Change Windows key with Script

If 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:
• They remove the hyphen characters (-) from the five-part alphanumeric product key.
• They create an instance of the win32_WindowsProductActivation class.
• They call the SetProductKey method with the new volume licensing product key.
You can create a batch file or a cmd file that uses either of the following sample scripts, together with the new product key as an argument. You can deploy it as part of a startup script or run it from the command line to change the product key on a single computer.
