Local Disk C: -> Users" is locked, and I am unable to change the name.
It doesn't cause any problems, I just want to find a way to change it if its possible.
As well, I've also set permissions, but it only allows me to access the files, which is not the problem, since I only want to change the name of the User Account Folder.

You can't change the name associated with an account. Doing so would make the account useless.

You need to create a new account with the name you want, then copy everything you want from the old one to the new one. Delete the old one once your satisfied all is well.

In your case, you will need to rename the existing account back to it;s original name or some name other than what you want to call the new one as you can't have two with the same name.
