I try to upgrade/install Win Pro 64 from 32 bit to max the memory on my PC Dell XPS 410 and every time I get the blue screen. I try l loading Win 7 pro 64 everything went well memory maxed to 4 G but it looks lie I need to upgrade all other hardware in order to work. Looks like another Vista to me. It looks good and nice and it looks more like an apple window that you have all applications running and able to sweetch faster and easy but it does not help me any thoughts on how to install win xp 64?
