How to Fix High CPU Usage?

A processor or CPU is one of the necessary elements in a computing device supervising all the other connected elements. But we often use it beyond its capabilities which isn’t a good utilization of such an important rig’s element. If it’s happening a few times, you’re good to go. However, if you regularly observe CPU use remaining at a high level (80% or more) for extended periods of time, your system or application’s performance will suffer. For this reason, it’s critical to comprehend the root cause of persistently high CPU utilization in order to identify and, if possible, resolve the issue.

If you are facing the same issue, don’t worry since you’re not the only one who encounters this issue. This is a common incident that has happened to many users around the globe so the manufacturers are also aware of this fact. The good news is that it’s pretty simple to solve this problem. If you are wondering about how to fix high CPU usage, then look no further as this is the place where all your queries will be solved. We have written this article to assist you in finding the root of persistently excessive CPU consumption. You must read this post until the end to better know the issue. 

Why CPU usage is high? Check it first. 

Try using Task Manager to see which activities are hogging so much CPU utilization when you discover that your PC is running slower than usual and that it is at 100% CPU usage. Here’s how to go about it:

Step 1: To launch Task Manager, press Ctrl, Shift, and Esc on your keyboard. Permission will be requested from you. To launch Task Manager, select Yes.

Step 2: To arrange the processes by CPU utilization, click the CPU column header. You can now see which processes are using up your CPU.

Step 3: Choose the process that uses the majority of your CPU, and then click End task to end it.

After terminating all CPU-intensive processes, check to see if the CPU use is still 100%. If not, congrats to you! This problem has been fixed by you. Try the next solution if the problem still exists.

Few more methods to fix high CPU usage

Update your drivers

Try upgrading your drivers if a process is still consuming too much CPU power. Drivers are software applications that manage certain devices that are attached to your motherboard. Your drivers may need to be updated to fix compatibility problems or defects that lead to higher CPU utilization. Follow the steps described below to check if you have outdated drivers and how you would be able to update them:

Step 1: Go to Settings from the Start menu.

Step 2: After selecting Updates & Security, click “Check for Updates“.

Important drivers will be updated by this. Your BIOS version may also be updated to address any uncommon issues. When a computer starts up, the motherboard’s firmware known as the BIOS (Basic Input Output System) sends commands to the other components. Only do this if you have found the bug causing high CPU utilization and located a BIOS update that directly fixes it, as updating the BIOS typically doesn’t result in performance improvements (and can introduce new issues).

Malware scanning

If the problem still exists, spyware that poses as a standard Windows process may be to blame. Some malicious apps show in Task Manager with familiar names like “Cortana.exe” or “Runtime Broker“, but they are actually consuming CPU and GPU bandwidth for other purposes (like cryptocurrency mining, for example). To check for this, do a thorough virus scan using your chosen application. One excellent choice is the free offline security scan offered by Windows Security (running on your taskbar or Windows settings). Follow the steps:

Step 1: Click Windows Security.

Step 2: Now click on Virus & Threat Protection.

Step 3: Now select a quick scan.

Step 4: If you encounter any viruses or malicious software click start actions and windows will remove them.

Power Options

Whether you’re using a laptop or a desktop, some power settings can restrict the speed of your CPU. 

Step 1: By selecting the Start button and typing “Edit Power Plan“, you may view your power options. 

Step 2: Click “Power Options” in the address bar at the top of the window once it has opened. You ought to see this display:

Step 3: A non-power saving plan can then be enabled by selecting “Show additional plans“.

Step 5: Check to see whether CPU utilization returns to normal by opening Task Manager once more.

Reinstalling windows

If you have a restore point from before your CPU problems started, consider utilizing it. However, most of us don’t because Windows disables System Protection by default. Then, reinstalling Windows might be your only option. This may take a while, but it might be able to fix software-related CPU utilization problems. All of your programs will be uninstalled via Windows 10’s “Reset this PC” feature, but your private files will remain intact. 

Your settings in all of your non-Windows apps will be lost if you don’t save and back them up before you have to reload them all. Backup all of your personal files as well, whether on an external disc or online, just in case. When you’re ready to get started, click Start and enter “Reset this PC“, Click “Get Started” after that.


High CPU utilization is one of the simplest issues that can impair a computer’s performance. Finding the source of the issue and knowing how to fix high CPU usage might also be challenging if you don’t know what to look for and where to look. You could only need a faster machine if you see that excessive CPU use persists even when supporting ordinary processes. You can reduce the workload on the CPU by expanding RAM, which enables your computer to store more program data. This can give your CPU a much-needed break by reducing the frequency of internal data transfers and new memory allocations.

The methods described in this article should resolve your high CPU usage issue. First of all, you must check whether the CPU usage is in-real high, or your chip is lagging due to some other reasons. Then, make sure that you follow each step properly and act according to the guidance provided above. If even still the issue persists then you may want to consider your hardware. Often there are compatibility issues when you use components of other companies which are unable to optimize and hence there are errors. So try upgrading and contacting a professional to resolve all issues. We hope this article helped you resolve your query.
