Hi All, ........... In the process of setting up my daughter's new Windows 7 computer, I had occasion to use Keyfinder, the Magical Jelly Bean program. The computer has no CD/DVDs and has the operating system pre-installed. The Jelly Bean program produced a result of the CD Key . When I compared this result with the Microsoft label on the computer case, what is listed there is called the Product Key and is completely different from the CD Key. Which is more important to be used in future Key requirements? In the past I seem to recall that I used the results of the Jelly Bean program when doing, for example, an operating system Repair. Can someone explain these differences. Thank you.
