Windows SuperFetch is a technology in Windows Vista and onwards that is often misunderstood. I decided to delve into this technology to see what it is all about, and to dispel some of the myths surrounding this feature.

Furthermore, from the threads below I understand the IO priority system in windows isn't at the level of quality it would need to be to prevent prefetch from having an adverse effect on the performance of the system.


Indeed. One could only hope for an actual benefit from preloaders if the preloader uses ONLY system resources that are idle at the time. There must be spare (unused) RAM and the CPU and disk must be idle when the pre-loader is operating, otherwise the preloader will reduce speed and responsiveness of the overall system where it supposed to be assisting.
