Windows is no doubt one of the most futuristic and common operating systems. All windows upgrades come with lots of new functions and features, and if you are using windows, then you must have listened to the prefetch of the word and SuperFetch. Basically, prefetch and SuperFetch are two functions that were first introduced in Windows XP and are still used till windows 10.
In fact, the function of both features is very different. Prefetch is basically a feature or algorithm that runs when you boot up your computer. This function basically loads the program files that are frequently-used into the memory so that it can run the program instantly.
SuperFetch is basically an upgrade of prefetch, but this function actually is programmed so that it can take your whole memory to preload the apps and release the memory when needed which can make your PC slow and laggy.
What is the first operating system you have used on a pc? Let us know in the comments below. If we closely look, most people started using PC on the Microsoft Windows operating system. Isn’t it? Windows makes the whole computer usage user-friendly and makes everyone to use a computer without any geeky skills. Before Windows, there is DOS which is another operating system by Microsoft which a completely command-line-based operating system.
We don’t say DOS is worse but every operating system has its own pros and cons. You can still do all the things you are doing on the windows on your Dos too. But it doesn’t have the fancy user Interface and the animations which you are enjoying on the window and many other operating systems which we are using now. Other than that operating systems are come a long way and doing many things that we don’t even know for improving our user experience with it.
Do you know windows services? Or Heard about it? If you don’t we will explain this to you. If you want to use the application on windows, there is no application that is fully independent of the operating system.
Each and every application need some dependency to work on your computer. There are other applications that will need some other background process to work. These background processes are also needed by the operating system which is commonly known as services.
On our daily basis, we are using many services as background processes that are hard to find but it is vital because without these services we cannot able to do all things. If you ever noted that you don’t use any application on your Windows computer but your disk usage and some memory are almost full. I’m sure you will be in this situation. It has many reasons but the most common factor for this issue is the service host fetch.

What is a Service Host?
Host Fetch? Yes! It is a windows service that will learn which applications do you use the most and what time you will open the particular application and learns it over the time you spend with the computer. Later, using this information, this service makes all the files needed to open that particular application which decreases the application loading time significantly.
There are many services like these that are available in the windows which gradually increase the experience of the user. Its main purpose is to speed up the performance of any application you are using. Now you may think, it is a great service to have and what’s wrong with this application. Isn’t it?
I agree this is a great service to have but to have on a computer. But like every other windows service, it has its own set of problems for quite a long time. Really long time and its problem keep on increasing on the further updates. Super fetch was introduced with windows vista and it is present in all the later versions up to the present windows 10.
As I mentioned earlier, it is a background process that can consume our system resources without any user Interface or anything. There is a big problem with it regarding memory management.
In a system that has less than 4GB of ram, many users reported this super fetch spikes the many Ram and CPU usage of the PC. It heavily affects all the intensive tasks like gaming pathetically. It causes shutter and causing frame drops and also causes CPU to continue running on its maximum potential which is not good for any pc.
What is Prefetch and Superfetch?
You can say it can be stopped by the task manager and get rid of this service to improve the performance of the PC. But here is the most tedious thing happening in the windows operating system.
Host fetch is not running on the individual thread where we can simply press the stop button to stop this. Instead, it runs on the collection of many .dll files named Service host. If we force to stop this process, it may cause some other issues in many applications. So, it is impossible to force stop service to fetch completely.
But don’t worry we are here to help you with the 100% disk usage issue of your computer. There are some other ways available from which you can stop this issue. Let us quickly tell you what you need to do for stopping 100% disk usage.
