Windows Task Scheduler
Task Scheduler is a component of Microsoft Windows that provides the ability to schedule the launch of programs or scripts at pre-defined times or after specified time intervals. It was first introduced in the Windows 95 Plus! pack as System Agent but was renamed to Task Scheduler in Windows 98. The Windows Event Log service must be running before the Task Scheduler starts up. This service should not be confused with the scheduler that allocates CPU resources to processes already in memory.
