SchTasks.exe performs operations similar to those in Scheduled Tasks in Control Panel. You can use either tool to create, delete, configure, or display scheduled tasks. The user must be a member of the Administrators group on the computer that the command affects. To verify that a scheduled task ran or to find out why a scheduled task did not run, see the Task Scheduler service transaction log, Systemroot\SchedLgU.txt. This log records attempted runs initiated by all tools that use the service, including Scheduled Tasks and SchTasks.exe. On rare occasions, task files become corrupted. Corrupted tasks do not run. When you try to perform an operation on corrupted tasks, SchTasks.exe displays the following error message: ERROR: The data is invalid. You cannot recover corrupted tasks. To restore the task scheduling features of the system, use SchTasks.exe or Scheduled Tasks to delete the tasks from the system and reschedule them
