Windows Task Manager is a task manager application included with Microsoft Windows operating systems that provides detailed information about computer performance and running applications, processes, network activity, logged-in users, and system services. The Task Manager can also be used to set process priorities, forcefully terminate processes, and shutdown, restart, hibernate or log off Windows. A rudimentary Task Manager albeit different from the one present in the Windows NT-family of operating systems is present in Windows 95, Windows 98 and Windows Me although it is only useful for launching and terminating programs.

Security issues

Task Manager is a common target of computer viruses and other forms of malware; typically malware will close the Task Manager as soon as it is started, so as to hide itself from users. Variants of the Zotob and Spybot worms have used this technique, for example.[1] Using Group Policy, it is possible to disable the Task Manager. Many types of malware also enable this policy setting in the registry. Also, certain types of malware can prevent themselves from getting listed in the Task Manager, and thereby prevent their termination.

  • By right-clicking on any process, it is possible to directly open the Properties of the process executable or the directory (folder) containing the process.
  • The Task Manager has also been made less vulnerable to attack from remote sources or viruses as it must be operating under administrative rights to carry out certain tasks, such as logging off other connected users or sending messages. The user must go into the "Processes" tab and click "Show processes from other users" in order to verify administrative rights and unlock these privileges. If the user is not an admin, they must enter a password for an admin account when prompted to proceed.
  • By right-clicking on any running process, it is possible to create a dump file. This feature can be useful if an application or a process is not responding, so that the dump file can be opened in a debugger to get more information.
