Ok so i have a toshiba laptop that i bought about 2-3 yrs ago that im going to be selling so i want to reformat and start fresh for the next owner...anyways the windows sticker on the bottom has since worn off and i can only see the last 8 characters of the vista key...so i downloaded two different "key recovery" programs and they both found a key on this laptop for vista, and athough the programs keys match, they don't match at all with the original key...i have never reformatted this laptop before and i don't recall ever getting a backup disc with the laptop or if i did where it would have gone...so my question is, is the key that is on the laptop that the programs found going to work when i try to reload windows vista again? does it matter that they don't match the orginal key on the bottom?
