There are two methods people can apply to change the Product Key with the Volume Licensing media after installation. The first method is to use the Windows Activation Wizard (GUI), and the second method is to use the command in Windows Management Instrumentation (WMI).
The method used by the Windows Activation Wizard is simpler than using the command line. Use this method in case you have only a few computers that need to change the Product Key. But in case you need to change the Windows Product Key for multiple computers, the command method is the most efficient method.
You do the following:
Click Start | Run.
In the Open box, enter Regedit and click OK.
Then the Registry Editor window will pop up. In the left pane, go to the following key: HKEY_LOCAL_MACHINE \ Software \ Microsoft \ WindowsNT \ Current Version \ WPAEvents
In the right pane, right-click on OOBETimer and select Modify.
Change at least some of this value to deactivate Windows.
Click Start | Run.
In the Open box, type the following command, and then click OK:% systemroot% \ system32 \ oobe \ msoobe.exe / a
Click on Yes, I want to contact you.
Click Change Product Key.
Enter the new Product Key in the New key boxes and click Update. If you return to the previous window, click Remind me later and then reboot the system.
Repeat steps 6 and 7 to re-enable Windows. When successful, you will receive the message Windows is already activated. Click OK to exit the wizard.
Install SP1 for Windows XP.
You can create a WMI script to change the VLK, then deploy this script in a boot script. The sample scripts ChangeVLKey2600.vbs and ChangeVLKeySP1.vbs described in this section will use a new VLK that you want to import. Microsoft recommends that you use the ChangeVLKey2600.vbs script for Windows XP product key-based computers that do not use SP1 and that use the ChangeVLKeySP1.vbs script on computers that are running Windows XP SP1. These two scripts perform the following functions:
Remove the dash (-) from the Product Key, which consists of five parts.
Create a win32_WindowsProductActivation class. They will call the SetProductKey function with the new VLK.
You can create a batch file or a CMD file using one of the sample scripts with the new Product Key as an argument, then deploy it as part of a startup script or run it from the command line instead. Change Product Key on a computer.
