Task Manager

Task Manager provides information about programs and processes running on your computer. It also displays the most commonly used performance measures for processes. You can use Task Manager to monitor key indicators of your computer's performance, and you can quickly see the status of the programs that are running and end programs that have stopped responding. You can also assess the activity of running processes using as many as 15 parameters, and see graphs and data on CPU and memory usage.
