Too many Adminstrative Folders...how do I delete

After undating to Service Pak 2, I noticed that I have several Adminstrative
folders in my Documents and Settings folder.
Adminstartor (2/16/05)
Adminstartor, valued-B8142DE8 (2/19/05)
Adminstartor, valued-B8142DE8.00 (2/21/05)
Folders contained in these files are 2005 and older. There are no current
files to be found.
I also, have an All Users folder and a User Folder that contain similar
folders and current files.

Can I delete the Adminstrator Folders? If so how?
