So, would i be able to, say, torrent a copy of vista home, 32-bit, which is what i have, find that key.. then do what i want with it, like, reformat and start fresh???If you're looking for your key, go to www.belarc.com. Download and run the advisor, it will give you a list of all of your keys at the bottom. If you have a Dell, the key is in BIOS and all you need is a Dell OS disc. The OS will load and search BIOS for the key. You'll be all set. You cannot use any old OS installation CD to take advantage of this though.
