How can I change the volume licensing product key on a Windows XP SP1-Based Computer?

How can I change the volume licensing product key on a Windows XP SP1-Based Computer?

Because of changes in Windows XP Service Pack 1 (SP1), Windows XP-based computers that use a leaked product key that is known to be available to the general public may not be able to install SP1 or automatically obtain updates from the Windows Update Web site. For an easy and quick method of obtaining your own CD Key please read Quickly Retrieve Windows CD Key.

For example, you may experience the symptoms that are described in the following Microsoft Knowledge Base article when you install SP1:

326904 Error Message: The Product Key Used to Install Windows Is Invalid

There are two (legal) methods that you can use to change the product key with volume licensing media after installation. You can use either the Windows Activation Wizard graphical user interface (GUI) or a Windows Management Instrumentation (WMI) script.

Say Goodbye to Traditional PC Lifecycle Management

Traditional IT tools, including Microsoft SCCM, Ghost Solution Suite, and KACE, often require considerable custom configurations by T3 technicians (an expensive and often elusive IT resource) to enable management of a hybrid onsite + remote workforce. In many cases, even with the best resources, organizations are finding that these on-premise tools simply cannot support remote endpoints consistently and reliably due to infrastructure limitations.

The easier method to use is the Use the Activation Wizard method. Use this method when you only have a few computers on which to change the product key. The Use a Script method is best when you have a number of computers on which you have to change the product key.

Legal Note: Make sure you understand that this method is indeed legal. This is NO crack, NO hack, there is nothing illegal with this article. I will not, however, encourage any reader to use an illegally obtained CD Key. What you do in your own house/office is your own business, and I cannot and will not be held responsible for your actions.

Method #1: Use the Activation Wizard

If you have only a few volume licensing product keys to change, you can use the Activation Wizard.

Warning!This document contains instructions for editing the registry. If you make any error while editing the registry, you can potentially cause Windows to fail or be unable to boot, requiring you to reinstall Windows. Edit the registry at your own risk. Always back up the registry before making any changes. If you do not feel comfortable editing the registry, do not attempt these instructions. Instead, seek the help of a trained computer specialist.

Note: Microsoft recommends that you run System Restore to create a new restore point before you complete the following steps:

  1. Click Start, and then click Run.
  2. In the Open box, type Regedit, and then click OK.
  3. In the left pane, locate and then click the following registry key:
  4. In the right pane, right-click OOBETimer, and then click Modify.
  5. Change at least one digit of this value to deactivate Windows.
  6. Click Start, and then click Run.
  7. In the Open box, type the following command, and then click OK.
  8. Click Yes, I want to telephone a customer service representative to activate Windows, and then click Next.
  9. Click Change Product key.
  10. Type the new product key in the New key boxes, and then click Update. If you are returned to the previous window, click Remind me later, and then restart the computer.
  11. Repeat steps 6 and 7 to verify that Windows is activated. You receive the following message:Windows is already activated. Click OK to exit.
  12. Click OK.
  13. Install SP1 for Windows XP.

If you cannot restart Windows after you install SP1, press F8 when you restart the computer, select Last Known Good Configuration, and then repeat this procedure.

Method #2: Use a Script

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, in its five-part alphanumeric form, as a single argument. Microsoft recommends that you use the ChangeVLKey2600.vbs script on Windows XP-based computers that are not running SP1 and that you use the ChangeVLKeySP1.vbs script on Windows XP-based computers that are running SP1. These scripts perform the following functions:

  1. They remove the hyphen characters (-) from the five-part alphanumeric product key.
  2. 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, and either deploy it as part of a startup script or run it from the command line to change the product key on a single computer.

VOL_PROD_KEY = Wscript.arguments.Item(0)
VOL_PROD_KEY = Replace(VOL_PROD_KEY,"-","") \remove hyphens if any

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.RegDelete "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WPAEvents\OOBETimer" 'delete OOBETimer registry value
for each Obj in GetObject("winmgmts:{impersonationLevel=impersonate}").InstancesOf ("win32_WindowsProductActivation")

result = Obj.SetProductKey (VOL_PROD_KEY)

if err <> 0 then
WScript.Echo Err.Description, "0x" & Hex(Err.Number)
Err.Clear
end if

Next

Example

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

  1. Click Start, and then click Run.
  2. In the Open box, type the following command,
    where AB123-123AB-AB123-123AB-AB123 is the new product key that you want to
    use, and then click OK:
