    I will be upgrading my motherboard i have some ??


    So i will be updating my motherboard hopefully in a few days, i know i can take steps to were i will not have to re do my operating system which is win 8.1, as i have seen people do it. But my question if it works like i want it to and all goes well, how would i reactivate win 8.1 if it ask me to as mine was the update from MS that was free at the time, and thus i did not get a product key for it at all it just installed, will i be able to use my win 8 pro product key to reactivate?. I have seen people do the motherboard with out re-installing win 8 and all goes very well.

    Hello Tony,

    If this is an OEM Windows 8 key, then you are out of luck since it is permanently tied to the original motherboard.

    If this is a retail Windows 8 key, then you could use the ISO file from Option One in the tutorial below to create an installation USB to install Windows 8.1 and activate with your Windows 8 key.

    Maybe it's the fickle finger of fate, being kind to an old man, but......

    Here's my story:
    I hava a little 2.5", 160GB hard drive that I had set up on my Desktop PC, which uses an AMD Athlon X2,5200+, 64 bit CPU chip. After doing the full install of Windows 8.1, 32 bit, and setup on the desktop, I pulled the little drive and shelved it for future use.

    Skip forward to last week.

    I was given an HP laptop PC, with a blown Hitachi hard drive.
    Not being able to recover the drive, to use it again, I basically trashed it.

    Then I took the little drive with Windows 8.1 on it and installed it in the HP Laptop.
    Marvel of Marvels...... it booted right up and after installing a few hardware drivers it was on-line and running like a champ. Activation did not change.

    The Clinker:
    Both computers are using an AMD Athlon cpu. Windows 8.1 evidently thought it was still on my desktop PC, but with some different video, LAN and sound cards. It automatically installed compatible drivers for all the hardware. I had considered just trashing the little laptop, but now it's running so good...... I think I'll keep it.

    I've actually seen this phenomenon before, where a Hard Drive moved from one AMD PC worked perfectly on a different PC with an AMD cpu, after installing some new drivers.

    I don't know if this works on PC's with Intel cpu's. I try not to use PC's with Intel cpu's.

    So, as long as you're going from one motherboard, with one brand of cpu, to another motherboard with the same brand of cpu, you might not have to reinstall or even re-activate.

    Good luck with that!

    It was windows 8 i bought and purchased at the time that they were like 79 bucks or something like that. but if i install the new motherboard without re-installing anything and it boots and just ask me to activate can i use the win 8 pro key for win 8.1?

    Most likely, it'll only accept a 8.1 key.

    The 8 Pro key will only work to activate a current 8 Pro installation.

    You don't, but you could download the ISO file from Option One in the tutorial I posted above that will allow you to do a clean install of 8.1 Pro and be able to activate with an 8 Pro key.

    Unfortunately, not with a 8 Pro key on a 8.1 Pro installation.
