I've windows 7 professional installed in my laptop...If I want to upgrade/install to windows home premium or ultimate then will my win 7 professional product key work??? OR Is my win 7 professional product key just for win 7 professional??? Is it the same case if I want to upgrade or install win 8 (after formatting the hd which removes win 7) & my win 7 professional product key doesn't wok???
I really need to understand this....thnx in advance
