I have been reading different threads about activation and all of a sudden it came to my mind that in the past few months I did several hardware changes such as video card, added two hard drives andactivation never was an issue. Also, reading Microsoft's support page I found that to check the activation status of my copy I should go under Programs-> Accesories -> sytem tools -> Activation. That a"activation menu" just is not on my computer. My computer is a build-up and came with XP installed when I bought it. Are there any chances that my XP copy is a pirate version? Does anybody know how I can check my activation status? Thanks!
