Part1. What exactly is Windows 10 Superfetch?

SuperFetch is a service that was introduced with Vista and has been part of Windows ever since to improve system responsiveness. It tries to speed up your Windows 10 PC by pre-loading parts of programs you use frequently and pre-loads them into fast RAM (random access memory) so that they don't have to be called from slow hard disk drive (Also HDD. It is the alternative to SSD, but SSD is modern and much faster) into memory. The disadvantage was that there was less RAM available to programs but you will gain in better speed.

If turning on the Superfetch won't decrease or degrade your PC's running speed or storage, or you are enterprise users (computer game player) and big data base is frequently needed, or your PC is in SSD installation, you can leave it as it is. However, for personal users, or the one who feel it an obstacle for occupying too much storage place, you are advised to turn it off.
