Superfetch, called SysMain on Windows 10, is an important system process that increases the speed of Windows. It preloads the apps and software you frequently use from the hard disk to the RAM, thus considerably reducing the time of loading.

Superfetch also keeps a track of apps which you use on certain days or if there is systematic usage. In case, you use a different set of apps each day of the week, Superfetch will work accordingly and load the distinct set of apps each day. It is beneficial for those obsessed with speed and who do not want to waste time on the loading of apps and software.

The background apps continue to function when the system is idle but as soon as they are finished, it again loads the frequently used apps. This ensures a lower loading time of apps when working on the system.

Since Superfetch always works in the background, it can also cause multiple issues to a system, namely overheating and constant excessive utilization of disk space.
