The reason is because I have a number of programs I want to run in order to help ensure the computer is cleaned "Virus checking, adware removal, updating, removal of old files, etc.. and I want to run them in like how a CGI Cron Job works.. And have this done at night while I am sleeping and then have the computer turn off automatically at the end because the computer draws a LOT of power to have left on over night when not being used.
