Prefetch and Superfectch are that services that determine which app or software you will open. As per the statics based on your previous working pattern, it will use the memory to get ready for your PC for that software or app. So that you can have a better and smooth experience. As it helps to improve the experience, it can also take a large amount of the hard disk space. This high disk space usage can be resolved by disabling these services.

• Now find the Surperfetch in the list of services.
• Once you find it, tap-right on it, and select Properties.
