Hello. Few years ago I bought Windows Vista Home Basic x32 ONLY. Now I need OS processing on x64 CPU architecture. Can I somehow, using Windows Anytime Upgrade, upgrade my old OS to new x64? Maybe I can firstly upgrade it to Win Vista Home Premium x32 and then to x64? Also, I wanted to ask you if you really can feel the difference in functionality using x64 OS (ofcourse, on x64 CPU) instead of x32 (on the same x64 CPU). Thank you in advance and sorry for my poor language (I am not english native speaker).
