SuperFetch is a memory management trait added in all versions of the Windows operating system from Vista to Windows 7, 8, and 10. An initial version of this built-in caching tool called PreFetcher was prefaced in Windows XP. This trait did not predict future RAM usage. A more energetic version of this pre-launching service debuted with Vista, and Microsoft has relied upon it since to store frequently-used applications more promptly. Modern versions also observe the times of day at which you reach different programs to preload the apt application code and data to allow faster loads of general applications.
