BBez, I have got a similar thing in XP. Mine appeared after the OS had to be reinstalled, on the same drive unpartioned to allow the transfer of files. Instead of ...Windows.. I have WinXP which was the name given to the, to be replacement OS. But it has left what appear to be duplications and these extra WinXP files. As you say they don't seem to make much difference and I'm loath to delete them.
