What is SuperFetch?
SuperFetch is a sophisticated background process in Windows 10 designed to predict and pre-load frequently used applications and files into your computer’s RAM. By anticipating your needs, SuperFetch aims to speed up application launch times and overall system responsiveness.
Imagine you frequently use a specific software like Microsoft Word. SuperFetch, observing your usage patterns, might pre-load Word’s files into your RAM, allowing it to open faster the next time you need it. This proactive approach eliminates the need for the system to retrieve files from slower storage devices like your hard drive, leading to quicker loading times.
How Does SuperFetch Work?
SuperFetch employs an intelligent algorithm that analyzes your usage history and predicts the applications you’re likely to open next. It keeps track of the frequency, time of day, and context of your program usage. Based on these patterns, SuperFetch strategically pre-loads files into RAM.
For example, if you typically open a specific game after your lunch break, SuperFetch might anticipate this behavior and preload the game’s files into RAM before your lunch break ends. This proactive approach can dramatically improve the game’s launch speed and overall gaming experience.
