I have been using SIW for years to determine what hardware a particular computer has....an invaluable aid when working on a customers computer. This would also come in handy if you were considering buying a used or reconditioned computer. Now there is, IMO, a better one available from the makers of the old standby Crap Cleaner...Piriform, called Speccy. It's free.
