Service Host: Local System (Network Restricted) Is Using Too Much Of Your CPU Resources
Some time ago Microsoft started changing the Windows functionality from depending on internal Windows services (which ran from .exe files) to using .dll files. You can’t launch a .dll file directly from Windows the same way you can launch an executable (.exe) file. Instead, a shell that is loaded from a executable file is used to host these .dll services. And that is how the Service Host process (svchost.exe) was invented.

Service Host: Local System is a collection of system processes which operates automatically through system. It includes processes like Windows Auto Update and many others which takes up huge memory, disk, RAM etc. You may have noticed that almost all your available network is taken by these processes. This problem is frequent in Windows 8 and 10 operating systems. So, Service Host(svchost.exe) is a generic service hosting container, any number of required system services can be running in it. Running services are arranged into groups that are all somehow related, and then a single Service Host instance is created to host each group.

If you’re using Windows 8 or 10, processes are shown on the Processes tab in the Task Manager window by their full names. If a process serves as a host for multiple services, you can see all of these services by simply expanding the process group. By doing so you can very easily identify which services belong to each of the Service Host process.
Problems with high CPU (Central Processing Unit) usage can impact your PC performance remarkably. If you are running Windows 10 and you find that Service Host: Local System (Network Restricted) is taking much of your CPU, Disk or Memory usage then you are at the right place. In this article we are going to show you several ways how you can fix this problem. Read the guide below and find the solution which works best for you.
