Task Scheduleris a component of Microsoft Windowsthat provides the ability to schedule the launch of programs or scripts at pre-defined times or after specified time intervals:job scheduling(task scheduling). It was first introduced in theMicrosoft Plus!forWindows 95 as System Agent but was renamed toTask Scheduler in Windows 98. The Windows Event Logservice 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. Column 'Last Result' The Last Result column displays a completion code. The common codes for scheduled tasks are: 0 or 0x0 The operation completed successfully. 1 or 0x1 Incorrect function called or unknown function called. 2 or 0x2 File not found. 10 or 0xa The environment is incorrect. 0x41300 Task is ready to run at its next scheduled time. 0x41301 Task is currently running. 0x41302 Task is disabled. 0x41303 Task has not yet run. 0x41304 There are no more runs scheduled for this task. 0x41306 Task is terminated. 0x8004131F An instance of this task is already running. 0x800704DD The service is not available (is 'Run only when a user is logged on' checked?) 0xC000013A The application terminated as a result of a CTRL+C. 0xC06D007E Unknown software exception.
