SuperFetch is a system of RAM management that preloads your installed memory with your most frequently used programs.
It's designed to improve performance, though some gamers and specialist users have claimed to notice speed gains after disabling it. As the technology adapts to your usage patterns, though, it's more likely that disabling SuperFetch will make your system feel more sluggish.
SYSTEM LAYOUT: The 'Layout.ini' file contains details of the files accessed during boot time and the order in which they are used
It also examines differences that occur at different times of the day, so the preloaded applications for morning use may be quite different to those that you launch for some evening recreation.
Just as it does during boot, the service takes note of which files are accessed in which order when each application is launched, making sure that these are available in RAM when called upon.
If you still want to, you can disable SuperFetch in the same way that you disable any other service. Click 'Start', enter services.msc into the Start menu Search and press [Enter]. This opens the Services utility on a console. Scroll through the services until you find SuperFetch. Double-click it and click 'Stop' to stop the service.
To permanently disable it, select 'Startup type: Disabled' and click 'OK'. Think carefully before you take this step, though, because SuperFetch is a somewhat misunderstood service.
Despite the fact that it's been tipped as a candidate for disabling in online articles, doing so could have the reverse effect to the one desired.
