Task manager

A task manager is a system monitor program used to provide information about the processes and applications running on a computer, as well as the general status of the computer. Some implementations can also be used to terminate processes and applications, as well as change the processes' scheduling priority. In some environments, users can access a task manager with the Control-Alt-Delete keyboard shortcut.

Process Hacker is a free and open-source task manager for Windows. It has some features which some competitors do not; for example, it can change a process's I/O priority.

Task managers can display running services (processes) as well as those that were stopped. They can display information about the services, including their process identifier and group identifier.
