Or you could always go recycle dumpster diving of thrown away XP Pro machines with the coa stickers still on them, never know what treasures you may find to cannibalize!..

That key is a old volume license corp key, you can add it to your sif file so Windows won't nag you for a key but your version won't be genuine.

Yes will be, if you know how

Sure you can force a activation with it but still won't be legally genuine with the Microsoft Genuine Advantage Tool for XP.
