If you’ve purchased a personal computer within the last few years, chances are that the PC manufacture packaged in a system recovery disk. System recovery disks are useful if you need to format the hard drives and reinstall your operating system. Before you attempt a format of your hard drives, you should make sure that you’ve got your Windows Product Key handy. It may be on a sticker on the side of your computer, or on the Windows OS DVD sleeve, which may or may not have been packaged with your system. If you do not have your Product Key, then you may have to retrieve it from your system registry, otherwise you may not be able to re-install Windows XP. You can download a very cool application called ‘Magical Jelly Bean Keyfinder’ that will help you retrieve your Product Key .

Magical Jelly Bean Keyfinder is easy to use, and once launched will provide you with your Windows Product Key as well as the Product Key for other programs installed in your computer.
