    This key cannot be used to activate this edition


    Hey guys, I'm trying to activate windows but I get the error "This key cannot be used to activate this edition of windows."

    I am on Windows 8.1 Pro WMC and I bought a legit key. I was previously using a KMS activator, which I have uninstalled and have removed the previously installed keys.

    Could you please help me out?

    I just had the Win 8.1 Pro key. Don't need WMC since its being phased out in Win 10 anyway.
    SO, had to download the Win 8.1 Pro ISO and update windows with the new product key while choosing the option to keep my previous files and settings. Might be helpful for people having issues with activation.
