In Windows 11, unlike what happens with televisions and certain electrical appliances, there is no scheduled shutdown mode within its configuration options.
The closest thing to this function is the sleep mode or hibernation mode of laptops that reduce energy consumption, but they are not very useful for long periods of complete inactivity in which it is preferable to keep the computer turned off.
Fortunately, there are third-party programs that efficiently fulfill their task of automatically shutting down the system, either in periods when no activity is detected or at a pre-established time.
Windows 11 Task Scheduler
However, there is a quite effective option that is within the functions of Windows 11 and it is the Task Scheduler.
This function of Windows 11 allows you to schedule certain tasks, including the automatic shutdown of the system. These are the steps to follow.
