How to Remove Unwanted Computer Processes

By Catherine Hewson

Most users install new programs on their computers without first getting rid of old, unused programs first. This slows computers dramatically, because unwanted programs use too many system resources. Removing unwanted processes is an absolute must to keep computers running faster longer.

Step 1

Go to “Start>Settings>Control Panel>Add/Remove Programs.” Select a program that you no longer use, and click “Uninstall.”

Step 2

Delete the program folders. Go to “My Computer,” and navigate to “C:\\Program Files.” Then simply delete the folders for the old programs.

Step 3

Reboot the computer.

Step 4

Download and install a program, such as the free Process Explorer or WinPatrol, that will delete or suspend unnecessary processes. If you don’t want to use a process remover program, skip to Step 7 for manual process removal instructions.

Step 5

Open the process remover program. Find processes that you do not need.

Step 6

Right-click a process, and select “Kill Process” to delete. To temporarily disable a process, select “Suspend Process,” and exit the program. Suspending a process will allow it to return when the computer is restarted.

Step 7

Press “Ctrl-Alt-Delete.” When prompted, select \"Start Task Manager.\" This will pull up Windows Task Manager.

Step 8

Click the “Processes” tab to browse through running processes. When you find a process you want to get rid of, simply click “End Task.” Then click the “Exit” button to get out of Windows Task Manager. Note that most of what is listed are Microsoft processes, which are necessary for for the computer to run safely, so be careful in selecting processes to delete.

Tips & Warnings

  • Do not delete processes if you don’t know what they do. Many users make this mistake, which causes the operating system to become unstable and crash. When in doubt, ask someone on a PC forum for advice (see Resources).
