  • Windows is not designed to be moved from one motherboard to another. Sometimes you can simply change motherboards and start the computer, but others you have to reinstall Windows when you replace the motherboard (unless you buy the exact same model motherboard). You will also need to reactivate after the reinstall.



    Retail copies can be moved, OEM copies can not be moved to a different computer.


    Can You Move Windows 7 To A New Computer

    If it's a retail Full or Upgrade license - yes. You can move it to a different computer as long as it's only installed on one computer at a time (and if it's a Windows 7 Upgrade version the new computer must have it's own qualifying XP/Vista license). The previous Windows 7 installation on the old computer must be formatted/deleted. You might have to call Microsoft and explain what happened to complete the activation. Activating it on the second computer will automatically in effect "deactivate" the license for the first computer. The key will work with both 32 and 64 bit, but only one can be installed at a time.

    If it's an OEM license - no. OEM licenses, including Windows preinstalled on a computer before purchase and Windows bought separately, are tied to the first computer they are installed on and can not be transferred to a different computer. To install Windows on a different computer you will need to buy another copy.

    Activate Windows 7 on this computer

    If online activation fails:

    Call Microsoft Using Manual Phone Activation

    If you have trouble activating Windows 7 you can call Microsoft to activate by doing the following:
    1. With Windows running click Start, then in the Search box type:  slui.exe 4
    2. Press Enter on your Keyboard
    3. Select your Country.
    4. Select the Phone Activation option, then call the number given and hold for a real person.

    For more details:

    Note: If it’s an Upgrade - if you are still installing Windows and at the Enter Your Product Key page, do not enter your key and uncheck "Automatically Activate When Online" then click OK/Next to finish the installation.
