    Windows update and windows defender issues

    We suggest you to avoid installing any cleaner or anti-virus software that may interrupt the function of Windows Defender. Make sure that Windows Defender is always on. To do this follow these steps:

    • On the Start menu, type Windows Defender and hit enter.
    • Click Settings.
    • Turn Real-time protection on.
    We also recommend you to install the latest update for Windows Defender.

    Should you have further questions, feel free to get back to us.

    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:
    Let your Windows 8 Defender update itself automatically.

    Windows Defender update

    Defender updates no longer shown

    Sorry but I just want to see Defender updates listed in my update history. Updates for office 2010 etc are shown so why not Windows Defender?
