2 Ways to Set up timer to Shut down PC automatically for Free

Yesterday night, I was watching a movie, I don't know if the movie was so boring or I was feeling to tired and as a result, I fall asleep and started enjoying my dream and the PC remain turned on for the whole night. When I woke up in the morning, Damn!! I forgot to shut it down.
    This is not only my story if I am not mistaken. While surfing through the internet I came out with some option to set up timer for shutting down the pc automatically. Lets start;

Method one:
    This is the most easiest way here and you don't need to download any software for it. As me, if you are watching a movie then just calculate the total duration of the movie and convert it to seconds.

For example, if you are watching a movie of 1 hour and 30 minutes then just convert it into seconds. Here, 1 hour 30 minutes becomes 60+30=90 minutes ( because 1 hour = 60 minutes)
Multiply 90 by 60 to get it in seconds i.e. 5400 seconds

• Go to Start > Run
• Type shutdown -s -t 5400 and hit enter

Here, 5400 is duration of the movie in second which we calculated in the previous steps.
You will see a dialogue box as below, You are done!!

What if I want to stop the shut down process? :/ 

If this is the problem then just,

• Go to Start > Run
• Type shutdown -a and hit enter.

Method Two:
You can also use timer software to set up scheduled shut down timer for your PC. I found a freeware named Switch Off, you may give a try.

• Download Switch Off here and install it.
• View Switch off screen shots for more information and using tutorials.

That was it, Cheers !!
