  1. Activate Windows [Activation key invalid after 20H2 update]


    Hi all,


    I am a Window 10 Education user. I updated my Windows to 20H2 on 12/11/2020. Shortly after the update, I received an error saying that my window is not activated and please activate the window.


    By far this issue has not been causing any major problem to the system, and I heard it is common to have window activation key invalid after a major update. However, it has been getting more of a concern to me as it has already been defective for almost 2weeks, today is 26/11/2020.


    How long more until this is fixed?


    Thank you.

    :)

    activate windows 7 oem key

    There is no difference between the OEM disc and the Retail disc with Windows 7. A retail disc will accept a OEM or Retail key, and vise versa.

    If the OEM Key wasn't going to work with the disc you have, it would have stopped you during the install when it first asked you for the key, not during activation.

    What is likely the problem is that, since the OEM version has already been activated once, it is failing activation again. Activate it over the phone using the option given to you on the failed activation screen, and you shouldn't have a problem activating 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.

    Activate Windows [Activation key invalid after 20H2 update]

    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
