Task Manager

Task Manager is a new tool introduced with Windows NT 4.0. It lets you monitor active applications and processes on your computer, and start and stop them. It also has basic performance-monitoring capabilities.

Task Manager offers the following features:

• It displays running applications and processes, including 16-bit processes.
• It displays the most commonly used performance measures for processes, including microprocessor time, main memory size, virtual memory size, page faults, base priority, and number of threads.
• It displays line graphs and instantaneous values of microprocessor and memory use for the computer.
• It lets you set microprocessor affinity for a process, change the base priority class of a process and activate a debugger, if you have one.

Task Manager gets its data from the same functions used by Performance Monitor. However, it calls these functions directly, bypassing the Performance Library and the registry. Thus, it cannot log data to a file and it cannot monitor remote computers. However, it is a useful tool for quick checks of basic counters and for training users to monitor their own computer.
