    Valid Win 10 Pro suddenly shows "Activate windows" watermark. Error code: 0xC004C003


    So a few weeks ago I got this "Activate Windows" watermark in the bottom right on my Windows 10 Pro Error Code: 0xC004C003.


    A friend got a similiar issue a week prior to me but he said it stopped appearing as random as it started, so I waited...


    Now here I am, still with the damn watermark..


    I've updated windows.

    I've tried troubleshooting with no success.


    I don't know what to do anymore.


    Edit: Fortnite microlags when this watermark is visible. I know the watermark is the issue here because sometimes when I boot the computer the mark isnt there and Fornite is playable, but after a while the mark appears and the microlag starts.

    Error code: 0xC004C003

    My Windows 10 Pro Upgraded from Win 7 Ultimate had been Activated but after I Replaced the Mother Board, it Shows that "Windows Is not Activated".

    It would be so kind of you, if any one can give me an effective solution for the Problem.

    It also shows Error code: 0xC004C003
