I'm currently running a 32 bit version of Vista, but I will buy Windows 7 as soon as it's available. My question is can I get the 64 bit version? Will all my back up data, such as data files, music and movies still work on the 64 bit version. Or is this just a operating system change and does it affect any other data? I know i'll need new drivers for my software programs, I'm just worried about my back-up data. Please help.
