Task Scheduler (control.exe schedtasks) 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[1] 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.Task Scheduler 2.0 was introduced with Windows Vista and included in Windows Server 2008 as well.[2] The redesigned Task Scheduler user interface is now based on Management Console. In addition to running tasks on scheduled times or specified intervals, Task Scheduler 2.0 also supports calendar and event-based triggers, such as starting a task when a particular event is logged to the event log, or when a combination of events has occurred. Also, several tasks that are triggered by the same event can be configured to run either simultaneously or in a pre-determined chained sequence of a series of actions, instead of having to create multiple scheduled tasks. Tasks can also be configured to run based on system status such as being idle for a pre-configured amount of time, on startup
