How to disable superfetch on windows vista

Service Host SuperFetch is responsible of high disk usage in windows 10 and sometimes it occupies 100% of disk which we need to sort out. So, what it is and how we can disable it to fix the full usage disk issue?

No doubt, Microsoft’s Windows 10 is an improved OS over previous versions in many ways, but for some users it doesn’t work well and they feel slow and sluggish when it isn’t configured properly.

To improve the system performance, you will get a lot of tool recommendations but there’s one lesser-known feature that you should know about in win 10 named: Superfetch.

In Windows 10 Service Host Superfetch causes disk usage, and later during the work it creates a lot of problem. So, in this article, you’ll learn what Superfetch is, how it works, and why it might be problematic.

In addition to that we will also look for the best ways to disable it if it’s causing issues. So, let see everything in detail below.

What Is Service Host Superfetch?

Superfetch is a feature that was introduced in the Windows Vista in 2006 and actually the successor to Prefetch which was introduced in the Windows XP. It has been said that SuperFetch improves the system performance but that’s bit unclear and doesn’t explain the whole story.

It shows up as “Service Host: SuperFetch” in the Windows Task Manager and works quietly in the background, and analysis the RAM usage patterns. Using that patterns, it knows very well that what kinds of apps you run most often.

So due to this awesome feature, SuperFetch marks many apps as “frequently used” app and preloads them into RAM ahead of time. And that’s the reason whenever you open the task manager and look in the performance tab you will see around 70% to 90% RAM is in use or it fully occupied.

By default, SuperFetch is designed to take up all your available RAM space with preloaded apps. But worry not, as it only deals with unused memory. So, in case… if any other new application needs more RAM, SuperFetch relinquishes the needed memory as necessary.

Is SuperFetch Really Necessary?

For the most part, SuperFetch is quite useful. If you have a modern PC/Laptop with average specs or better (8GB RAM, core i3/i5 or Ryzen 5), it most likely runs so smoothly that you won’t ever notice it. There’s a good chance SuperFetch is already running on your system right now and you didn’t even know.

But there are some “problems” that can arise with SuperFetch.

Since it is a service and always runs in the background, the SuperFetch service itself is always using some CPU and RAM.

It doesn’t eliminate the need to load apps into RAM. Instead, it relocates the loading to an earlier time. Whenever that loading thing happens, your system experiences some slowdown as if you were launching the app without SuperFetch.

System start up can also be sluggish because SuperFetch service is preloading a bunch of HDD data to RAM. If your HDD runs at 100% for a few minutes every time you start or restart your computer, SuperFetch could be the culprit.

However, the performance may be unnoticeable when Windows 10 is installed on an SSD. Since SSDs are so fast, you don’t really need preloading.

SuperFetch causes performance issues while gaming, particularly on systems that have 4GB of RAM or less and when this happens it constantly load and unload data and you fill some slowness while using your system.

Is it Safe to Disable SuperFetch?

Yes! There is no risk if you decide to turn off Service Host SuperFetch. Our recommendation is that if your system is running well, leave it on.

But if you facing issues with high HDD usage, high RAM & CPU usage, or degraded performance during RAM-heavy activities, then better to turn it off and see if it helps.

If it does, keep it off. Otherwise, turn it back on or go for a system upgrade – upgrade RAM (min 8GB), SSD (min 240GB).

How to Disable Superfetch on Windows 10

To reiterate, we don’t recommend disabling Superfetch except as a troubleshooting measure for the potential issues mentioned above. Most users should keep Superfetch enabled because it does help with overall performance. If you aren’t sure, try turning it off. If you don’t notice any improvements, turn it back on.

Using the Services App

Step 1: Launch the Services app. Open the Start Menu, search for services, then launch the Services app. Alternatively, open the Run prompt by pressing Windows key + R, then type services.msc and click OK.

Step 2: Disable the Superfetch service. Scroll down until you see Superfetch, right-click on it, and click Stop. Superfetch is now disabled.

Step 3: Prevent Superfetch from running automatically. Still in the Services app, right-click on Superfetch and select Properties. Under the General tab, look for Startup type and change it to Disabled. (Or Manual if you’d like the option to turn it on when you need it.)

Using the Registry Editor

The Services app is the preferred method for this, but if it doesn’t work for some reason, you can always edit the registry key directly. Before you do this, make sure you back up the registry in case something goes wrong (it’s more common than you think).

