How to Clean Up CPU Usage

By Mikhail Polenin

When you open an application on your computer, it shares your central processing unit's power with all the other applications already open on your computer. When your computer has high CPU usage, one or more applications try to compete for the resource in order to finish processing input. Sometimes, an application might demand CPU power because of an error that causes it to infinitely process a piece of data even when it's finished.

Step 1

Press "Ctrl," "Shift," and "Esc" on your keyboard to bring up the task manager on your computer instantly.

Step 2

Click the "Processes" tab to view all your applications.

Step 3

Click the "CPU" column until a down-pointing arrow appears above the column label.

Step 4

Right-click programs that you recognize, which use the most percentage of your CPU's power and click "End Task." Click the "End Task" button on the new window to confirm the termination.

Tips & Warnings

  • Only close programs you recognize. If you do not recognize a program, you might accidentally close an important process in your operating system.
