    Update Installation Problem (Update: KB2267602 (Definition 1.291.278.0)) (Error 0x80070643)


    "There were problems installing some updates, but we'll try again later.



    Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.291.278.0) - Error 0x80070643"


    I am trying to install this update for a lot of time

    Tried many things in order to fix the problem but still the same error again and again


    I used the Windows Troubleshoot tool from Settings> Update and Security> Troubleshoot> Windows update

    It didn't even detected the problem


    Tried to use the Command Prompt to sort of reset the "windows update downloading zone"

    by:

    1) Stopping four things(Background Processes)

    2) Renaming two folders

    3) Starting those four things again

    4) Restarting the PC


    Please help!

    I will be very thankful to you

    :)

    Thank you for your reply.

    I have done everything as suggested and I have run the Update Troubleshooter and the reply is still:

    "Service registration is missing or corrupt."

    I have also treid to install the update again and got the same message as before i.e.
