Повторной активации не потребуется.
Я просто приведу высказывание человека, который вполне разбирается в том, что говорит.

At the moment of activation XP supposedly locks itself to the machine it's running on using 10 "id's" from various hardware components. I suppose you can find the list but some of them are: MAC address of the NIC, processor serial number, etc. There's an algorithm that lets up to three of these IDs -- for example, changing the NIC -- but changing the fourth causes XP not to start. Every three months the machine is relocked to the current config so if you change three things in in month two, you have to wait until month four before you can change any other parts -- and then you can change only three more, etc. At least that's the way it was reported to work when it came out.

Если какой-то момент непонятен, то переведу. Вкратце, не надо менять более трех компонентов в течении трех месяцев.
