I should have stated, the machine was just serviced by samsung (new hard drive, only 1+month old computer go figure).
when replacing hard drive, they did something like take an image of the old drive to preserve microsoft signature installation of windows 7 (I had purchased the computer from microsoft retail store, and understand this edition to be much faster). so, could it be a legacy of that image perhaps when I first turned-on the brand new machine a month ago, and could it not be there now? if so, could I just delete it (instead of adding the missing folders to trick windows backup)?
of course, one is always afraid to delete something 'administrator', but as stated I already have set-up an admin account under my own name so then does the 'administrator' user become unnecessary, I wonder?
