How to Check Background Processesby Richard Klopfenstein
Background processes may be required for an operating system to run, but they can sometimes reduce performance by consuming too much of a CPU's attention. To determine if this is the case, you'll need to see which programs are actually running.
Checking a PC
Windows lists all the background processes using an application called Task Manager. To open it, press CTRL+ALT+ESC. The "Applications" tab will display normal programs that are open. The "Processes" tab will display background Windows process that are running.
Checking a Mac
Mac computers list all the background processes in an application called Activity Monitor. To open it, select it from the "Utility" sub-folder in the "Applications" folder. The Activity Monitor will show all processes and applications that are running.
Turning Off Processes
For Windows, select the application or process you would like to end in Task Manager, then click the "End Task" or "End Process" button at the bottom. For Macs, select the application or process you would like to end in Activity Monitor, and click the "Quit Process" icon on the top left.
