How to Solve Sysmain High Disk Usage in Windows PC

A fast and efficient system is one of the most important things users need because it allows them to work more efficiently. But how will you feel if you have to wait about 5-10 seconds to open an application or program? This will certainly annoy you, so it’s best to keep an eye on your CPU usage and close the program with maximum CPU usage.

So in this article, we are going to talk about a service in Windows called Sysmain. Since this service has a high CPU load, here you will learn how to disable the high load of Sysmain on your hard drive.

What is SysMain

Sysmain is commonly known as SuperFetch. It already has a bad reputation under that name in Windows 7. It is a service that runs in the background. It constantly analyzes your computer’s behavior on your hard drive and thus determines which files and applications you use most often. Based on this information, SysMain effectively reorganizes your hard drive at the block level.

Why does Sysmain have a high hard disk utilization rate

When analyzing program usage patterns, SysMain sometimes exaggerates and overloads the hard disk. In some cases, the computer becomes virtually unusable within 10-15 minutes of starting because it is trying to load too many programs at once. Other reasons for high resource usage are launching an application with incorrect backend code, as Microsoft says, or trying to preload very large files (such as AAA game files).
