问题:

I am a bit confused on how to schedule a task to run on system startup as SYSTEM with schtasks command line and I have read MS's documentation on schtasks.exe. Can someone here help me.

回答1:

The following command schedules the MyApp program to run every time the system starts, beginning on March 15, 2001: the date is optional.

{ schtasks /create /tn "My App" /tr c:\apps\myapp.exe /sc onstart /sd 03/15/2001 }

回答2:

Using /RU SYSTEM makes a task run as the system.

回答3:

You can specify account to use for both at task level as well as at command level.

/U to specify user account that should be used to run the actual command /RU to specify user account that should be used to execute the scheduled task

By default both would use "System" account i.e. with the permissions of the user logged in.
