i'm taking a stab-in-the-dark with this one, but i would guess by the name that it has to do with a fingerprint reader. i don't know, obviously, if yours has a fingerprint reader, but i state this because, at least in my case, the computer company may have had the software integrated into windows for a string of models in the same line. to give you an example, i have an acer aspire 5100 laptop and mine has preinstalled bluetooth drivers and has the bluetooth service too. but, my laptop does not have any bluetooth hardware! i would assume that the next model up, would have bluetooth hardware and every other spec the same as my model, so acer would save time and money by having a vista image they could deploy to many computers at the same time.
my two cents
