What Is SuperFetch? How It Works
The official description of the SuperFetch service says that it “maintains and improves system efficiency over time,” however that’s obscure and doesn’t clarify the entire story.
SuperFetch is a function that was launched again in Home windows Vista. It sits quietly within the background, continuously analyzing RAM utilization patterns and studying what sorts of apps you run most frequently. Over time, SuperFetch marks these apps as “regularly used” and preloads them into RAM forward of time.

By default, SuperFetch is designed to take up all of your obtainable RAM area with preloaded apps. Don’t fear: it solely offers with unused reminiscence. As quickly as your system wants extra RAM (e.g. to load an app that wasn’t preloaded), it relinquishes the wanted reminiscence as needed.
Be aware that SuperFetch shouldn’t be the identical factor as Prefetch, which is the preloading reminiscence supervisor that was launched again in Home windows XP. SuperFetch is definitely the successor to Prefetch. What’s the distinction? Prefetch didn’t analyze utilization patterns over time and alter its preloading parameters accordingly.

It’s unclear why this occurs as a result of it doesn’t happen for everyone, however we suspect it has to do with RAM-heavy video games that continuously request and unencumber reminiscence, which can trigger SuperFetch to continuously load and unload information.
