    Can someone please tell me more about this situation? This Windows Defender update is repeatedly failing to install: KB4052623 (Version 4.18.1905.4) installation fail with Error 0x80070643. I have searched various forums for a solution, but have found none so far.


    When I try to update Windows Defender from within Windows Defender, I get another error message saying: error code -2147023293 protection definition update failed.


    Thanks in advance for any help provided. Here are the respective screenshots of the error messages:

    Oh, and I should add that there are no other 3rd party antivirus/antimalware programs installed on this computer.

    :)

    - someone who resolved this although non-trivial.

    KB4052623 is repeated at intervals, so you could just ignore it I suppose. Hiding it might not be a great idea.
