Modify a scheduled task without running it

It seems that when I use PowerShell's Set-ScheduledTask command (or the SchTasks command line utility) that the task runs immediately after being modified.

Is there a way to modify the task and NOT have it run immediately, but only run at its next scheduled time?

Thanks.  Greg.

Sounds as though the task when created has the trigger set to run on creation or on modification.
Make sure to change the -trigger when editing to make sure it is not on create/modify.

The default behaviour is not to run on creation or modification, so I agree to arnold.

Thank you both.  I was unable to determine where, using the new-scheduledtasktrigger or the set-scheduledtask commands, I could set the trigger as Arnond suggested.  However, I did discover that if I modify an existing task that is set to run periodically, that if the start date and time are in the past that the task will trigger because it sees that the interval has passed.  If I use new-scheduledtasktrigger to set the start date and time in the future, it does not run upon being changed.

If you can show me a command that can modify the trigger as you suggest, I will investigate that as well.

Thanks for you help!

The behaviour you described may result from the setting of
 (get-scheduledtask test).Settings.StartWhenAvailable

Open in new window

being True for the task. You can change that e.g. with
get-scheduledtask test | % { $_.Settings.StartWhenAvailable = $true; $_ } | Set-ScheduledTask

Open in new window
