How can I change my Windows XP CD-ROM key?

A. To change your XP CD-ROM key, perform the following steps:

You can also use the following script that Microsoft provides to change the CD-ROM key:

  '   ' Windows Management Instrumentation (WMI) Script - ChangeVLKey.vbs  '  ' This script changes the product key on the computer. Service Pack 1  ' must be installed.  '  '********************************************************************  ON ERROR RESUME NEXT  if Wscript.arguments.count<1 then  Wscript.echo "Script can't run without VolumeProductKey argument"  Wscript.echo "Correct usage: Cscript ChangeVLKey.vbs ABCDE-FGHIJ-  KLMNO-PRSTU-WYQZX"  Wscript.quit  end if  Dim VOL_PROD_KEY  VOL_PROD_KEY = Wscript.arguments.Item(0)  VOL_PROD_KEY = Replace(VOL_PROD_KEY,"-","") 'remove hyphens if any  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

To use this script, go to the command prompt and run

changevlkey.vbs 

where is the name of the new key that you want to activate (e.g., ab123-ab123-ab123-ab123-ab123).
