To create time windows on successive days
In the Start Window tab of the New or Change Schedule dialog box, position the cursor over the day and time when you'd like the first time window to begin.
Press and hold Shift on the keyboard. With the left mouse button, drag the cursor to the time that the first time window is to close. Continue to press Shift.
Drag the cursor down to duplicate the window on successive days.
