The Superfetch service in Windows is known to maintain and improve the performance of the system overtime.  It quietly runs in the background, analyzing RAM usage pattern and the applications you frequently use.

Over time Superfetch service marks these apps as “frequently used” and preloads them in memory. The result is the Windows operating system isn’t required to load them from the hard drive (which is slower) and the whole process of launching apps is much faster and responsive.

Why disable Superfetch service?

Though Superfetch service is intended to improve the performance of Windows, it sometimes also degrades its performance.  By default, Superfetch service is designed to take up all unused memory for all apps.  However, whenever the system needs memory, Superfetch frees the needed memory.

If you notice Superfetch is using too much of CPU and RAM resources and slowing down the system, you can disable it.  You can disable Superfetch service without any fear and it does not  impact the performance of the Windows operating system.
