    Windows 10 Pro activation error (0x803fa067)

    Hi,

    I upgraded Windows 10 Home to Windows 10 Pro using VK7JG-NPHTM-C97JM-9MPGT-3V66T generic product key, but when I wanted to active it by the purchased product key ( ends -7MH26) I received the 0x803fa067 error code. How can this be resolved? Any ideas?

    Thanks.

    Gabor

    Cant activate windows 11 pro with windows 10 pro key

    My pc had windows 10 pro running with a digital license i bought 7 years ago and was activated.

    Today i did a clean install of windows 11 pro and when i try to activate i get the error can't activate not a valid digital license 0xC004C003.

    Can I use a windows 10 pro key to active my windows 11 pro version?

    I tried using the generic product key below:
