Shutdown Computer within 5sec

If you want to shut down your computer in a hurry, or if a frozen application prevents you from shutting down in the normal ways, then you can use the following procedure to Shutdown your computer.
This method is absolutely safe, but you won’t get even a single opportunity to save your open documents.

To perform this emergency shutdown, press Ctrl+Alt+Del to display Task Manager.
Open the “Shut Down” menu and hold down the Ctrl key and click Turn Off. Poof! your system is Off within Seconds. You don’t even get a second thought to think upon.
