Task Scheduler repeat task not triggering

Just in case you trigger the task manually...

I have just come across this same problem on Window 7. I haven't tested it with any other version of Windows.

It seems that repeated tasks are not executed when run manually (right click on a task and then select "Run").

When run manually, the task will run only once and that's it!

This is a trip wire since it's natural that people simply run the task manually right after its creation to check whether it's working as expected.

What you could do, set the trigger to "At startup". After you rebooted the machine, the task should then be in the "Queued" status. This means it will run at the configured interval.

I ran into this problem me too, I was able to solve it by setting the start date and time one or two minutes ahead of the time of making the task to trigger the action and start repeating it as configured.

The correct way to set this up is to set the start time any time in the past, then select "Run task as soon as possible after a scheduled start is missed" in the Settings tab.

Manual triggering is for testing. You need a real trigger to start repetition.

I solved this by setting up a trigger for system start, as suggested, but if that session fails or you make edits, and you don't want to restart the machine, just set an additional trigger to perform the same sort of repetition on a daily basis, with a start time in a minute or two.

You can then leave both triggers running, and set them both to not start another instance if one is already running, with appropriate timeouts to kill the current instance if it runs too long. This way, you are assured of triggering, even if the instance that started when the computer was last rebooted dies.
