Despite its relevant existence to day, Superfetch was long embedded in Windows Vista. Later on, Microsoft develops it as a successor of Windows XP’s PreFetch. Thus, Superfetch is still very much essential to the Windows operation to this day.
Superfetch operates by accumulating caches of each application and program of the PC. By using a lightweight tracking algorithm, Superfetch manages to create a cache data of each one of the applications and programs by compiling it in the Windows (10, 8, and other versions) disk usage. It’s important to note that these data are acquired from the frequency of each application you access every time. In other words, these are the apps you use regularly, either for work or your daily routines. A document based program or a social media application, for instance, may contribute to the cache profiling case of Superfetch considering the amount of time you access them.
SuperFetch monitors every running application on your PC. Whenever you close off an application, SuperFetch proceeds to command the system’s main Memory manager to collect some applications cache memory with the help of disk usage. As a result, the computer system won’t have to take its time to get data directly from the disk when you open the program the next time. In short, Superfetch will manage the launch time of a program by utilizing the existing cache data from the said program.
