windows xp activation question

I get through hard drives like bread about 3 or 4 in the past six months to a year, under that stance i'm proberly getting a bigger one soon.

The question is, i'm using the same windows pro cd, and i'm activating it via the internet.

so far no problem, but will there be?
i've heard it has a anti-piracy software that only allows activation three times, am i wrong?

The short answer is it can be re-installed and activated on the same PC an unlimited number of times. People do upgrade hardware all the time.

Here is a link to the long version answer.
