    Windows 10 Anniversary Update Issues

    Problems with W10 Anniv auto update:

    Mom's: (x58 Xeon 5677) Windows Defender was not turned back on automatically (it was "on" in the 1511 edition) and she had a Trojan. Full system scan to eradicate.
    Her Epson printer was knocked off, had to uninstall by Device Manager pull USB cable and reconnect cable. W10 did the rest.

    Step-mom's: (HP pre built) Windows Defender not turned back on by default. Her USB Seagate Expansion Drive 2Tb was offline so all backup routines were halted. Had to rerun backup plan. Had her do a full virus scan.

    Step-dad's: (Dell Optiplex tweaked upgrades) Windows Defender not turned back on by default. Full Scan.

    Task to auto update windows defender definitions disappears

    My mom has a new laptop with windows 8.1, we always set the windows updates to manual.
    On our other windows 8.1 computers I have created a task for auto updating windows defender definitions, which works fine for us.

    This is how I created this task:

    "Click on "Create Task", name it what you like (mine is Daily Signature Update), set the trigger as the time you want it to run every day.

    For Action browse to Program Files\Windows Defender\MpCmdRun.exe and select it. In "Add arguments" add -SignatureUpdate -MMPC"

    But somehow this task disappears once it has run on my mom's laptop.
    I'm logged in as admin and then I also tried it with running the task scheduler as admin, the task just disappears every day for some reason, while it works fine on our other windows 8.1 computers.

    Anyone an idea why this task disappears every time?

    Thanks.

    Turn off auto updates for Windows Defender

    Windows Update is conflicting with Windows Defender's auto-update...


    Stargate,

    1. Every Windows defender definitions update is called KB2267602.
    2. Windows defender uses Windows update to do its updates automatically.
    3. As you already know, Windows defender also allows you to update through the Windows defender UI.

    Whatever the cause of your current problem, it is not a clash between Windows & Windows defender running updates independently [there is no such thing as Defender's built-in auto-update].
