Introduction
Timer Computer Shutdown application provides functionality to shutdown, restart, stand by, hibernate or log off supported computers, at a selected date and time that has yet to elapse. Functionality of the shutdown modes has been provided by a WindowsController.cs class from http://www.mentalis.org/soft/class.qpx?id=7
WARNING: The "Brute" option will force termination of all running processes, any unsaved data will be lost; guaranteeing a shutdown. This option has been designed to close applications which produce a prompt upon closing.
