Microsoft Office Outlook Rules are not just for managing or finding your old email messages. Tim Matheson has a unique idea to shutdown any Windows Computer using an email or a text SMS message. For the remote shutdown to work, your PC must be connected to the internet and Microsoft Outlook should be running to receive emails.
Basically you setup a rule in Microsoft Outlook to look for say a keyword (like SHUTDOWN PC) in the subject line of an email. Then you select run application as the action for when that keyword is found. Then all you have to do is write a simple DOS batch file and use the shutdown command with the -f parameter.
Just a little correction here, you may want to add the -s switch to the command shutdown -f -s as using only the -f switch may cause the computer to log you off without actually turning off.
Also, the Outlook Rules Wizard allows you to "run a script" when you create a specific rule. As a developer, this allows you to perform an action on incoming mail that is not possible using the regular features of the Rules Wizard. More on this here.
