Can I install Windows 7 on a machine with Windows XP using a Windows 7 upgrade CD?

    Question

  • I have a machine running Windows XP.  I want to install Windos 7 on it, but I don't need to upgrade the existing installation.   The instructions on the back of a Windows 7 upgrade disk say that it is meant to upgrade Windows Vista.  It then adds that if the mcahine has Windows XP on it,  I must instead save all user files. programs,  etc., and then do a clean installation of Windows 7.   After that I can restore the files I saved.  (I don't happen to want to do that.)   I interpret this to mean that I can use the upgrade disk to do a fresh installation of Windows 7 on the machine given that there is a preexisting version of Windows, namely Windows XP.   So I don't need a more expensive disk which can do a full installation of Windows 7 on a mcahine which doesn't have any previous version of Windows on it.

    Am I right?

  • Windows XP users have two options:
    1) Start with an In-place upgrade to Windows Vista followed by an In-place upgrade to Windows 7
    The key thing is you need a Vista DVD. So if you have your old Vista DVD, dust it off.

    2) The Offical Microsoft position: Windows XP users must do a Clean/Custom install. That mean backing up all your data.

    Note: You can not use both XP and Windows 7 (via an Upgrade product) to create a dual boot computer.

  • Yes, exactly so.

    A clean install gives the best result, so I'd recommend it over an upgrade-in-place even for Vista owners.

    But my question is whether I can use a Windows 7 upgrade disk to do the clean install?   It presumably will recognize that there is a Windows installation on the disk.  Or do I need a full installation disk which would work whether or not there is a windows installation already on the computer?   I do understand that after a clean install I will have lost everything I had there and would have to reinstall my personal files.

  • As long as XP is still installed and activated you can use the upgrade disc. It will recognize that XP is installed and "Retire" your XP product key so it (XP) can't be used on another computer. Your correct that you need the "Full" product but only if there is no existing / qualify earlier version of Windows (XP or Vista) installed.

    So if XP is already your operating system and you want to move to Windows 7, then the upgrade product will work just fine.

    Start by running the Windows 7 Upgrade Advisor:
    Download and run the Windows 7 Upgrade Advisor to see if your PC is ready for Windows 7.
    It scans your hardware, devices, and installed programs for known compatibility issues,
