How To Resolve High CPU Usage Issue On Windows Computer

According to the recent statistic, Microsoft's Windows is one of the most popular operating systems for computers, alongside the Mac OS X and Linux. Many users are very familiar with this operating system because it has a simple user interface, easy to use and more importantly, there were a lot of apps you can quickly find, download and install to use. Those reasons make Windows to be a perfect operating system for most of the users, including you and me.

However, along with those good reasons, Microsoft's Windows also has some bad points, like irritating errors, including high CPU or RAM usage issue, especially when it comes from svchost.exe (netsvcs) system process. You may know that svchost.exe is a system process of Windows operating system, which often use to run functions in the DLL library files. Those files themselves couldn't run directly. Instead, they will need assistances from svchost.exe to help them execute those functions.

What Should You Do When Encountering High CPU Usage Issue?

When dealing with this irritating error, you will need to figure out which system process is hogging your processor resource. The simplest solution to finding out is that uses Task Manager.

When you launch Task Manager, look at the CPU column, you will see how much CPU resource was used, as well as how much left. In case it was a program, you can quickly force it to quit and re-open it. With this move, the program will be refreshed and back to normal status. I often use this method when my Firefox browser somehow starts to use too much CPU resource on my computer. A refresh did help me to solve the issue.

However, when it was a system process like svchost.exe, smss.exe, or lsass.exe, closing it won't help you to resolve this high CPU usage issue at all. Instead, you will need to figure out the real cause and fix it from the root. In case you don't know, there was an application for Windows, called Process Explorer. It similars to Task Manager but comes with more advanced features, which will help you to find which program or service stands behind each system process.

For example, if svchost.exe was caused this issue, you will find out where it came from, which program or service was used it to execute functions. Although it won't help you to find detailed information, however, you can eliminate a lot of other causes and shorten the distance.

Methods To Resolve High CPU Usage Issue On Windows Computer

Many reasons can create a high resource usage error in Windows, including misconfigurations, corrupted files, or Windows updates. In order to find out, you can use Process Explorer as I mentioned above to determine the reason and then take an appropriate way to fix it. In this post, I will help you point out a few primary solutions that you can use to resolve high CPU usage problem on a Windows computer.

When Windows Update gets a problem, it can cause this kind of high usage error on your Windows computer.
