When scheduled tasks run, predetermined actions are triggered that can range from auto-updating installed programs to activating maintenance and security processes utilized by the operating system. Certain scheduled tasks set by third-party programs require a considerable amount of system resources that may cause performance issues when triggered. Use the Task Scheduler applet built into Windows 8 to stop an unwanted task from running as scheduled.
