System Scheduler Professional 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 Professional version of System Scheduler features terminal services or remote desktop support and support for MS Windows own Auto Logon feature.
