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.
Works as the Task Scheduler should. Has all functionality including customizable success and failure alerts emailed for sysadmin functions.
Cons
I have not found a downside at this time.
Summary
I had a situation where other items were working in the native 2008 server task scheduler however a task including "move" files never worked no matter however the permissions were set. That prompted me to look for third party solutions. This one has fulfilled that need. I have converted all those server tasks to System Scheduler Pro. Thanks.
