If for some reason, legal reason that is that you have to reinstall your Windows 2000 or higher operating system or Office 2003 or higher software and lost your installation key, there is a way to find it. You can use the Magic Jellybean Keyfinder. It's an executable file that will find your installation key within the registry.
For Windows 95, 98 and ME you can find the key within the registry but for later versions of Windows the key is encrypted. The Keyfinder will go into the registry, find the key and let you know what it is.
To get the program you can download it from the Magic Jellybean Software website. Just download it to your desktop and double click the keyfinder.exe file and that's it!
