Hi I am about to upgrade my CPU to an i5 4670k but to do that I need to change my motherboard. I heard that you need to re-install windows 7 if you change your motherboard since I want to continue to use the same harddrive. My problem is that I want to purchase a SSD and then install my windows there and also use my Harddrive at the same time. On my previous computer when I tried to install Windows vista on 2 different harddrives i got a windows genuine, is there any way to prevent this?
