SleepWalker - More than a simple shutdown utility
Sleepwalker has been designed as a fully-automated shutdown timer with multiple power management capabilities. However, it is more than a simple timer: it supports multiple power-related actions, and, at the same time, is able to perform some cleaning on your computer.SleepWalker has been conceived as a monolithic application, with only one critical file: the main executable. Unlike other shutdown-related products, SleepWalker does not rely on additional memory-consuming services and intricate applications.
"The solution allows you to program computer shutdown/restart/hibernate, user log off, running the screensaver, or a user-defined file with absolutely no problem. The application can also be used to assign shortcuts to these actions to be performed on the spot. In case of processes hanging, SleepWalker can force the computer to obey the predefined action."
