Objective
When troubleshooting a computer, it may freeze up and stop responding properly. If this happens, in Windows you can use the Task Manager utility to End Task on a program or process. You can also discover which processes are using the most memory and CPU cycles - which can sometimes indicate negative activity being performed by that item.
This article describes how to bring up the Task Manager utility, how to view which programs are running, how to tell which programs are using the most memory and CPU cycles, and how to End Task on an Application or Process. Using the Task Manager can free up a computer so normal troubleshooting can be performed.
