Stop automatic reboots w/updates + auto-install Defender definitions

    Guys, I think I got it. It's been working for a few days now (so I'm keeping my fingers crossed.)

    The problem might have been in the Task Scheduler (or my inability to fully grasp its convoluted interface) and not in the command line I was using.

    So here are the steps that worked for me:

    1. Set up GPOs (need Windows 10 Pro): run gpedit.msc as administrator, then go to Local Computer Policy -> Computer Configuration -> Admin Templates -> Windows Components -> Windows Update and set the following:

    - "Configure automatic updates" set to enabled, pick option "3 - Auto download and notify for install"
    - "No auto-restart with logged on users for scheduled automatic updates installations" set to enabled.

    Then reboot.

    2. I found this free tool that will do the scheduling part. (Note that the tool is designed to wake your computer from sleep. Since in my case it's a desktop and it is always on the waking part was not an issue. But if you do it for a laptop I would set the interval for longer than an hour, say to 4 hrs or so that your laptop doesn't wake up every hour in the bag.)

    I then set up the schedule as such with the following command line arguments from a cmd window:

    path-to\wosb.exe /run /systray tm="+10:00" file="path-to\cmdNoWnd.exe" params="\"%ProgramFiles%\Windows Defender\MpCmdRun.exe\" -SignatureUpdate" repeat="1:00:00"

    What it does it runs my update Defender command (
    MpCmdRun.exe -SignatureUpdate part) without a window (cmdNoWnd.exe part) 10 minutes after I run the line above and then repeats it every hour (repeat="1:00:00" part.)

    3. And since I was at it, the line above calls another free tool (
    cmdNoWnd) from the same site that runs my Defender command without showing the command window. Very handy and no need to do the VB script hack as was suggested above.

    Is it necessary to wake it up to perform definition updates, which don't seem urgent?

    I prefer the above, which entails no installation, to the following, which needs to be installed.

    I don't think there's any installation needed. It's just a file you can run.

    But otherwise, yes of course. I'm sure there's more than one way to do it.

    Do you mean it is a portable program?
