Sometimes you have to schedule tasks if you cannot do them manually. One example is shutting down (or restarting) your computer after a certain amount of time or on a specific time. It is useful especially when you are downloading large files or watching on your PC, and you do not want to leave your machine running for a long time.

Enter the following:
shutdown -s -t 1800
The value 1800 represents the number of seconds that your operating system will countdown. In this example, we are counting down from 30 minutes. Experiment with different values until you set the length of time that you want. Click OK, and you are set to go.
