Active Task Manager is a compact automaton tool to set up and run unattended tasks. It helps you to manage your frequent tasks and starts them in background. It starts the .exe, .bat and .com files, shuts down the system and displays text-sound reminders at scheduled moments or manually. The flexible scheduling capability allows you either to set time interval between the consequent starts of a task, or specify exact start times within a day, week or month. You can set a process priority and a CPU affinity mask for a task. Running as a Windows service, this software runs the scheduled tasks even on a logged off computer. The tray icon menu lets you start any task manually. Other applications can interact with ATM via ActiveX Automation. This tool occupies system resources minimally. Ample documentation is also available.
