System Scheduler System Scheduler (previously known as "Windows Scheduler") is an excellent tool to schedule unattended running of applications, batch files, scripts and much more. For anyone used to using MSTask, AT or WinAT, System Scheduler is an ideal and easy to use replacement, with more flexibility and features. Also, you can schedule popup reminders so you'll 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.

System Scheduler not only allows you to launch programs at scheduled times but also to send keypresses 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.

System Scheduler also has 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 when 'error messages' appear while you are away.
