Service Host Superfetch – All You Need To Know [2019]

So, I was just sitting here on my laptop, scrolling through the posts, and guess what, my browser crashed. I investigated more by checking what’s going on with the help of the Task Manager. All I found was this one thing, a thing so huge that caused my whole system to freeze. It was a simple process called Service Host Superfetch. I dug deep into the issue to find out What is Service Host Superfetch, and how to stop it from damaging my system.

The thing I found was this. Service host Superfetch is a Windows service that allows various system and application processes to store and read data directly onto the RAM, instead of the hard disk drives. Superfetch is based on the concept of caching. It stores frequently used data on the primary memory (RAM) and uses it from there. This helps save time while executing various tasks and programs. But, when it breaks, it caused serious damage to a system.

Are you facing the same problem while using your system, or is it just for increasing knowledge in your geeky brain? Whatever the reason be, here in this article I will discuss exactly What is Service Host Superfetch, What it does to your system, and finally we will take off by demonstrating some workable methods to Stop Service Host Superfetch from wrecking your machine.

Let us start by learning what Service Host really means. Ready? Let’s go.

What Is A Service Host?

Service Host is a service manager in the Windows operating system that has the function to load services from DLL files. DLL files are special files that cannot be executed like other programs. They demand a special purpose shell for their execution. What Service Host usually does is that it loads services from DLL files and creates separate instances for all of them. This enhances continuity as any problem in one instance does not affect the service running on another.

There is a program that goes by the same name – svchost.exe. The job of svchost.exe is to minimize memory usage of the system by allowing a resource to be used by different services at the same time. This reduces the memory consumption. Because in Windows, the creation and deletion of processes is a memory consuming process. And, creating an additional process for different services can be resource hungry.

The services are managed by the Service Host process and the allocation of a resource to these various services are managed by svchost.exe. This is how we explain the relation between Service Host and svchost.exe. Note that these two are separate terms and must not be confused with each other.

What is Service Host Superfetch?

Windows Superfetch is the successor of a technology called PreFetch. Superfetch is a technology that is implemented into the Windows operating systems. This technology allows systems to manage their memory efficiently. Superfetch is responsible for the quick completion of various user and system processes. Superfetch technology is based on the concept of Caching. The system reads and writes the data produced by a process on the main memory. Main memory is normally faster than any secondary storage device like a hard disk. This makes the task finish quickly and efficiently.

Generally, Superfetch learns what you are using the most on your system. It collects the data that is used frequently by processes and stores it on the main memory. Whenever the system is shut down, all the loaded data on the main memory washes away. New cache blocks for the data are generated again whenever the computer boots up. However, the Superfetch remembers what you use the most even after a successful reboot.

If you have an SSD (Solid State Disk) on your computer system, you will not be experiencing much effect caused by Superfetch. This is because Superfetch is programmed this way. It automatically disables itself whenever it discovers an SSD in the system. In short, only hard disk users can see a gradual positive effect on their system’s performance.

When Does Service Host SuperFetch Go Wrong?

Service Host Superfetch has the duty to make efficient use of Windows memory. But, sometimes it destroys the one thing that it swore to defend. As the Service Host Superfetch demands memory to execute its tasks, it sometimes breaks and takes up more memory than needed. The process does not know when to stop a service and when to load one. This loading consumes memory and takes up most of the memory storage in a RAM.

How Does Service Host SuperFetch Affect the System?

The process named Service Host Superfetch takes up 100% of the main memory and cause multiple issues in a computer system. Some reported problems are listed below in details.

  1. Frame Drops in Games – Many gamers have reported that Service Host Superfetch takes up most of their primary memory and affects their gameplay. The most common issue in games is the dropping of frames.
  2. Freezing Of System – Service Host Superfetch sometimes freezes the whole system due to lack of memory available for other programs.
  3. Affects Boot-Time –  This process has a lot of impact on boot-time. It sometimes gets in the working of preloaders that are responsible for the successful boot of a computer system.

Should I Disable Service Host Superfetch?

There are around 100s of processes that cause issues when a user disables them. But, good for you, Service Host Superfetch is not one of them. It is merely a memory management process that is programmed specially for loading and stopping memory allocated to the services. To sum up, you can disable the process without any second thoughts. Disabling the process has a very slight impact on a system’s performance.

What If I Disable Service Host SuperFetch?

There are a few performance issues that you may face after disabling Service host Superfetch from your machine. However, they do not have a major impact on your system in general. We have discussed them in details below.

  1. Increase in Boot-Time – After you have disabled the process, you may experience a slight increase in the boot time. This is because of the services that are started during boot time. Service Host used to manage the memory of those services and now that you have disabled it, it does not.
  2. Increase in Response Time – After disabling it, Windows systems do not have any other dedicated process for managing memory efficiently. So, it causes improper management which can lead to slower response time while operating the programs.
  3. Some other unnoticeable bugs

So, now you know the consequences of disabling the Service Host SuperFetch process. I personally do not recommend disabling the process if you do not face any problem due to it. But, if you are facing the 100% disk usage error due to the process, you can go ahead and disable it without any concerns.
