Symptoms

Consider the following scenario:

  • You schedule some tasks in Task Scheduler to run daily, weekly or monthly on a computer that is running Windows 7 or Windows Server 2008 R2.

  • You clear the check box for the Run task as soon as possible after a scheduled start is missed option in the Task Properties dialog box.

  • The computer enters sleep or hibernation during the scheduled task. Then, you resume the computer from sleep or hibernation after the scheduled task.

In this scenario, the Task Scheduler runs the task.

Cause

This issue occurs because Task Scheduler runs tasks regardless of the Run task as soon as possible after a scheduled start is missed option.
