    Windows 8.1 Enterprise Evaluation

    Windows 8.1 Enterprise Evaluation to Windows 8 Final (OEM)


    So for the past week I've been putting together my gaming rig, and I finished the day before yesterday. My copy of Windows 8 was scheduled to arrive two days later (today), and I got hasty and just installed Windows 8.1 Enterprise Evaluation via a USB drive.

    My official copy arrived today, and I'm wondering if there's a way to activate/upgrade (or would it be downgrade since it's 8.0?) without having to reinstall the OS altogether - I've already set up a lot of software that I'd prefer not to redo everything, although I do have a storage drive if a complete reinstall is necessary.

    Any help would be greatly appreciated

    No, not that I am aware of. You can't upgrade from Enterprise to a consumer version. You'll have to reinstall.
