SuperFetch is a kind of service that is an application for preloading different types of programs. In other words, analyze your system for actively used utilities, after launch, add them to your computer’s memory. This is done to maximize the loading speed of applications for subsequent work with them.
All SuperFetch jobs happen outside of user visibility. Remembering the programs that the user uses permanently, before starting the application, he downloads his data in RAM, if his volumes allow it. Thus, when you run the program, the calculations will not start from the beginning, but from the platform created by the service.
Based on this, we can conclude that the visibility of the loaded tasks and their actual number may differ. You may have noticed that an application that you use regularly starts up much faster than others with a similar load capacity. This consequence is a derivative of SuperFetch.
When this Service started
Service host superFetch was released in Windows Vista, after which the service was included in future versions. As technology advances, this solution becomes less and less relevant, so you can even turn it off.
Sometimes, when this feature is disabled or even enabled, system errors occur, but this is rather an individual feature of some changes. Accordingly, you should change the status of the service in this case.
In turn, this approach is useful, but also requires additional RAM for possibly unnecessary programs at this time. This way, you can decide whether or not SuperFetch is worth the resources spent. In general, it is recommended to stop the service for low-power computers whose resources do not support the operation of additional processes, although useful.
If you are using an SSD, you can also disable this feature as it will not bring much benefit. You can also disable the PreFetch service; these are included and perform similar tasks. At the moment, in modern computers, SuperFetch has lost its relevance due to its high power, because there is no need to download additional information in advance, the launch takes place quite quickly.
There are several ways to disable the SuperFetch service; similarly, you can enable it, namely: using the standard “Services” menu and the registry editor.
The first option is preferable, because the function is provided by the manufacturer and does not require solutions.

The following method is not preferred to use but helps some users in cases of problems in the services.msc file.
Disable the SuperFetch Service in the Registry Editor
Press the Win + R key combination;
Enter the word regedit and press Enter;
You should follow the following path HKEY_LOCAL_MACHINE # SYSTEM # CurrentControlSet # Control # Session Manager # Management Memory # PrefetchParameters;
Find the Enable Superfetch parameter, if it is not there, create it in DWORD format with the appropriate name;
You must set the value of this variable to 0 to disable SuperFetch, number 3 is suitable for activation;
To disable the PreFetch service in the same window, you should select the EnablePrefetcher variable and set it to 0.
By performing such simple steps, you can erase some of your memory, but in the case of computers with medium capacities, you will most likely notice a slowdown in application loading for a few seconds, which is also not critical. In other cases, when the computer is low-power and cannot handle an additional service or vice versa, a powerful machine, then you will only benefit from disabling the function.
