Windows 10: Windows Defender no longer auto updating since last Windows update

I noticed that Windows Defender has stopped delivering auto updates.This started either after the Oct big Windows update.I tried some hints found at online forums, but it guess these where all older posts that no longer apply for the current issue, none of them fixed the problem.I use Windows 8.1 64bitUpdates are set to first alert me but let me install at my time we do not have very good internet speeds or stability here for such huge updates to get done in the background.What is the issue and how can it be corrected other than check manually in the Defender program itself??

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.

 

Why won't Windows Defender not auto update anymore

I have have windows updates set to notify updates , I will install myself, because I want to make a system restore point before installing updates.

Because of this windows defender does not update automatically and I had to create a task for updating in the task scheduler, which I did but it does not work anymore since I re-installed windows.
What am I doing wrong?

 

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:
