Btw all this talk of rendering the "old" OS key useless is a bit misleading. Your old key is still valid for that OS and you could reinstall with just that OS on the computer. You cannot upgrade to 8 and then try and use your old OS key on a different machine. Think of it like a DLC. Just because you added dawn guard to skyrim doesn't mean you can give skyrim to a friend to also install. But if you didn't like dawn guard you can reinstall just skyrim. (a funny comparison but you get the idea)
People were making it out to sound like if you use the upgrade to 8 option you could never go back to the old OS with the old license.
