What is Task Manager?
Task Manager shows you the programs, processes, and services that are currently running on your computer. You can use Task Manager to monitor your computer’s performance or to close a program that is not responding.
If you are connected to a network, you can also use Task Manager to view network status and see how your network is functioning. If more than one user is connected to your computer, you can see who is connected, what they are working on, and you can send them a message.
