What is Superfetch Windows 10? 

The most simple answer of What is Superfetch Windows 10 is, the Service host superfetch is just a way for Windows to provide users with convenience.

Now I know that it doesn’t provide any clues for Windows users as to what it is, which is why in this article we will dive into what is superfetch in Windows 10 is (and another example). 

Many of you have heard that disabling superfetch will make your computer as fast as a supercomputer (easy and humorous), but does it? 

In this article, I will break some myths about superfetch and tell you what superfetch is

Superfetch is one of the intelligent functions of the Windows operating system, which is often misunderstood by most people. So let’s take a look at what superfetch is and what crazy myths about superfetch are completely untrue. 

Superfetch is a Windows feature. After Windows Vista, superfetch entered Windows 7, then Windows 8, etc… Now, most of you are not familiar with Windows Vista, so let me give you a brief definition.

What is Windows Vista?

For those who do not know Vista, 

Windows Vista is a major release of the Windows NT operating system developed by Microsoft. Development was completed on November 8, 2006, and over the following three months, it was released in stages to computer hardware and software manufacturers, business customers and retail channels.

On January 30, 2007, it was released internationally and was made available for purchase and download from the Windows Marketplace; it is the first release of Windows to be made available through a digital distribution platform.

The release of Windows Vista came more than five years after the introduction of its predecessor, Windows XP, the longest time span between successive releases of Microsoft Windows desktop operating systems.

Where can I find superfetch in my task manager? 

You can always see superfetch (sometimes called service host superfetch) in the administrator task running in the background. It is called “Service Host: Superfetch“. 

What is Superfetch in Windows 10?

It is an A.I. superfetch analysis of RAM memory usage patterns, which applications or software you use most often. Therefore, it will mark these applications as “frequently used” and preload them into RAM before your next run so that you can access them faster than usual. Isn’t it cool? 

What is the role of superfetch in Windows 10?

It mainly reduces two things: the first is the startup time, and the second is the application/software loading time. 

What is the boot time? 

The time it takes for a device to be ready to operate after the power has been turned on.

So how does superfetch reduce startup time and application loading time?

You have seen many times that when you turn on your computer, it takes a few seconds to load. 

Do you know why it takes so long?

The problem is that currently superfetch is loading some of its drivers and other small software in the background (usually those applications that are marked as launching applications). And applications, such as Internet Download Manager, etc.

Superfetch reduces boot time by tracking which files need to be loaded and when they are loaded during the boot process. And superfetch stores this information in a trace file for future use, so the next time you turn on the PC, this information will be used to speed up the boot time. 

Two things, which applications do you use and what time of day you use them, and then just like in the startup time scenario, it will preload these applications into your main memory. For example, if you open any games at 10:00 every night, superfetch will preload them into memory so that you can access it faster. 

Techgenix.com has a very simple explanation of this, please see: 

For the Windows operating system to load, or for any application to load, we need data files, which need to be accessed in a specific order. Now, the best-case scenario for quick loading is, when:

The files are available in fast access memory, that’s RAM.
The files are placed in the sequence they’ll be needed in.

SuperFetch analyzes the booting, and the application loading, and prepares a trace document with all this information. This trace document, then, helps SuperFetch prepare beforehand, so that it can arrange the files in a manner that enables the fastest loading.

Disadvantage of Superfetch Windows 10

But there are some disadvantages to using superfetch. It takes up a lot of memory to make caches. But still, superfetch manages the use of cached data in RAM to ensure quick access to your favorite applications/software.

low ram issues

If you think you should delete it, it’s too much cache for your PC, believe me, I don’t recommend deleting it because it will fill up again after a while (while opening other applications).

The goal of caching, in general, is to increase performance by making resources available before they are needed; in this case, loading data into RAM that the kernel thinks may be useful in the future (which is not always correct).

So even if there is a way to clear it, there is really no need to, and it would just fill up again.

Also, note that RAM is volatile, so the cache isn’t kept when the system is not powered.

Superfetch causes 100% disk usage

Although it is a great feature in the Windows operating system, it also has some disadvantages. Namely, 100% superfetch disk usage problems. Windows has experienced 100% disk usage by superfetch in the task manager,

But why does superfetch show 100% disk usage?

You might be wondering if Superfetch is so easy to use, so why does the annoying process in Windows 10 require high disk usage? Simply put, the memory manager process itself requires a certain amount of memory to run smoothly.

In addition, it also tends to run in the background, but this is not the only reason. Sometimes it messes up on its own, not knowing when to stop or preload what process.

In startups, running all the processes that could be run in the future will get worse. Many users repeatedly report that Superfetch hinders them while playing games and reduces the frame rate.

Many people also say that the Superfetch process can cause unexpected memory spikes and sometimes even freeze the system.

What is the difference between prefetch and superfetch in Windows 10?

Superfetch and Prefetch are different, but they are still the same. 

What do I mean? There is only one difference between prefetching and superfetching.

SuperFetch is a performance enhancement introduced in Microsoft Windows Vista to reduce the time necessary to launch applications.

SuperFetch works with the memory manager service in Windows to analyze memory usage patterns over time to determine the optimal memory content for a given user for a date or time of day.

This differs from the Prefetch technique used in Microsoft Windows XP, which preloads data into memory without analyzing usage patterns.

Simply put: Superfetch preloads data into memory by analyzing user usage patterns (such as when the application is opened), while prefetch does not. 

This is the difference between prefetch and superfetch.

Prefetch was first introduced in Windows XP, so it can be said that Superfetch is an advanced version of Prefetch. 

Here is a brief description of prefetching.

Should I disable Superfetch in Windows?

Is it safe to disable Superfetch and should I do it? Well, when you disable any Windows feature, you may encounter hundreds of major errors, but in superfetch, this is not the case.

However, it will increase your startup time and the response speed will be slower while opening programs and other minor issues. You should not disable it.

However, you can disable it in certain situations.

Why should I disable superfetch?

There are several reasons. Many Windows users face high disk usage problems due to superfetch.

Since Superfetch always runs in the background, it has been using some CPU and RAM.

Many Windows users report that superfetch reduces their gaming experience.

My suggestion is to disable it once, please check your computer performance and if your computer runs smoothly, then it’s okay. Otherwise, turn the superfetch back ON

How to disable superfetch Using Command Prompt?

Search for the command prompt in Windows, right-click and run as administrator, then type the following command and press Enter.

net.exe stop superfetch
