    Windows deactivated itself after the last two cumulative updates


    My previously activated windows 10 Pro now says that it cannot connect with the activation server to verify. It still shows the Product ID and Product Key. Also shows error code: 0xC004F074, this system was previously windows 7 Pro and was upgraded to 10 years ago. I have run sfc /scannow and it ran into corrupt files it said it repaired, but troubleshoot tool can still not find a way to reach the activation server.


    Please help.

    :)

    Windows 10 deactivated itself after update

    I have been running Windows 10 for about two months and there had been no problems before. Today, 12/10/15, I updated Windows 10 and it deactivated itself. I didn't deactivate windows. After the update it said windows had not been activated. I can't reactivate
    it and the error code that it comes up with has nothing to do with what happened. Help Please.

    Windows 10 deactivated itself after update

    I bought the windows Pro last year and the code is valid until the recent windows update and now this is showing that my Windows is deactivated.

    Please help. I followed the steps and tried to call the phone number that shows up when you search using the
    SLUI 04 and there seems to be a dead number and the call does not go through.

    This product key was on the back of windows 10 Pro DVD that i bought and shamefully now windows says that this key is not for Windows 10 pro. how is this possible?

    Please suggest steps to get this resolved. other than the ones you already mentioned here.

    Thank you.
