    Unable to update Windows Defender in Windows 8.1


    Hello,

    I am unable to open Windows Defender.

    Also I am unable to install the latest update to Windows Defender through Windows Update KB2267602 Version 1.325.745.0.

    I tried downloading through Microsoft website and installing manually but it does not work either.

    Please help.

    :)

    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:

    Windows 8 failure configuring updates and reverting

    I agree 8 is awful! It's not for me though... I replaced a broken screen in a Win 8 laptop that was given to me and I am going to give it for free to someone that can't afford one so they can do homework at home. Yes I took it from 8 to 8.1 back on 10/09/2014. This is what I posted there...

    "Great post! I found a similar one. I would like to point out that you may want to edit your OP...

    1. Step 1 should read to disable AUTOMATIC updates, not disable manual updates.

    2. KB2871398 should really read KB2871389

    I would like to say that KB2917499 may also be needed as it was in my case. I also had to run the Windows Update Troubleshooter after installing those 2 updates. After these steps I was able to begin my 8.1 download from the Microsoft store. I don't know if it made a difference or not, but I also went into the Bios and disabled "Secure Boot."

    It was a helpful post. Thanks!
