Superfetch service: Windows 7 Disable?

What is Superfetch? 

The Superfetch service in Microsoft family operating systems was used even on the old Windows 7 and now in Windows 10 also. Then it made sense because it helped to speed up the computer somewhat.

How? And due to the fact that it collects statistics on the most used programs, utilities, applications, and, based on this data, preloads the necessary modules and elements in the computer’s RAM. In some cases, the service may even perform entire operations, for example, start defragmenting hard disk partitions or other background processes. But now, with the advent of new technology for the manufacture of standard SSD hard drives, the need for such a service has disappeared.

It a service that constantly runs in the background and learns which applications are used most often. Over time, it marks these applications as “frequently used” and preloads them into RAM.

If you have a modern computer with at least average specifications, the SuperFetch service will work well and will not be a problem.

Superfetch service: Windows 7 Disable?

In most cases, SuperFetch really benefits. If you have a modern computer with at least average specifications, the service host sysmain also called superfetch service will work well and will not be a problem.

However, it can cause some problems:

Because SuperFetch always runs in the background, the service itself always uses processor and RAM resources.

SuperFetch does not completely eliminate the need to load applications into RAM but simplifies the speed of the process. Whenever a startup occurs, your system will experience the same slowdown as if you were running the application without SuperFetch.

Starting the system may slow down because SuperFetch preloads a large amount of data from the hard disk to RAM. If every time you turn on or restart your computer, your hard drive runs at 100% charge for a few minutes, then SuperFetch may be to blame.

The effect of using SuperFetch may not be noticed if Windows 10 is installed on an SSD. Because the SSD is very fast, no preload is required.

SuperFetch can cause gaming problems if your system has 4 gigabytes of memory or less. This issue is relevant for games that use a large amount of RAM, which constantly requires and releases memory. This behavior can cause SuperFetch to constantly load and unload data.

In this regard, the question arose – is it necessary to disable SuperFetch or not? The answer is unequivocal: if you have installed a modern solid-state drive, you simply need to disable Superfetch But when the old HDD is still in use, then you can leave it.

How do I disable SuperFetch?

This can be done in two ways.
The easiest and fastest is through the Service console. Press the Win + R key combination so that the “Run” window appears.

Enter the services.msc command and click the “OK” button. After that, the “Services” system console should appear in which you need to find the SuperFetch line and double-click it with the left mouse button.

In the properties window that appears, find the “Startup type” field and put the value “Off” there. Press the OK button and restart the computer.

The second way is for advanced users. It allows you to stop the service and, if you want to leave it, set it up correctly. What is certain is that initially the Superfetch service is used both to speed up the system startup and to load applications faster. By setting the correct mode, you can force it to optimize either the system or the application or both. Call and open the section: HKEY_LOCAL_MACHINE \\\ SYSTEM \\\ CurrentControlSet \\\ Control \\\ SessionManager \\\ Management Memory \\\ PrefetchParameter. It must contain the “EnableSuperfetch” key:

We double-click it to edit the value.

Here, in the “Value” field, you must specify one of the options for the Superfetch service as a number:

0 – completely disabled 1 – only application launch acceleration works 2 – only launch acceleration works 3 – both system launch and application launch acceleration is active

By default, the last option is used. To disable the Windows accelerator service, set the value to “0”, click the “OK” button, and restart your computer.
