What is Superfetch?

The purpose of superfetch is to increase Windows performance by preloading apps. It detects all the apps you use frequently and preloads them when you start your Windows. superfetch keeps running in the background, checking and learning RAM usage patterns.

It marks the most used apps as a frequently used app and preloads them into your RAM to save processing time. So whenever you open your frequently used app, it will launch much faster.

You can check superfetch is running or not from Task Manager. Check all services and see if you can find “Service Host: Superfetch”. If it is there, then superfetch is running in the background.

The Problem?

Now you must be thinking, Superfetch is useful for Windows 10, so why disable it?

The issue is sometimes Superfetch is using so much CPU power. If you have a medium-range PC with avg specs, you don’t need to worry about it because it runs in the background silently, and you won’t even notice it. But if you are using a PC with low RAM and CPU, you can face some issues because Superfetch uses CPU and RAM in the background for learning RAM usage patterns.

Superfetch can make your boot time slower as it preloads the required data from your HDD to RAM. If you experience lag when start or restart your computer, Superfetch could be the reason for it.

You can disable Superfetch and make your boot time faster with SSD. SSDs are 10x faster than HDD, so your system doesn’t need to preload all apps. You can follow our guide to move Windows 10 from HDD to SSD.
