Shutter is an application for the programming and control of the PC shut down, which lets you leave a series of actions programmed, like shut down, reset or suspension of the PC, activate an alarm or switch off the monitor. These actions are done when a set of predefined circumstances occures: a set hour, a countdown, or a certain level of CPU use.
Finally, one of the most interesting options you`ll find in Shutter is that you can program an action to run when a song playing in Winamp finishes.
