    Is it me or are the disk usages significantly different (a few GB)
    between a 32-bit and a 64-bit installation? This is on the same machine
    (ASUS K8V SE Deluxe with an Athlon 64 3200+ 754 CPU), same Ultimate
    Edition, and similiar options in installation. I did notice an extra
    Program Files (x86) in my C:\ root directory that takes over 300 MB. Is
    this the only difference that makes the disk usage different?

    Thank you in advance.

  2. I doubt that the Programs Files (x86) accounts for the difference. There is
    a different amount of system code and that is probably the difference. The
    PF(x86) is where 32bit software is installed. Native 64bit apps go in the
    Program Files folder.

    Phillip, yes, there is a difference of approximately 3GB between a fresh
    install of x64 and x86. My x86 install was @8GB, x64 @11GB.
