    Yep, they all look fine to me as well.

    I was just explaining why you would have seen that the task may run at a different time that what you had scheduled. If the task fails or is unable to run at the scheduled time, the checked "Run task as soon as possible after a scheduled start is missed" option will have the task run later when able. That's all.

    I'm not sure what is stopping or preventing the task from running at the exact time you scheduled it to run. Do you have anything else running or scheduled to run at that time that may be causing it to be stopped?

    As a test, you might change the time to when you will be on the computer to monitor it's activities to see if something stands out.

    Hey Tony,

    By default, the "Run task as soon as possible after a scheduled start is missed" option will have the task run later when it's able to. It's nothing to worry about it.

    so i looked at the task scheduler there is nothing else starting at that time in there 3 am is very strange i have my stuff set to run on a sunday at 3 am. and whatever is triggering this windows defender to start every day of the week at various times and terminating itself is very strange. and what is wired i can trigger my task from the Maintenance section in action center. so what i think is happening and again this is pure speculation is that the action center Maintenance schedule is trying to run this thing every day, and it starts then terminates it?

    Read if you like i was posting when you were but you just confirmed my suspicions lol.

    Yeah, the automatic maintenance will perform a WD scan as well.

    i just started it from maintenance center to see if it terminates itself.

    If the computer has a lot of activity during automatic maintenance, it may be terminated until later or next schedule when there's not so much activity.

    Yeah, unfortunately with an OS upgrade/update, it resets system features.

    If you like, you should be able to export the Windows Defender Scheduled Scan task as a backup to be able to import (restore) as needed in the future.
