Why svchost.exe (netsvcs) high CPU usage problem occurs?

Have you ever wondered what svchost.exe is and why it is running on your Windows computer?

If you open Task Manager and look at the Processes tab, you may notice there is more than one svchost.exe running on your Windows PC, and you can’t just stop it by killing it within Task Manager.

So, what is it and why is it running on your computer? Is Svchost high CPU usage really a technical issue?

According to Microsoft, svchost.exe is a generic host process name for services, which run from dynamic-link libraries. Microsoft has moved all functions of Windows services into dynamic-link library files (the .dll file).

However, you can’t execute a .dll file directly from Windows. It must be loaded from an executable (.exe) application. That’s the reason why svchost.exe was born.

Why is More Than One svchost.exe Running?

You might know Windows has a lot of services, and if you have ever looked at any of them, many of them are required when booting the Windows operating system (OS).

Therefore, if Windows only uses one svchost.exe instance to load all services, then failure might bring down the whole Windows system. In this case, Microsoft organized services into logical groups, and each svchost.exe will be created for each group.
