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.

Step 2

Type “Schedule Tasks” (without quotes) into the search box and press "Enter" to open Task Scheduler.

Step 3

Double-click the task that you want to stop from the Active Tasks section. Next, click the “General” tab to find additional information about the task.

Step 4

Click “Disable” under the Actions section to stop the task from running.

Step 5

Press "Alt-F4" to close Task Scheduler.
