Thanks for the tips DOC.
I´ll take a look at thos links .

I am not after something illegal, just wanna cross the information in the stickers with the ones already registered cause there have been some problems while activating XP´s in an untidy way, FE not sticking the number to the PC.

BTW jlo?
I was wondering if your KixBin can read and translate this value?
Code:
  
$ToKixBin=ReadValue("HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\", "DigitalProductId")


Its something like this:
