I am building a new computer and do not wish to purchase XP Pro again. I want to remove XP from current system and move it to the new one, and revert back to Win 98 for the current system. As I understand it, Microsoft keeps track of my components as registered and will not allow me to use XP on two computers unless I purchase a 2nd copy. Would it make more sense to purchase an OEM version of XP? In any case, my Pro version needs to be on the new system, so is there a procedure to move XP over to new hardware? Thank you.
