Question about Microsoft Windows XP Professional
This usually means that the key (serial) you have entered for your operating system is invalid (pirated, stolen, keygenned).
If you have a legitimate key you should be able to enter it to validate your copy of Windows XP Professional.
If you do not own a key you can buy one from Microsoft via their Genuine Windows program.
Hope this helps,
