   • Exit a program: To exit a program, click the program that you want to exit, and then click End Task.

     Note: When you exit a program in this manner, any unsaved data in that program is lost.

   

   • Start a program: To start a program, click File > Run new task. In the Create New Task dialog box, click Browse, locate and select the program that you want to start, click Open, and then click OK.

How to end a process

   • If you want to end a process and all processes directly or indirectly related to it, right-click the process that you want to end, and then click End Process Tree.

Note: Proceed with caution when you end a process. If you exit a program in this manner, data that has not been saved will be lost. If you end a system process, a system component may no longer function correctly.

How to monitor your computer's performance

Click the Performance tab to view a dynamic overview of the performance of your computer. Below is an overview of the performance tab.

CPU CPU usage graph total number of handles, threads, and processes that are running (Handles are unique identifiers that allow a program to access system resources such as files, registry keys, fonts, and bitmaps. Threads are objects within processes that run program instructions.)
Memory memory usage graph total amount of memory in use and available amount of committed memory amount of cached memory memory speed
Disk disk usage graph read/write speeds active time and average response time disk capacity (size)
Connections upload and download speeds connection information (adapter name, domain name, connection type, IP address) This image shows the Ethernet tab. Machines with additional connections (e.g. WiFi, Bluetooth) will have additional tabs.

How to manage your startup programs
