Windows operating systems provide the shutdown command in order to shut down or reboot a computer.

Reboot/Restart Windows Computer with Delay

But in some cases, you may need more time where you can set the delay with the /t option. This option is called a timeout. In the following example, we will set the reboot/restart delay as 120 seconds which will be enough for most of the cases.

C:> shutdown /r /t 120
