Service Runner
Because Automatic School Bell uses Windows Service to match all stored schedules, we can easily control its behavior by going to Service Runner section. In this section, you can Start, Pause, Continue and Stop this service based on your need. You can also use services.msc to do the same thing. If you inspect that the schedules that you have set don't play audio files, you can go to this section (or services.msc) to see whether or not this service is paused or stopped.
