The Scheduling tab allows you to specify when the automatic tuning job should run and how often.
Under Daily, you can use the Weekdays settings, for example, to specify that the computer should only carry out the tuning job on workdays or just every other day, or on weekends only, when it is not being used for work. To change date and time entries under Time, simply highlight the element you want to change (e.g. day, hour, month, year) with the mouse and use the arrow keys or the small arrow icon to the right of the input field to move the relevant element chronologically.
If you do not want to run an automatic tuning process, just remove the check from the box next to the Enabled entry for the automatic tuning process.
