In Windows 10 Task Scheduler, under
Task Scheduler Library > Microsoft > Windows > Windows Defender there is a
Windows Defender Scheduled Scan Task. If you double-click on this Task, it brings up the
Properties dialog, and under the
Actions tab there is a single Action,
Start a program. If you double-click on this Action, you will see that it runs the program
C:\Program Files\Windows Defender\MpCmdRun.exe
with the following arguments:
Scan -ScheduleJob -ScanTrigger 55.
But if you run CMD.exe, and use the
cd command navigate to
C:\Program Files\Windows Defender, and then enter the command
MpCmdRun.exe, there do not appear to be any references to these arguments in the command line.
My understanding was that the Task Scheduler arguments were identical to ones you could use via Command Prompt. If so, is there something I missed looking over the available commands for MpCmdRun.exe in CMD.exe and, in that case, what does the original string of arguments indicate for Windows 10 Defender? Or, if not, is there a universal reference online somewhere for the differences between "command line" arguments vs. their "Task Scheduler" arguments belonging to certain programs?
I ran the task, and it has said
Runnning for a few minutes now, but according to the tray icon for the
Windows Defender Security Center there is no update, and for all I can tell Windows Defender does not appear to be doing anything.
If someone could please enlighten me as to the specifics of this particular command, as well as the details of differences (if any) between Task Scheduler and Command Prompt arguments, I would be much obliged.
