AutoShutdown is a Windows-system shutdown manager. The software provides unattended control for a Windows PC; you can shut down, restart, log off, stand by, or hibernate based on the date or time, idle computer time, hot keys, or a manually triggered command. AutoShutdown also can monitor the battery level in a notebook computer and act while there's still power available. Systems running Windows 2000 and XP can lock the workstation. Version 4.5 adds a new scheduling system and a service module.
