How to Fix High CPU Usage in Windows 11?

One of the most common symptoms of high CPU usage in Windows 11 is severe lagging and a dip in the overall functioning of the computer. Higher the CPU usage, the higher the chances of your system crashing, lagging, hanging, or crashing altogether. 

The more power your CPU consumes, the faster your system fan will have to function, and the faster it functions, the more it is likely to fail. As we mentioned earlier, there is no one common reason as to what causes this problem in Windows 11. 

Therefore, below are a list of solutions to fix high CPU usage in Windows 11. These fixes are generally aimed at solving the common causes of the issue. 

Note: The fixes mentioned below are arranged as per the severity of the issue. Therefore, it is vital that you apply these fixes serially and do NOT jump directly to the final step. Doing so is likely to result in damage to Windows 11 altogether. 

1. Restart Your System

There is nothing a quick restart cannot fix. Though it is a temporary solution, restarting your system can cause the PC’s services to reboot and go back to normal. Once your system starts, you can check your CPU usage once again using the steps mentioned above. 

Also, you will be able to identify the root cause of the problem or even the program or application that can be causing the problem. Now, check to see if the CPU levels have dropped down. If not, continue to apply other fixes. 

2. End/ Restart Processes

When you check your CPU usage, you will see the CPU consumption of a particular application, program, or service consumes. In such cases, your best bet is to either end or restart a process consuming heavy memory altogether. To end/restart operations in Windows 11, follow the given steps.

  1. Close All Running applications
  2. Right-click on your Start Menu and select Task Manager
  3. Here, you can see the CPU Usage next to each running application under the CPU Column
  4. Look out for apps that aren’t in use at the moment but are consuming a significant amount of CPU memory
  5. Right-click on the service/application
  6. Click on End Task

Repeat this process to end tasks that aren’t in use but are eating a chunk of your CPU memory. Also, note that CPU usage is generally higher when playing high-definition games, streaming a video application, or running video-editing software. In such cases, it is best if you close all your background apps and focus on just a single application at a time. 

3. Stop Background Applications

Irrespective of your system’s operating system and overall specifications, running too many applications in the background is never a smart move. The more applications you have running in the background, the more memory the CPU has to distribute to different locations. 

This can lead to the primary application or service receiving less than the required memory to function. Similarly, some of the background applications can be heavy, ultimately leading to heavy CPU usage in Windows 11.

In such cases, stopping all the background applications on your system can do the job. To stop background applications on Windows 11, follow the given steps.

Note: There’s a fundamental difference between multitasking and starting/stopping apps. Also, note that in Windows 11, you have to stop each background application individually.

  • Close all running applications
  • Right-click on Start Menu & Select Settings
  • Go to Apps > Apps & features
  • From the apps given, locate the apps you don’t want running in the background and Click on the three vertical dots in front of the app
