This question is relevant if you think about energy saving. Switch on and off frequently a PC may bring damages to the computer’s hard disk or the power supply. The best for your computer is keeping it on while you think you may need it. Reducing the on/off cycles is better for your computer health. However, keeping your PC fully on may be energy consuming.

Automatically, you may use your Windows scheduler application (Scheduled Tasks) and type into the run field a command like
C:\WINDOWS\system32\shutdown.exe [-parameters]

Stand-by
