If you're preparing to reinstall Windows XP you will need to locate your copy of the Windows XP product key - also known as the CD key.

If you've lost your product key, it's located in the registry but is encrypted and not readable, making finding it difficult.

The key was not encrypted in previous versions of Windows like Windows 98.
