Hi. The friend of mine is want to buy AMD 64 processor based system. He has Windows XP Pro (regular, 32 bit) from his old comp. So, can he install his old windows for 64 bit processor, and if so, would it be just wasting the 64 extension of his new processor, or it still can be usefull.
And another question, is the build 1433 the most recent version of windows XP 64 bit edition Pro, if not, which one is the newest?
