taskmgr

Task Manager, often referred to as taskmgr, is a system utility that provides information about the programs and processes running on a computer, as well as the performance of the operating system. It allows users to view and manage running applications, processes, and services. Task Manager can be used to end unresponsive programs, monitor CPU and memory usage, and identify potential performance bottlenecks.

Accessing Task Manager varies depending on the operating system. On Microsoft Windows, it can typically be opened by pressing Ctrl+Shift+Esc, or by right-clicking the taskbar and selecting "Task Manager." The interface is generally divided into several tabs, such as Processes, Performance, App History, Startup, Users, and Details, each offering different insights into the system's operation.

The Processes tab lists all running applications and background processes. Users can see resource consumption for each, such as CPU, memory, disk, and network usage. This is useful for identifying applications that are consuming excessive resources. The Performance tab provides graphical representations of key system metrics like CPU, memory, disk, and network utilization over time.

The Startup tab, present in newer Windows versions, allows users to manage which programs automatically launch when the computer starts, which can significantly affect boot times. The Users tab shows which users are currently logged into the system and the resources they are consuming. The Details tab offers a more in-depth view of processes, including their process ID (PID) and command line. Task Manager is a fundamental tool for system administration and troubleshooting.