Step 1: Open the Registry Editor. Open the Start Menu, search for regedit, then select it from the results. Alternatively, open the Run prompt by pressing Windows key + R, then type regedit and click OK.

Step 2: Find the Superfetch key. Using the left sidebar, navigate to the following:

HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / Control / Session Manager / MemoryManagement / PrefetchParameters

Step 3: Disable Superfetch. In the right panel, you should see a key called EnableSuperfetch. Right-click on it and select Modify… to bring up the key editor. To disable Superfetch, change Value Data to 0 and click OK.

The SuperFetch service in Windows Vista preloads your system’s memory with the applications that you use most often. This makes launching of those applications much faster, but it might be an unwanted behavior for system tweakers or gamers.

There’s no hard evidence that enabling or disabling this service will increase performance in general, but if you open and close applications often you should definitely leave it alone. You will have to test your configuration to know for sure.

Note that I don’t recommend disabling this service, but we try to cover how to do everything on Vista.

Open up Services in Control Panel or by typing services.msc into the Start menu search or run boxes.

How to disable superfetch on windows vista

Double-click on Superfetch in the list to open up the properties, and then change the drop-down to “Disabled”. You can also click Stop to immediately turn it off.

SuperFetch Service in Windows 10?

The SuperFetch Service in Windows 10 is designed to catch frequently used program files and Pre-load them into RAM (Random Access Memory).

This allows frequently used programs and Apps your computer to use cached files from RAM, instead of fetching files from the Hard Disk.

Well some of you who launched to read this may have fairly an idea about super fetch in windows. Due to some reasons most of you would be looking out for how to enable or Disable Superfetch for Windows . If yes, then this is exclusively written to assist you. First of all for some of the non tech people let me introduce this term elaborately. Those who know please skip to next subheading don’t mind my lecture.

What is super fetch ?

Well superfetch technology is part of Window OS right from its vista version. It’s not a big deal to say that superfetch technology is one of the parts in windows memory manager.

Know what ? You should Enable Superfetch for Windows for particular reasons like these we gonna discuss .

Basically Superfetch has two aims firstly it reduce boot time and secondly to makes sure that the applications that you use the most loads fast and more efficiently. Superfetch adapts your usage patterns.

Let’s elaborate the first goal that is decreasing boot times. All through the Windows boot process, the same files need to be access at various different period of time. Superfetch also track record on which data along with files need to be accessed and when. It also stores all the track record data inside a trace file. During following boot, this information is used and helps to make the loading data/files faster and well-organized.

How to disable superfetch on windows vista

Superfetch performs more tasks to make the boot process more efficient. It also helps to increase the access speed by rearranging the files stored on the disk in order to occupy the contiguous storage locations during the boot process. Basically it performs this as a schedule task on all three day and the some of the specific file layout gets stored in the Windows/Prefetch/Layout.ini.

Let’s elaborate the second goal that is to make applications open or load faster. Superfetch simply does this by pre-loading the applications that are used mostly by you in your main memory, based on not only the usage patterns but also when one access or use it. For example, if you have the same daily routine of opening the chrome – gmail, SuperFetch will pre-load these into memory in the morning and help to load fast.

Superfetch for applications basically operates similarly as the boot variant does like, it traces what files are opened by an application during the first ten seconds that the application start up. It helps to load the proper data in memory at right times.

Superfetch & RAM

Superfetch really serves great to make you use fullest capacity of your RAM. The high you’re RAM the more you reap super fetch benefit. Superfetch helps in maintains and improves system performance overtime. Superfetch is actually a feature introduced back on the windows vista and it will constantly analyze & adapt the RAM usage pattern and apps you run most often.

If you have Windows vista then you will know that it takes a fair bit of memory to have it run smoothly. I personally think you need a minimum of 2gb of ram in Windows Vista, and if you do not, you may have to disable Superfetch.

What is Superfetch?

Superfetch is a service in Windows Vista that remembers and takes note of which applications you use often, and keeps them at hand, ready to open quickly. This is a fantastic feature if you have enough memory to store these programs on hand.

How does Superfetch work?

It monitors which applications you use the most and preloads these into your system memory so they’ll be ready when you need them. Superfetch is constantly working in the background; trying to anticipate what programs you will need the most. The only problem is, can we trust Superfetch to pick the right programs?

