How To Fix svchost.exe High CPU Usage Permanently

There are many services that are running in the background whenever you are making use of your computer.

An example of this is the Svchost.exe which can sometimes lead to High CPU usage.

Also referred to as Service Host, the Svchost.exe is very important as it hosts other services on your computer, so you cannot just stop it when it causes a problem. Nonetheless, when it keeps causing high CPU usage, what happens is that it denies others of the needed resources and so the performance of your computer will drop drastically.

What is svchost.exe?

Contrary to what some believe that the program is a virus, it is not. It was introduced by Microsoft since the time of Windows 2000 to serve as a host for other windows services. If you go to your Task Manager and check the processes running, you will see a number of svchost that all share in this function.

There are a number of problems that could lead to high usage of CPU as a result of this program such as virus attack, Windows update problems, corrupted system files, or other things. If you start having the problem, you may start experiencing your computer slowing down, freezing, failing to take commands, or even return with the blue screen of death (BSOD).

However, the good news is that this issue can be solved by simply following some methods we have provided below.

Updating your Windows is something that is able to solve a lot of issues you are having with your computer because each update is aimed at fixing bugs that could cause a problem to your computer.
