I'm doing a hard drive upgrade and it might ask me for the product key again. How can I find it?

Either the sticker that came with your machine and/or on the media case.

You can also try Magic Jelly Bean Keyfinder for a software way.

Windows 7 comes on DVDs. CDs as a distribution means for Windows Operating Systems are a thing from the past. :) – Molly7244 Dec 26 '09 at 17:58

Magic Jelly Bean is awesome. It instantly shows me the product key for Windows 7 as well as the other Microsoft products installed on my system. – Phenom Dec 27 '09 at 1:21

Belarc Advisor.

Download, install, run it, then it opens a page in your web browser displaying all kinds of facts and statistics about your PC...near the bottom, it has all the product keys, etc for all the install software, and, of course, the operating system...Hope that helps!
