What’s A svchost.exe And Why Is It Using So Much CPU Help!

There are parts of Windows that are very cryptic to say the least. Probably one of the best examples is the svchost.exe. If you open your computer’s Windows Task Manager and look at the processes from all users you will likely see a number of these cryptic svchost.exe processes running on your computer right now. The svchost.exe or Service Host Processes are supposed to be there so don’t be alarmed.

The Service Host is part of Windows so you are not over ran with viruses or malware if you see them running. I’m not saying that you don’t have malware of course. Just that whether you have viruses and malware or not it is normal for the svchost.exe’s to be running. What they are is a gateway for services that are running on your computer like the Windows Update Service for example. These services attach to a Service Host in order to be able to do what they do in the background.

Looking At The Windows Task Manager For Problems

Windows 10 TaskMan The Windows Task Manager is a good friend to take advantage of. Whether you are using Windows 7 or before or you have Windows 8.1 or newer the task manager gives you a lot of information to help track down what kind of problems may be slowing your computer down. To make things easier you can even click on the CPU tab and it will list services by the amount of CPU percentage the processes are using. There are times when a Service Host may start taking up a massive amount of processor percentage and being able to track down what is going on is the only way to figure out how to actually fix the problem.

If you have used the Windows Task Manager and found out that it is indeed a Service Host that is using over 50% or even 100% of your computer’s CPU either slowing it down or making it virtually unusable the next step is figuring out what it that this particular Service Host is actually doing. Like I said before all types of Windows services and other services use the Service Host as their gateway so knowing what this Single Service Host is can be a daunting task.

Process Explorer┬áLuckily there is a free utility called Process Explorer. It is available for free by Microsoft at Technet so it is safe to download the file and run the program. With Process Explorer you can now look at what is hooked through the Service Host causing the problem and find out where to go next. Simply hovering the mouse cursor above the svchost.exe provides a list of the details. By right clicking on the svchost.exe you can access the properties of each service. One perfect example would be if the Windows Update Service suddenly started to use 50% or more of the processor percentage and didn’t stop. Using the Process Explorer program you would see that the problem Service Host did indeed have the Windows Update Service attached to it and when you stopped the Windows Update Service the CPU usage went back to normal.

From here you would now that disabling the automatic Windows Update Service would cause your computer to start working normally again and you could research a fix for the problem without the frustration of trying to user your computer when it was crippled. This simple free utility which answer the cryptic questions and allow you to save hours of labor moving to the step that many do and reinstalling Windows to try and fix a problem that when properly tracked down is a fairly easy fix.
