    Cannot activate Windows 10 Pro Key


    Hi,


    So I am in a bit of a complex situation as it pertains to my Windows 10 situation, and I could really use some help sorting through this.


    When I first reinstalled Windows on this computer, I chose Windows 10 Pro instead of regular Windows 10- I am aware that to rectify this would usually warrant a reinstall.


    However, instead, I just bought a Windows 10 Pro Key from a third-party. I have the key, however when trying to use the "Change Product Key" option, I am given the error "We can't activate windows on this device right now. You can try activating again later or go to the Store to buy genuine Windows. 0x800705b4.


    I have tried troubleshooting, and using command prompt to force the activation. Any help is greatly appreciated.

    :)

    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.

    Cannot activate Windows 10 Pro Key

    Windows 8.1 pro + WMC key activation

    I was considering buying a WMC pro add on for my windows 8.1 pro install, but have googled and found some people had trouble activating it. Has anyone on here got any experience with this.

    As to my install, I have a real Windows 8 pro key. So I installed windows 8 pro using a MSDN retail .iso which was activated soon as it finished installing , then I updated to .1 pro.

    When you buy the WMC add on, it changes your key, I have read some people have had trouble activating it, now mine activates from windows, I hate doing the phone activation crap, so I don't want to have to do that after the WMC add on finishes installing.

    The question is, what happens to my windows 8 pro key, is it still usable? and how would i go about if I had to reinstall? would it have to be-

    Install win 8 pro-update to 8.1-install WMC add on, or could i use a windows 8.1 pro with WMC disc?

    Thanks guys
