I’m looking to format and reintal my OS on my computer but I don’t remember which CD key I used. Is there a program I can use to do this? I remember crossing one a while ago but I don’t recall the name or where I got it. Any ideas?

This [keyfinder](http://www.michaelstevenstech.com/keyfinder.exe) application should do the trick.
