Are you having a CPU 100% usage even though you are not doing anything on your computer?

You’re not probably the only one who’s having the issue. Many Windows 10 users reported that they have experienced the same.

Don’t worry, I’ve got a few fixes for you to get this issue resolved.

Step 1: Check your Security Programs

Having more than two security programs could hurt your system. Thus, you will be having a 100% usage issue. You could pick the best antivirus that you think is worth keeping.

I would suggest keeping the reliable one and you could keep another one. Make sure the second one is lightweight that does not consume much of your system resources.

The second one will serve as your second layer of protection.

Step 2: Reset your Power Settings

Check if the power option of your machine is not set to Power saver. Power saver is useful when you need to finish something and you don’t have a little power left. However, when you forget to reset the option to a Balanced option can affect the performance of your system.

  1. Please go to your Start and type: Power Plan
  2. Click Choose a power plan
  3. Select Balanced option

(You could also click the Restore default setting for this plan)

Step 3: Disable Unnecessary Startup Programs

Some programs that you install will automatically set itself to run every time you startup your computer. But, most of these programs are not necessary to run on your startup. You could choose a program that needs to run at startup such as your antivirus.

You can check your startup programs and only run those ones that need to run.
