    Hi guys.
    So I had a extra copy of Win 7 ultimate but the trial had run out.
    Now I always get a message when I run virtual/bootcamp saying "Windows 7 build 7601" telling me its not a legitimate copy.

    So, I recently purchased Win7 Pro for a bit cheap price.
    I would like to know if you can downgrade Win 7 through bootcamp?
    I have a disc and not the ISO.

    Sorry, I am not very familiar with Windows as much but I need it for work reasons.

    Thanks in advance.

    There is no way to downgrade the OS, except for deleting the Windows 7 Ultimate partition and installing a fresh copy of Win7 Pro.

    Dang that sucks.
    In Windows, all I need to do is save the data's I need and just move them through external HDD or something?

    I have couple work files and games installed on there.
    In order to transfer them, do I have to reinstall all the files or can I just copy them to the x86 folder (or thats where I save them) and should be all good?

    Many applications have registry entries tied in so just transferring the entire folder might not work. I'd save the savegame files, reinstall the games once W7 Pro is installed then copy the savegame back into the appropriate place once it's all sorted.
