To duplicate or copy a time window to multiple days
In the Start Window tab of the New or Change Schedule dialog box, create a time window on one day.
Click and drag the time window to another day. Release Ctrl.
Immediately click Duplicate. The time window is duplicated to any days without existing schedules. Duplication stops when it reaches a day that already contains a defined schedule.