How does Superfetch choose which programs are important?

Can you tell Superfetch what applications to choose?

By altering your registry you can tell Superfetch to make its choice from just the boot files, applications only, both, or disable it altogether.

Superfetch is know as Service Host: Superfetch on windows task manager. The application quietly sits in the background and analyzes the application on your computer you use regularly. Superfetch then marks the application you use regularly as frequently used put then into the ram of your computer before you even start the application

For example, If you use Google chrome regularly then Superfetch will detect it and preload it into the ram. So the next time you open the app it will open instantly with any lag cause it’s already loaded in the ram.

Don’t be worried Superfetch is designed to use only the unused ram space on your Windows PC.

300 MB/s). Unless you use your computer differently EVERY single time you boot (and I mean a different antivirus, firewall, configuration, etc, which no one does), SuperFetch is a win, win, win situation. It puts the files in the memory NOW, letting the commonly used programs run faster right off the bat.

Welcome to the forum.

You are correct, but I was referring to the slight delay time it takes for everything to load into memory at startup and for the hard drive running more to load this as well. Using the sleep mode could solve this problem though. In most cases it is still faster with Superfetch on, but there are a some cases where it may not be so, like on servers.

Thank you for your comment, and I updated it to make it clearer on what I meant.

When you get 100 disk usage error on Windows, Superfetch service will be one of the factors that cause the high disk usage.

How to disable superfetch on windows vista

Superfetch is a service from Windows that can make you have better user experience of Windows. But it is not a good feature all the time. Now, you can read this MiniTool post to learn how to disable Superfetch if it slows down your computer performance.

Windows 10 has improved its performance in many respects and it is still doing the best to improve the users’ experience all the time. A lesser-known feature is Service Host: Superfetch.

Since it is not a very popular feature, many of you don’t know it. Due to this, in this post, we will mainly talk about Superfetch in Windows 10:

  • What is Superfetch?
  • Is Superfetch necessary all the time?
  • How to disable Superfetch in Windows 10?

What is Superfetch?

Superfetch is a feature that has been introduced since Windows Vista. It is described like this: maintains and improves system performance over time. But, you can’t understand all its functions from this simple introduction.

How can you see Superfetch on your computer? You can open Task Manager and go to More details > Processes. Then, you can scroll down the list to find Service Host: Superfetch.

How to disable superfetch on windows vista

Usually, it just works in the background to constantly analyze

RAM usage patterns and which apps you run most often. Over time, Windows Superfetch can mark these apps as frequently used and make Windows preload them into RAM ahead of time.

This means that when you want to open a frequently used app, it will be launched much faster than others because it has already preloaded in memory. Superfetch benefits this quick performance.

In theory, Superfetch takes up all the available RAM space with the preloaded apps. But, you should not worry about it since it only deals with unused memory. If you need more RAM to load an app that hasn’t been preloaded, it can relinquish some memory according to the needs.

Is Superfetch Necessary All the Time?

Superfetch is useful in most cases. If you are using a modern computer that is equipped with average specs or better, Superfetch is likely to run smoothly without influencing your user experience. You may even don’t know it is running in the background.

But, Superfetch may cause some “issues” as follows:

  • Superfetch is always running in the background. So, it will take up some CPU and RAM.
  • Superfetch is designed to load the frequently used app into RAM. This will slow down your computer in a sense.
  • Superfetch is always preloading some apps when you boot your computer. If your HDD always runs at 100% for a while when you start your computer, the Windows booting time will last longer.
  • If you are using an SSD on your computer, it is unnecessary to use Superfetch because an SSD can run very fast and you don’t need to preload your needed apps. If an SSD interests you, you can perform a computer data transfer from HDD to SSD.
  • Superfetch has been accused of the cause of performance issues while playing games. If you are playing games using a computer with 4GB of RAM or less, the performance may be slowed because the RAM-heavy games always request and free up memory so as to make Superfetch constantly load and unload data.

After knowing these issues, you will ask is it possible to disable Superfetch? Is it safe to disable Superfetch?

The answer is YES.

You can feel free to disable Superfetch without side effects. If your operating system is still running well, you can just leave it on. However, if you are always bothered by high HDD usage, high RAM usage, or some other performance issues, you can consider disabling Superfetch.
