Why do I need to change my windows key?
If you try to install Microsoft Windows XP Service Pack 1 (SP1), you may receive the following error message: The Product Key used to install Windows is invalid. Please contact your system administrator or retailer immediately to obtain a valid Product Key. You may also contact Microsoft Corporation’s Anti-Piracy Team by emailing piracy[email protected] if you think you have purchased pirated Microsoft software. Please be assured that any personal information you send to the Microsoft Anti-Piracy Team will be kept in strict confidence.
This issue may occur if the product key that you are using to install Windows XP matches a product key that Microsoft has determined to not be valid. These two product keys create a product ID that matches one of the following product IDs (where X is any numeric value):
