Activating on New Machine

[Earl Partridge]

I recently activated Windows XP Pro on a new machine. Since I had
previously installed this XP on another machine I was expecting a challenge
that it had previously been activated on that other machine. There was
no challenge, the activation was accepted. Why?

Earl;
Most likely because enough time had passed.
