Windows 10 has been increasingly improved by Microsoft in terms of speed through many versions in many different ways – but the truth is that the speed is still slow, frozen when we do not set it up correctly. Of the many ways to optimize Windows 10, Service Host Superfetch is one of the features you need to know.
In this article, Ticswipe.com will explain what it is Superfetch? As well as the question “Should I disable Superfetch feature on Windows 10?”.
What is Service Host Superfetch?
Service Host Superfetch is a feature introduced and used first from Windows Vista. So what does Superfetch do? This feature helps to manage and improve the speed of the system continuously and efficiently. Until Windows 10 system, this feature still exists.
Superfetch runs in the background, automatically analyzing your computer’s RAM usage and knowing which applications you use frequently. After a while, it will mark the application as a “familiar application” and save the RAM application (preloading). The goal is that when you start executing the marked application, it will be faster because it is already stored in RAM.
Don’t worry that Superfetch is taking up all the RAM in your device to save “familiar applications” because it only stores unused RAM.
Should I disable Superfetch Windows 10?
On the positive side, the Superfetch feature is extremely useful if you use new generation computers with average configuration or higher. This feature helps the software that you use often can work “smoothly”.
But there are a few things you need to keep in mind when using Superfetch:
- Superfetch always runs in the background at the bottom of the system. It always uses the CPU and RAM of the machine.
- Superfetch does NOT save all frequently used applications to RAM, it only loads a portion of applications so you can start up faster.
- The speed of this feature will not matter when you use SSD for your computer. Because most SSDs today are very fast, and you don’t need to store these applications in RAM.
- Computer boot speed may be slow because Superfetch automatically saves a large amount of data from HDD to RAM. If your hard drive fails at 100% full disk within a few minutes every time you start your computer or restart your computer, Superfetch could be the culprit.
Is it ok to disable Superfetch Windows 10?
The answer would be No! Disabling this feature completely will not harm or affect your computer system. However, my advice is that if your PC is still working normally, you should leave it like that. If you encounter problems such as HDD 100% Fulldisk error, RAM usage too much, or reduced performance of other software, you should turn it off and see if it can help us.
