Although some people may disagree with me on this as they can not feel the same at times, Windows 10 is definitely a nice upgrade over previous versions in a lot of ways.
Then again, the windows 10 might sometimes feel pretty laggy and slow if you haven't configured it properly.
Among the many ways to increase the performance ability of your Windows 10, there is one feature which is lesser known and that is SuperFetch. People must actually know what this is and what is its purpose.
In this particular article, you will get to know everything that is required for you to know about what SuperFetch is, how it works, why it may be problematic, and how to disable it in case it is causing problems.
How SuperFetch Speeds Up Your PC
If you go through the formal representation of the SuperFetch service, then you will see that it quotes that it “maintains and improves system performance over time."
But that is not enough and proper to describe the actual functionality and uses of SuperFetch.
Back when Windows Vista was released, this feature was introduced in the operating system.
It remains silently in the backdrop, regularly examining RAM usage patterns and seeing what sorts of apps you run and use the most.
Over a period of time, SuperFetch takes a note of these particular apps and marks them as"Frequently used". Along with this, it even preloads these apps into the RAM before time.
The concept is very simple. It makes sure that when you finally decide to run those apps, it will launch themselves faster than normal. This happens as those apps are preloaded in the memory of your system.
This enables you to have an even more smooth experience while using your most frequently used app.
By default, SuperFetch is meant to use up all the unused space in the RAM with preloaded apps. But there is nothing to be worried, as it uses only space which is free.
The moment your system is in a requirement of memory, maybe to launch some app which was not preloaded previously, SuperFetch releases the RAM space in order to enable the user to run this new app.
At this point in time, you need to understand that SuperFetch is not the same thing as Prefetch. Basically, Prefetch is the preloading memory manager that was launched back into Windows XP during its official release.
As a matter of fact, SuperFetch is the successor to Prefetch. The difference is that Prefetch did not examine usage patterns over a period of time and accordingly adjust its preloading parameters.
Is SuperFetch Really Necessary?
The big question that a user often asks is that, whether really SuperFetch is necessary or not. For starters let me tell you, SuperFetch is indeed useful.
If a user is using the Windows 10 operating system on a modern computer with a specification which is mediocre, then SuperFetch is likely to run in the background so smoothly that you won't even notice.
In fact, there is a pretty nice possibility that SuperFetch is currently running on your system in the background. Well, did you even know that?
then there are some particular issues which happen or occur with SuperFetch:
1. Since SuperFetch is continuously working in the backdrop, as a result of this, the SuperFetch service itself is constantly using some CPU and RAM.
2. SuperFetch doesn’t reduce the requirement to load apps into RAM but only changes the loading to an earlier time. Whenever that loading occurs, your machine is bound to encounter the same slowdown same as it would experience if you would've launched the app without SuperFetch.
3. System startup can be slow only because SuperFetch is preloading a collection of data from your HDD to RAM. If your HDD is running at 100% for an even some time, at every instance you boot or reboot your machine, SuperFetch could be the offender.
4. The performance advantages of SuperFetch might not be even noticeable if the Windows 10 operating system is installed on an SSD. This happens because SSDs are very fast. You don’t even really need preloading.
SuperFetch has also been recognized to create performance problems while gaming, especially on machines that have 4GB of RAM or less.
It’s unclear why this occurs because it doesn’t happen for everybody, but we assume it has to do with RAM-heavy games that continually demand and free up memory, which may make SuperFetch to constantly load and unload data.
Another question which often asked by the user is, Is it safe to disable SuperFetch?
Yes Obviously. There is absolutely no risk that you may encounter some side-effects if you turn it off. Our suggestion will be to first examine how your system is performing.
If it is performing much to your expectations, then there is simply no need to turn it off. If you have issues with high HDD usage, high RAM usage, or degraded performance during RAM-heavy activities, then try turning it off and see if it helps.
If it does work for your system, keep it off. Otherwise, turn it back on.
How to Disable SuperFetch on Windows 10
Just repeating to make this clear, we don’t recommend disabling SuperFetch unless as a troubleshooting step for the possible problems discussed above in the article.
Majority of the users we feel should keep the SuperFetch enabled as it can enhance the performance ability of the system overall.
In case you are not sure about this, trying to turn it off and examine if that is making your system running in a smoother way or not.
If it doesn't enhance the performance, turn it on again.
Here are the ways which can help you to enable the SuperFetch:
1. Using the Services App-
Step 1: You firstly need to open the Services app. Open the Start Menu, search for services in order to start the Services app.
Alternatively, open the Run prompt by pressing Windows key along with the R key at the same time, then type services.msc in the run dialog which follows and simply click OK.
Step 2: Disable the SuperFetch service. Scroll down until you notice Superfetch option. Right-click on that, and choose the Stop option.
SuperFetch will be disabled from now on.
Step 3: Up next your target should be to block SuperFetch from running automatically. Stay in the Services app and right-click on Superfetch.
Then select Properties. Under the General tab, see for Startup type and change it to Disabled. You can also choose Manual if you would like the choice to turn it on when you feel the need to do it.
2. Using the Registry Editor
Generally, the Services app is the method which is chosen in order to uninstall SuperFetch.
But there are times when it might not work because of some or other reason. In this case, you can always edit the registry key directly.
Before you go on to do this, be assured you back-up the registry in case something goes wrong. It is actually very common that something might happen. There have been many users in the past who have reported that.
Step 1: Open the Registry Editor. Open the Start Menu, search for regedit, then select it from the results which follow.
Alternatively, open the Run prompt by pressing Windows key along with the R key, then type regedit and click OK.
Step 2: Find the SuperFetch key. Using the left sidebar, Go to the following: HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / Control / Session Manager / MemoryManagement / PrefetchParameters:
Step 3: Now you can disable SuperFetch. In the right panel, you will notice a key named EnableSuperfetch. Right-click on it and choose Modify… to lead up to the key editor. In order to disable SuperFetch, just change the Value Data to 0 and click on the OK option.
Though SuperFetch is a very lesser known feature, it holds some relevance in the performance of your system.
