The scheduled task runs despite its only trigger being disabled

TomK 5

I wanted to test starting a scheduled task manually from PowerShell, so I disabled its trigger which was set to run the task every 15 minutes. To my surprise, the task still ran every 15 minutes despite the disabled trigger. Is this the expected behavior on Windows Server 2019? If so, what is the purpose of the Enable/Disable trigger checkbox? Thank you.

Hello,

What happens if you remove the trigger? Will the scheduled task still execute?

Take a look at the "Conditions" and "Settings" tabs—do any particular configurations within these tabs potentially lead to the task running unexpectedly?

Can the task history offer any insights into how the task behaves?

Regards,

Karlie

Having a similar issue. After OS upgrade from Windows Server 2012 to Windows Server 2019, If my task is enabled and the trigger is disabled, i see the task run anyway on the disabled trigger schedule.

original tasks with schedule were in OS2012 - they rode the upgrade

trying to run these to test upgrade found issue of 'task runs with trigger disabled'

never had this problem in Windows OS 2012

original tasks were built with Windows Server 2008 compatibility setting

tried deleting tasks and re-creating verified no other condition in the task would trigger the running of the task - new task still ran on disabled trigger schedule

deleted trigger - task with no trigger would run on schedule

added new trigger

updated compatibility setting to Windows Server 2019

rebooted, changed schedule to new frequency and start seconds - still starts on disabled trigger schedule

Task History looks like trigger is enabled.

Any help appreciated - i use the trigger disable to 'nicely' shutdown running processes allowing them to complete, but not restart.
