How to schedule a shutdown on Windows

Sometimes could be useful shutdown Windows at certain time... there are many ways:

Command method:

Open a command prompt as administrator and write:

 shutdown -s -t SECONDS

where SECONDS are the time in seconds to the shutdown (remember 3600 seconds = 1 hour)

 shutdown -a 

to reset and delete the countdown.
When you set/delete the shutdown a pop-up notification notices you.
The -f option to force programs to close is useless in this case because if -t is set with a value >0 -f is implied.

Task scheduler:
Press Win and search for "schedule task" to start Task Scheduler. You can create a new task to shutdown the pc at a certain time. Use basic task wizard.

Other softwares:
There are tons of tools for this task... I suggest you Simple Shutdown Scheduler

Remember: with the Command method you can shutdown remote pcs too!
