What is service host superfetch – How to Fix High Disk Usage

What is Service Host Superfetch?

Superfetch was first seen in Windows Vista , a fairly old operating system that is no longer supported by Microsoft . In terms of features, Superfetch helps to manage the system memory in the computer’s operating system to improve speed efficiency.

Currently, the Superfetch feature, available in Windows Vista, Windows 7, Windows 8, and Windows 10, is still available.

Can be understood simply as Superfetch as a computer memory manager in Windows

However, according to many on the forums, Superfetch is one of the reasons that can affect the performance of some applications. So disabling the Superfetch service has a lot to do with the computer, or in other words, is Superfetch really necessary? We will move on to the next one.

Does my computer need Superfetch?

To say that Superfetch is useless is completely wrong, because in some cases Superfetch is very useful. For example, if you are using a new generation computer with a medium or higher configuration, this service will help make the software you use smoother. However, if we dig deeper, we can see that Superfetch causes some of the following problems: Superfetch always runs in the background on Windows system. This means that it uses the processor and RAM of the computer => Wastes resources.

Superfetch doesn’t store all the apps you use in RAM, just a portion so you can load faster.At boot, Superfetch preloads the dataset from the hard drive into RAM. If your computer is frequently experiencing a 100% disk full error when you boot your computer, Superfetch may be the cause.The speed Superfetch provides is negligible if your computer is equipped with an SSD hard drive. Since using an SSD will help the computer start the computer, applications and processing tasks are smoother.

In short, to answer the question “Do you need Superfetch?” then I will answer no. And disabling superfetch has nothing to do with the computer or not. In the next part, we will learn how to disable superfetch in the Windows operating system. Also, if your computer is too slow, I recommend that you upgrade to an SSD because it is the fastest and easiest way to speed up your computer. The current SSD price is also relatively cheap compared to what it was a few years ago. There are about 500k to buy a good SSD. If you are interested, you can consult Ben Computer. Consult your SSD now.
