Warning The steps in the article are effective only on Volume License media. If you try these steps on OEM media or on retail media, you will not change the product key. When you install Windows XP or Windows Server 2003, the media must match the product key. That is, the channel (MSDN, retail, OEM, Volume License, and so on), the SKU (Windows XP Professional, Windows XP Home Edition, and so on), and the language (English, French, and so on) must match between the product key and the media. This is necessary so that you can successfully enter the product key. If the installation media does not match the product key, you receive the following error message:
If you use a "leaked" product key (a product key that is known to be available to the public) to deploy Windows XP across multiple computers (a Volume Licensing installation), you might be unable to install Windows XP Service Pack 1 (SP1) and later versions of Windows XP, or automatically obtain updates from the Windows Update Web site. For example, you might receive the following error message when you install Windows XP SP1 and later versions of Windows XP:
Product Key is invalid.

Steps to change the volume licensing product keyThis article describes two methods for how to change the Windows XP product key after a Volume Licensing installation to resolve the issue. One method uses the Windows Activation Wizard graphical user interface (GUI) and the other method uses a Windows Management Instrumentation (WMI) script. The Activation Wizard method is easier. However, if you must change the product key for multiple computers, the script method is more suitable.
Method 1: Use the Activation WizardImportant This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

Note We recommend that you run System Restore to create a new restore point before you follow these steps.
Reactivate Windows and add new product key
Method 2: Use a scriptIf you must change the product key for multiple computers, we recommend this method. You can create a WMI script that changes the volume licensing product key, and then deploy this script in a startup script.
The sample ChangeVLKey2600.vbs script and the sample ChangeVLKeySP1 script that are described in this section use the new volume licensing key that you want to enter as a single argument. It is in a five-part alphanumeric form.
We recommend that you use the ChangeVLKey2600.vbs script on Windows XP-based computers that are not running Windows XP SP1 and later versions of Windows XP and that you use the ChangeVLKeySP1.vbs script on Windows XP-based computers that are running Windows XP SP1 and later versions of Windows XP. These scripts perform the following functions:

The following example shows how to use the ChangeVLKeySP1.vbs script from a command line:
