Windows 11 SuperFetch: what is it, how does it work and how to disable it?

We are going to explain what the SuperFetch function is and what it is used for, which you can find in Windows 11. It is a system that is always on by default. What it does is to use the RAM memory that you are not using with your applications to preload other programs in case you are going to use them. We are going to try to give you a clear explanation about this mode so that you understand the benefits it has. Remember that in the end, it is only using RAM memory that you are not using at the moment. But just in case, we will also explain at the end the method to disable it. However, it is not advisable to do so.

What is SuperFetch

SuperFetch is not a new mode. In fact, it’s a feature that has been in Microsoft’s operating system since Windows Vista. What it does is try to improve your experience by preloading applications that you use often. This way, when you open them, they take less time to load. For that, it first analyzes your RAM usage patterns in the background. And with this, Windows is able to learn which applications and programs you use the most in your daily life.

Knowing this, SuperFetch uses the RAM memory that is in disuse to preload the applications that you use the most but have not yet opened in RAM memory. It is as if it were opening them in advance. So when you decide to open them, they are already loaded and everything goes much faster.

All this is done only with the RAM memory that you are not using. The applications you open on your computer are loaded into RAM. However, you are not always going to be using all the memory installed on your PC. Consequently, Windows tries to make better use of the excess. With this, as soon as your operating system needs to use more RAM to load other applications, the tool dispenses with the necessary memory. In this way, it does not hinder the correct functioning of the system.

Because of this, SuperFetch is a feature that you will never notice and that will not bother you in your day-to-day life. It will generally never cause your computer to slow down. If it does, it will only last for a few seconds. In return, your PC’s performance will improve overall.

What SuperFetch is for

SuperFetch is used to make the applications you use the most load faster. We all get annoyed that if we use an application a lot, when we turn on the computer and open this application, it takes too many seconds to load. This is why the Windows function automatically preloads the most used applications in RAM. As a result, when you open them, they load much faster.

It’s not something that will bother you. In fact, this is not the same as when applications like Chrome consume too much RAM and everything slows down. And that’s because SuperFetch takes care of monitoring your RAM consumption. Therefore, when you are going to need that you had left over and is using, it can release it so you do not notice that it was being used behind.

The only downside is that this feature will cause your CPU and RAM to be constantly working. If your computer is very underpowered or has very little RAM, disabling it might speed up its performance. But only in specific cases. It can also cause some occasional problems when playing games if your computer has less than 4 GB of RAM. On the other hand, it can also make the CPU work a little too hard when it restarts while loading programs in RAM.

However, if you have a computer that is too slow, then it is not recommended that you start by disabling SuperFetch. In fact, there are less useful and more consuming things that you can disable first. However, it is a feature that you can disable whenever you want, although the option is a bit hidden.
