what is the best way to upgrade from windows pro 32 bit to a 64 bit OS so i can fully utilize my 4 GB of RAM? right now my computer is only using 3GB. i am looking at several options:
1) install windows xp pro 64 bit,
2) intall windows vista and then upgrade to windows 7 64 bit (ultimate or pro)
3) install windows 7 32 bit, which would defeat my original purpose
in all case, i might need to reintall my applications.
can someone help me? thanks.
