    Hi there

    I also asked about this in another thread -- Note though if you check the PRODUCT ID (NOT the KEY) it will be different from your original OS one. The Ms severs take some sort of Hardware mapping of your computer too - but as a lot of hardware around the world will be IDENTICAL Ms must have some way of UNIQUELY identifying each machine -- maybe the product ID is part of it.

    I'm not sure that Ms can get the part number of every significant piece of hardware in your system - often it's not available.

    Also what triggers re-activation is quite a mystery anyway. I've swapped a CPU and a MOBO and was never asked to re-activate - but changing to bigger HDD's or adding a Blu Ray device caused me to re-activate -- "Go Figure...".
