Many Windows users have suffered from the problem where up to 95% of their CPU and Disk have been used by a process called Service Host: Local System and Service Host: Network Service. These two processes often cause 99% to 100% of Disk and CPU resources.

Many readers have asked us about Service Host: Local System and what it does. Well, it’s one of the vital system processes for a reason. So, in this article, we will cover everything about Service Host: Local System.

What is Service Host: Local System?

Service Host: A local system is vital and operates automatically. Service Host Local System’s process includes Windows Auto Updates, Background Task Management, IP Configuration, and many more. During the Windows Auto Update, the Service Host: Local System can also consume your internet data.

However, the Service Host: Local System runs silently and doesn’t interrupt our ongoing work. Still, if your computer runs on less than 2GB of RAM or has a low-end processor, it can interrupt your entire Windows experience. This process also causes overheating issues, harming the battery life of a laptop.

According to Windows Users, the Service Host: Local System’s high CPU and Disk usage is caused by the Windows System Service known as Superfetch. But it’s still a critical process that deals with lots of stuff. Usually, the Service Host: Local System troubles users after startup when it tries to do different tasks simultaneously.

Superfetch is a technology that allows the operating system to manage random memory. Thanks to Superfetch, our apps open quickly. Superfetch analyzes the RAM usage patterns to learn what type of apps you run most often. Over time, Superfetch marks these apps, preloading them into the RAM, which causes the app to start quickly.

However, we hardly need this feature, and the SuperFetch service causes high CPU and RAM usage. Thus, the SuperFetch service is the root cause of High CPU usage on Windows. To fix the Local Host: System Service’s high CPU usage, we need to disable Superfetch.
