Can you tell what you mean with "the Windows 7 limited administration thing"? And do you use an administrator account when you do this?

I'm trying to delete a folder in the C: drive and to do that I have to change the ownership of the folder because of the Windows 7 limited administration thing. I went to the folder in question, clicked on Properties, clicked on Security, went to Advanced, clicked on Owner, went to Edit, and tried to change the owner both to the Administrators and to my personal user, but both said "Unable to set new owner on FILE" Access is denied. On other threads I have never found anyone run into this, can someone help me understand what's going on?
