Shut down with timer or after finishing a job automatically, with WinExit
WinExit is a free utility that will let you shut down Windows with a double click.
Besides this, you can configure shutting down using various options, such as a timer or alarm trigger — you can let your computer finish a certain task, before it shuts down.
WinExit can also log usage time, and perform some cleanups during shut down.
WinExit appears as a Stop sign in the task bar. Right click opens a menu with all the options, to choose the preferred way to shut down your system (Power off- or Force- shut down is recommended).
