Is Superfetch Necessary for your Device?

Not really. If you have Windows 10, know that it has been installed on an SSD. Since SSDs are fairly fast, you scarcely need any preloading.

Is Superfetch Good for Gaming?

It is found to be not very user friendly when it comes to gaming, but it works really well with the business applications.

How does it Work?

It works by preloading the installed memory of your device, with the most frequently used programs. Usually, the data is reloaded by the hard drive, taking a long time to process. With the help of Superfetch, you can reduce this time consumption.

Superfetch tracks the files which need to be loaded. It also tracks the time on which the respective boot process is depending. After tracking, Superfetch reduces the boot time.

There is a Prefetch directory within the Windows’ folder. In order to examine the steps, you can navigate to the ‘Layout.ini.’

Based on the usage pattern of your device, Superfetch preloads the most frequently used applications. The reason behind this is to ensure that the apps are being launched quickly.

SYSTEM LAYOUT:The 'Layout.ini' file contains details of the files accessed during boot time and the order in which they are used.

The preloaded applications which you would use in the morning might be certainly different from the one which you would use in the evening. This happens, because Superfetch also examines the differences which occur at different hours of the day.

Superfetch makes sure that when a certain application is launched, it is available in the random access memory.

What is the Misconception about Superfetch?

Usually, when a user of Windows’ 7 or alike opens the task manager of the device, they see a ratio between the cached, and the available space. This ratio often shows the cached data in a higher ratio to the free space. This results in the user perceiving that the Superfetch system process or alike has taken up all the space on the device, and thus, they are now left with a very little space to launch the desired applications.

But, they do not know that Superfetch consumes the least possible memory on their device. The cache which has been occupied by Superfetch or any other basic catching mechanism runs on a lower priority.

What is the Truth about Superfetch?

Regardless of the myths, the reality cannot be changed. Superfetch is one of the intelligent mechanisms which makes your computing a smoother experience.

It is now in our nature to get annoyed by the slightest of an inconvenience. We often ignore researching on a certain matter to educate ourselves.

What is the Relation between RAM and Superfetch?

It is said that the higher RAM you would have, the more benefits Superfetch would give you.

According to Tom’s Hardware research, a device which had 2GB of RAM, noticed a positive change by using this system process.
