Many Windows users have noticed that a lot of their system’s RAM is eaten up by the System process. This issue is even seen when the PC is in an idle state.
First, let us understand what causes this behavior. This behavior is because of SuperFetch or Sys main service. SuperFetch service is used to improve the performance of the system by pre-loading the frequently used applications to the RAM. But when the system has a small RAm, this might cause a problem, as most of the RAM is pre-loaded with application data.
Also, there was a known bug with the Superfetch service. However, it has been fixed in the latest Windows build.
