I have a AMD Athlon 64 X2 Dual core processor on my computer with Vista Home Premium, but I believe it using a 32 bit Vista version(how can I find out what bit my system is really using?). Can I upgrade to Win 7 64 bit Home, if my present OS is using a 32 bit Vista OS. | |||||

You cannot upgrade a 32-bit OS to a 64-bit version; you have to do a clean install. Don't worry, though, all your old files will be moved to a new directory called To find out which version you have, go to Control Panel -> System and Maintenance -> System, and it should say either 32-bit or 64-bit Operating System. | |||
