Automatic. It pre-loads parts of programs before you do, based on your usage, to load commonly used software faster.

The memory space it "reserves" isn't reserved, and Windows will free part of it (or full, if you need it) even before you come close to needing it.

Should i have it on or disable it?

It caches commonly used software. About the only drawback is a bit of power usage. Its the ultimate upgrade to the application caching Windows came with for a decade, rather than waiting for the first load of a program it would pre cache the most commonly used stuff making everything load like it was in RAM. Why would anyone turn that off?!!!

Because it needs CPU time to handle the cache. Not sure how much, but (efficient as well as effective) caching is a complex task to do and is usually done in HW to help the CPU not starving for data. But when you consume CPU time to hopefully save time in the future this can turn out badly quckly.

Mineral oil and 40 kg aluminium heat sinks are a perfect combination: 73 cores and a Titan X, Twenty Thousand Leagues Under the Oil
