How To Fix High CPU Usage Issues On Your Windows Computer

Feeling irritating when one or more system processes is hogging your CPU resource, such as svchost.exe (netsvcs) or the WSAPPX process? It’s not a problem anymore if you know how to diagnose and troubleshoot.

Therefore, in this post, I will explain further about why those Windows system processes use a lot of your CPU resource. Besides, I’m going to share with you a few simple methods you can use to diagnose and troubleshoot.

Why svchost.exe, tiworker.exe or WSAPPX causes high CPU usage issue?

Typically, these Windows system processes only use a few percents of your total CPU resource. Sometimes, it could raise up a bit, but never greater than 10% and won’t last long.

However, if something goes wrong with those processes, they could use up to 100% of your CPU. As a result, your computer will slow down, and you can’t use it with a good performance.

What should I do to diagnose and troubleshoot?

Before applying any methods, you need to determine why this issue occurs on your Windows PC. Then take a proper solution based on that result to troubleshoot.

Two best tools can help you find out why those system processes cause the high CPU usage problem: Process Explorer and Task Manager.

Basically, both tools work the same, but I prefer Task Manager because it exists in Windows. You don’t need to download to use, just press Ctrl + Alt + Del on your keyboard and select Task Manager.

In Task Manager, locate the process that is hogging the CPU resource, then right-click on it and choose “Go to service(s)” option. This step will highlight all Windows services that are related to the selected system process.

For example, if you found that WSAPPX process caused this high CPU error on your PC, use method above, you will see that this system process belongs to Windows Store.

In this case, you can try to restart Windows Store service to get rid of this high CPU error. I have used this method a few times, and it helped me to resolve this annoying issue. You can also disable this service to fix the problem if you want. However, after disabling, you won’t be able to access Windows Store to search for apps anymore.

What is the general method to resolve high CPU error in Windows?

There would be no all in one solution to help you deal with this type of Windows errors. However, in most cases, the program or Windows feature that stands behind those system processes is corrupted, or something goes wrong with it. As a result, this high CPU error occurs and slow down your Windows computer.

So if you look for a place to get started, begin to find out which program, feature or service that stands behind the chosen system process. Then use a proper method to resolve it.
