How to Increase Computer CPU Speed

By Cameron Easey

The processor in your computer is used to run many types of applications in addition to the operating system that is installed on the machine. When programs or services load at startup they will use various amounts of processor power to complete a particular task. If your computer runs slow or is taking a long time to load programs, you can boost its performance by increasing the CPU speed.

Change CPU Priority of Running Programs

Step 1

Press the "Ctrl + Alt + Del" keys on the keyboard to display the Windows Task Manager.

Step 2

Go to the Processes tab. Observe the CPU column to see how much CPU usage is needed by running programs.

Step 3

Right-click on a program that has high CPU usage, such your web browser. Select the "Set Priority" option.

Step 4

Click "BelowNormal" or "Low" to change the CPU priority of the program. Click the "Change Priority" button when the confirmation box appears.

Step 5

Repeat this process for other programs that have high CPU usage.

Turn Off Indexing Service

Step 1

Click the Start button and then select the "Computer" or "My Computer" option. Right-click on the Local Disk (C:) and select the "Properties" option.

Step 2

Go to the General tab. Uncheck the "Allow Indexing Service to index this disk for fast file searching" option.

Step 3

Click the "Apply" button to save the change. Click the "OK" button to close the Properties window.

Step 4

Select the "Apply changes to C:\" only or "Apply changes to C:\, subfolders and files" and click the "OK" button.

Step 5

Wait while the system changes attribute settings to all of the files.

Tips & Warnings

  • Setting programs to a lower priority setting will prevent them from using 100% of the CPU, which can increase its speed.
  • CPU priority for running programs will reset when you close and restart the program.
