System Scheduler runs totally independently of the MS Windows Task Scheduler and has no dependencies on it. You can schedule popup reminders so you will never forget those important appointments and things to do. Reminders, tasks, and other events can be set to run once or every minute, hour, day, week, month, or year and several variations on these. Popup Reminders can be snoozed as required. System Scheduler not only allows you to launch programs at scheduled times but also to send keypresses and mouseclicks to those programs. This allows you to not only schedule programs to run overnight or at the weekend but also get those programs to do useful things while unattended. The Free version of System Scheduler also includes a Window Watcher feature. The program will check for the existence of a particular window and send keypresses or send the window a close signal to terminate running applications. Useful for triggering actions or handling error messages while you are away.
