How to Change from Windows 7 Ultimate to Windows 7 Professional RRS feed

  • General discussion

  • Machine came installed with Vista and upgraded to Windows 7 Ultimate 15 months ago using Action Pack licensed software. 

    Decided not to renew Action Pack subscription, so have bought a genuine copy of Windows 7 pro.

    What is the easiest way to change the operating system?

    Do I have to de-install and re-install?

    Or can I just change the product key - if so how?
