Disable Superfetch in Windows 10, 8 and 7

We can easily Disable Superfetch but first let us know about Superfetch like what is it and what is its role in our Computers. Superfetch feature was introduced for the first time in Windows Vista. It runs in the background and analyzes the usage pattern of RAM.

Also, it keeps an eye on applications that you use more often. In other words, Superfetch make a note of apps that you use more often and mark them as “frequently used”. And then load these apps into RAM before time.

Hence, when you run the app you have visited before, it will launch faster because it is already preloaded in memory.

Superfetch use all your RAM space which is available but it uses only unused memory. So whenever some application needs RAM it free out some memory.

Two goals of Superfetch are:

1. It decreases the time to boot.

2. Load the applications efficiently that you use the most.


What is Superfetch?

Superfetch runs very smoothly that you even can’t notice in case you have a system with average or high specifications. But there are many problems associated with Superfetch. Some of them are described below:

1. As Superfetch is always running in the background, it is always using some part of CPU and RAM.

2. Also, Superfetch relocate the loading to an earlier time and it doesn’t abolish the need to load apps into RAM. Hence, when the loading takes place, your system will experience a slowdown.

3. When Windows 10 is installed on an SSD (Solid State Drive), then the performance of Superfetch is not visible because SSDs are very fast and also improves performance.

4. If you are a gamer and love playing games on the computer, then you should know that Superfetch also causes performance issues while playing games. This happens mostly in case if your system has 4 GB RAM or less. This happens because heavy games require Superfetch to load and unload data constantly.
