Now the issue i am facing is that i can't create this task or when a users Login (At Log on of any user)its clearly mentioned for LogOn i need to be an admin to create the task.

But there is nothing mentioned like that for boot trigger.

can someone plese guide why only time trigger works fine but for boot trigger or login trigger i need to be an admin as i gt error General access denied

Though i can esily create a task both for login and boot from task scheduler without running it as an administrator

but for it to create it in visual studio i need to run it as an admin otherwise it gives general access denied error
