    Windows 10 Pro Activation Key not working


    Hello,


    I have been having a problem activating my present windows. I recently bought a new computer, and just downloaded Windows 10 home onto it. When asked for an activation key, I entered in the key I have for Windows 10 Pro. I get the following error: The Product Key you entered didn't work. Check the product key and try again, or enter a different one. (0xc004f050)


    Any insight into why this is happening and if there is a way to fix it?

    :)

    Windows 8.1 pro + WMC key activation

    This worked for me last time with a Win 8 key.

    Install Windows 8.1 and enter KMS key during setup. Once in windows change product key to my Windows 8 key. Go to add features and enter my WMC add-on key. Drink a beer to a job well done.

    Windows 8.1 pro + WMC key activation

    So it will be fine installing 8.1 pro with a KMS key, then switch to my 8 pro key and it will activate ok?

    Maybe a daft question but why can't you just install 8.1 pro with the 8 pro key, or is it different keys for 8 and 8.1? seems silly when 8.1 is a free update anyway.

    Installing Windows 10 using Windows 7 key

    Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

    As for getting rid of Windows, delete the Windows folder.
