The task manager under Vista has seen some good improvements, mainly in the nature of the data it exposes to the user. For example, apart from the usual processes, the task manager now also displays the list of services running on the system. Another great addition to the Task Manager can be found under the Performance tab—the Resource Monitor. The Resource Monitor is an invaluable tool to keep a tab on the health and status of the system. It displays historical data and ongoing data of the system based on several sub-systems: the CPU, the disk, the network, and the memory. For each of these sub-systems, the Resource Monitor displays which system files or processes are chewing through the same. Thus, if you were to click on the CPU section, it would list down all the processes that are currently using the processor along with data on which process or file is using the most processor time. Similarly it shows information on RAM usage, disk usage, and network usage. To start the Task Manager, press [Ctrl] + [Shift] + [Esc]. You can then move to the Performance tab and click on the Resource Monitor button to launch the Resource Monitor. To exit a program which is not responding, select it under the Applications tab and click on End task
