What is Service Host Superfetch?
Service Host superfetch is a perfect example of features becoming a headache. After windows vista Windows started to come with many system processes to manage system files and One of them is service host Superfetch. Microsoft wanted To make this process as a memory manager, who works By analyzing usages and patterns for optimizing memory.
One of The most common problems This process gives is High disk usages (memory leaks) which make your pc/Laptop slower.

Service Host SuperFetch is a Windows process that was Microsoft introduced to make faster and improve hard drive performance like Cortana. But, the real problem comes when most of the user’s face and complaint about it causing slowdown with an SSD. So let’s go a little bit deeper into this matter and know about this in a particular way.
SuperFetch is a memory manager that examines usage patterns over time to optimize memory content. It was initially introduced in Windows Vista as a successor to PreFetch, which was found in Windows XP.
It helps third-party apps and critical Windows components to administer everyday tasks quickly. Superfetch stores and reads data for regularly used apps directly from RAM instead of storing to the hard drive to achieve good speed.
The main objective of the feature is to speed up application load times for those running hard drives—especially older ones.
If you are using an SSD, you don’t need SuperFetch to pre-load an application because programs run remarkably fast on SSD in comparison to HDD.
So, you won’t see any noticeable change in SSD-driven applications whereas it brings proper improvement in the performance of hard-drive.
What makes it report 100% system high disk usage?

Probably, That’s not the only reason.
Sometimes, it can mess up on its own, not knowing when to stop or which process to pre-load. On bootups, it runs all the operations at one time, which could have been executed later on, which makes the things even worse.
Service Host SuperFetch might occasionally go wrong and cause more problems than the service it offers. Since SuperFetch is always running in the background, it does make use of some system resources like CPU and RAM.
If you’re running a heavily optimized system or one with particularly weak hardware, could cause slowdowns which most of us hate.
Most of the windows users also complaint on how Superfetch comes in their way while playing games, taking high CPU usage, and cause frame rate drops.
It’s possible that because of the road games will pick up and drop RAM as and when it’s needed, that SuperFetch is getting in the way and causing gameplay stumbles while everything shuffles around in memory.
