    Windows 10 Problems getting 'Definition Updates' for MS Defender MS Defender updates not...


    Since I have gone to Windows 10 v2004 June 2020 I have had problems with Microsoft Updates to my machine. I seem to get the Cumulative Updates once or twice a month, but go weeks without any 'Definition Updates' which are mostly updates to MS Defender. I have MalwareBytes 4.2.1 Installed. I have had both MS Defender and MalwareBytes running together for several years w/o any problems with Windows Updates. Real-time Protection for MS Defender is OFF, as this is done through MalwareBytes. When I go into Windows Security > Settings > About, it shows:

    AntiMalware Client Version 4.18.2008.9

    Engine Version 0.0.0.0

    Antivirus Version 0.0.0.0

    Antispyware Version 0.0.0.0

    The status of Windows Security Center has 'no actions needed', but I am not sure why the Engine, Antivirus, and Antispyware Versions are all 0.0.0.0.


    In Windows 10 v1909 under Settings>Updates&Security, I had an option to 'Install Updates Automatically' which I always had on as suggested. I no longer see this setting.


    I have talked with numerous Support Persons by phone and am unable to resolve this problem.


    Thanks,

    defender definition updates fail


    Something is not right here. I use Norton 360 on 3 pcs, and Defender is switched off, and I do not get any Defender updates.

    defender definition updates fail


    Hi Brink. I got a link to this forum from a thread I created on the Microsoft answers site. Not sure if this fix will address the issue of Defender definition updates failing to install and generating an error message whenever Windows Update downloads the latest defs. Here is an example of the message:


    "Definition Update for Windows Defender - KB2267602 (Definition 1.213.2537.0) - Error 0x80070643"


    I have contacted MS 3 times and others have done the same or suggested fixes that they thought might work to no avail. The problem boils down to MS policy in Win 10 to download all updates whether you want them or not. Since I am using Norton Internet Security Defender is turned off but MS insists on downloading the updates and the design is so poor that the updates fail if Defender is off. I have suggested 3 options to MS but all they do is hide the failed update temporarily only to have the next one fail again. As a former programmer it seems to me there are 3 options to stop these error messages:

    1- don't try and install definition updates when Defender is off.2- allow the files to be installed even if Defender is off. This would not only not hurt anything but would keep the definitions current so if I ever do decide to switch to Defender I will have the most current definitions available. (seems like the best option to me)
    3-if Defender is off just squelch the error message as it is NOT REALLY AN ERROR IT IS DESIGNED TO DO THAT?

    My question to you is I don't have a problem with Defender being on or off I have a problem that since it is off I get error messages whenever Update runs. Is this going to stop the error messages or will it just ensure that Defender is off and because of the piss poor design of Update continue to have the definition files fail to install and error messages to be generated? Thanks.

    SEtting up automatic updates for windows defender on windows 8

    I have found this on the internet en have set up a task for automatic definitions update for Windows Defender but a window pops up when this starts to run.
    Is there a way to set this without any window popping up so that it just runs in the background?

    Now I'm using
    "C:\Program Files\Windows Defender\MpCmdRun.exe" -SignatureUpdate -MMPC

    I'm currrently using it as described here:
