For 2 weeks I've had Vista on C drive and Windows 7(x86) on D drive. I've just formatted D and installed Windows 7(x64) and now, whether I boot with Vista or Windows 7, the OS I'm actually using is shown as being on C drive. So, when I boot Windows 7, all the files relating to Vista - plus all the other files which I stored on C - are magically transferred to the D drive. When I boot with Vista, all is back to normal.
It seems strange that this happens only with the 64 bit Windows 7. The 32 bit version was installed on D and stayed there! Can someone explain this phenomenon?
Also, should I concern myself with the 2 'Program Files' folders, one of which has '(x86)' after it? Am I right in thinking that if a program is 32 bit (but still usable with a 64 bit OS) Windows 7 will direct it to the correct Program File folder meaning I don't need to 'browse' to the other one if given a choice when installing?
