Windows 10: Task bar time does not update? and other things disappearing

I managed a screenshot, had to use windows key +s + shift to snap a picture showing how often overnight the time and date just quits updating the main screen, but click on time and it shows the correct time. Snip and sketch could not function as the PC was too slow when this happens.

When it does that all the quick bar icons disappear too. And the PC runs really slow when that is happening. Like it is talking 20 times longer to do anything related to file management. Internet web browser speed is not affected. I have 16gb memory and several TB sized drives and a 6 core AMD CPU on this particular PC.

I notice this problem often in the AM, eventually with use during the day, the problem goes away. Win 10 is up to date
How can I fix this?

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.
