    No.

    You cannot upgrade in-place from any 32 bit operating system to any 64
    bit one, you must perform a clean install.

  3. As Jane says. No. Whenever you change underlying architecture, you need to
    plan for and perform a "clean" install. There is never an upgrade option.
    You can use the Windows Easy Transfer (WET) in Windows Vista/Windows 7 if
    that is what you're installing, but be sure to use the version on the
    _destination_ DVD, or a 32-bit version that is the exact same release level.
    For a destination of XP x64, coming from 32-bit XP, you'll need to make sure
    you have downloaded the latest version of the Files and Settings Transfer
    Wizard (FSTW) from Microsoft. Otherwise you risk version incompatibilities
    and you might not be able to restore.

    Hi, Karthik.

    As Jane said, it is not possible to "upgrade" from 32-bit to 64-bit (or vice
    versa) at all; a clean install is required. And that implies a reformat of
    the partition, which means all files are wiped out.

    But that does not necessarily mean that ALL files must be backed up. No
    need to back up Windows itself, of course, because all those files will be
    recreated by Setup. And backing up your program files might be useless
    because you'll need to reinstall those from original media after your 64-bit
    Windows is installed. Even if your 32-bit program will run fine on 64-bit
    Windows (and almost all of them will), you will need to install it again so
    that its setup program can make the required entries in the new Windows'
    Registry. (Some simple applications, of course, don't need to be
    "installed" but can be run just by clicking their executable; these are
    exceptions.)

    But, yes, definitely back up your data files! These can be restored and
    used by your re-installed programs in 64-bit Windows. Or, if you have safe
    space on a separate HDD or a separate partition, copy them there before the
    clean install, then point your reinstalled application to that new location
    afterwards.

    You have more than one option.

    If your user files (word processor documents, pictures, videos, email store,
    &c) are now in or are copied or moved to a separate directory than your
    system, it is possible to use an install method that leaves them all intact.
    You can simply install the 64 bit system to a separate partition, install
    your applications to that or a different, separate partition.You can then
    remove the old system and application directories and reclaim the space by
    enlarging the new partition(s) as appropriate.

    You can shrink the present partition(s), install the 64 bit system to a
    separate partition. You would then install your applications. Windows 64 bit
    will automatically install a boot manager you would then see when the system
    starts and use to select the system for use.

    Alternately, you can install 'Virtual Machine" software and install the 64
    bit system on that. e.g. VMWare. You will have to install your applications.
    It is usually possible to arrange to share the user files between the
    original OS and the OS within the VM.

    You will need valid licenses for the OS and all applications for each
    installed copy. Check the appropriate license provisions for each
    application. Some might provide for more than one install. E.g. Microsoft
    Office Home and Student 2007 allows three.

    That said, it is wise to make sure you have the install files for your
    applications and back-ups of your user files, and sources for all needed 64
    bit device drivers for your hardware. The Windows DVD might have many, most
    or all of them but might not.

    Remember, while it might be easier to seek forgiveness than ask permission
    as one saying would have it, it is rarely easier to recover afterward than
    to plan thoroughly.

    Good luck.

    Lets be clear about this:

    You should back up everything you want to keep on a regular basis *anyway*
    but **in particular** you should make sure you backup before upgrading your
    operating system. 32bit or 64bit doesn't have anything to do with it.
