    Hello there,
    What would be the advantages/disadvantages of running an operating
    system XP or Windows 7 on 64 bits, can I still run all my 32 bits
    programs?
    Thank you

    The advantage of running a 64-bit version of Windows mostly exists
    only if you also run 64-bit applications under it. Bear in mind that
    there are very few such applications available yet. If you are
    presently running 32-bit Windows, you don't have any 64-bit
    applications, so to achieve any significant advantage, you not only
    have to replace Windows, but also your applications, *if* (and that's
    a big "if") 64-bit versions exist.

    Also note that you will need 64-bit drivers for all your hardware.
    Those drivers may not all be available, especially if some of your
    hardware is a few years old. So it's possible that you might also have
    to replace things like your printer, scanner, etc.

    So the answer to your question is that it may not be a great idea
    right now. That will undoubtedly change in the near future, as 64-bit
    applications become more available, but for now, 64-bit Windows often
    means some extra trouble and expense for little or no benefit.

    On the other hand, installing 64-bit Windows instead of 32-bit Windows
    makes you able to buy 64-bit software as it becomes available, instead
    of the older 32-bit versions. That means that installing 64-bit
    Windows--even though it may do very little for you at present--puts
    you into a better position for the future.

    One additional point: the 64-bit version lets you use more than the
    approximately 3.1GB of RAM that the 32-bit version can use. Very few
    people need or can make effective use of more than 3.1GB, but if you
    are one of those who can, that's something else to consider.

    Probably, but there may be an occasional one that won't run under
    64-bit Windows.

    Almost all should work... with only a few exceptions.

    Frequently it is the peripheral hardware where the software/drivers are
    lacking.

    For comments on WinXP x64 operating system, read the
    customer reviews here. By reading this, you may avoid
    making a mistake. (This is separate from the initial
    question.)

    Later 64 bit OSes, may have better end user reviews.

    If you look around, you may be able to find an "Upgrade Advisor", or
    compatibility information, to help you in your decision.

    The "Upgrade Advisor" has these prerequisites.

    * Supported Operating Systems: Windows 7; Windows Vista; Windows XP Service Pack 2
    * .NET Framework 2.0 or higher if running Windows XP
