Description of the Microsoft Windows Registry
When you start Microsoft Office XP, you are prompted to type the Product Key. After you type the Product Key, the program quits. When you start Office XP again, it prompts you to type the Product Key again.
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
Click Start, click Run, type regedit in the Open box, and then click OK.
In this example, drive is the CD drive, the MSI File is the .msi Windows Installer package for your version of Office XP (for example: Proplus.msi), and xxxxxxxxxxxxxxx is the Product Key.
