Using script
There are 2 scripts below, one for WinXP without SP1 installed, and one for already installed. SP1 WinXP.
The following is a script for WinXP that has SP1 installed (ChangeVLKeySp1.vbs). The usage is the same as the script for WinXP without SP1 installed in the last paragraph of this article (example).
'
' WMI Script - ChangeVLKeySp1.vbs
'
' Windows XP With SP1
'
' This script changes the product key on the computer

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:").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
The following script It is used for WinXP (ChangeVLKey2600.vbs) without SP1 installed.

WshShell.RegDelete "HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\WPAEvents\\OOBETimer" 'delete OOBETimer registry value

result = Obj.SetProductKey (VOL_PROD_KEY)
if err <> 0 then
WScript.Echo Err.Description, "0x" & He x(Err.Number)
Err.Clear

Example: Script Usage
The following example describes the command line How to use a VBS script.
1. Click [Start], then click [Run];
2. Enter C:\\ChangeVLKeySp1.vbs ABCDE-ABCDE-ABCDE-ABCDE-ABCDE-ABCDE
Assume ChangeVLKeySp1.vbs In the C: root directory
ABCDE-ABCDE-ABCDE-ABCDE-ABCDE-ABCDE is the new serial number
The above ChangeVLKeySp1.vbs is applicable to WinXP with SP1 installed, and the use of ChangeVLKey2600.vbs without SP1 installed. The same is true for the method.
3. Then click [OK].
