Have you ever reached this situation: "Your computer has encountered a problem that it could not handle and the disk usage is close to 100%, which is caused by the host of the service: Local System". This article explains how to deal with this bad situation. Before we begin to deal with the problem of heavy disk usage, we need to know what the extensible host and the service host are to help you better understand your problem.
What is the Service Host and Service Host Superfetch?
Svchost.exe is a generic host process name for services executed by dynamic link libraries. Microsoft has begun to modify much of the functionality of Windows by relying on the use of DLL files on internal Windows services (executed by EXE files). From a programming point of view, this makes the code reusable and easier to update. The problem is that you can not start a DLL file directly from Windows in the same way as an executable file. Instead, a shell loaded from an executable file is used to host these DLL services. And so the service host process (svchost.exe) is born.
Windows needs many services. If each service is running under a service host process, a service failure may cause Windows to crash completely. Instead, they are separated. The services are organized into logical groups that are all linked, and then a single service host instance is created to host each group.
