Windows SuperFetch in Windows Vista uses a new version of the technology SuperFetch, which provides a common starting used in applications with high compared with Windows xp speed. SuperFetch technology works in the background, some time watching how your computer. After that, based on your model of computer use, it determines which applications are cached in memory in the first place. SuperFetch technology also gives the most frequently used applications, a higher priority than background tasks, so that the system quickly responds to your actions, even if you leave your computer on for a while and just returned to him. SuperFetch technology allows the notorious problem of "dinner" faced by users of Windows xp and earlier versions of Windows: when the user goes to lunch or for a long time, the operating system is left to itself. Depending on the version of the os, the system removes the most recently used applications from the cache and can begin work on background tasks. When the user returns to the computer, any time the system is running slowly, as if tired of the long downtime.
In the case of Vista, the problem does not arise. Moreover, Vista is so "Savvy" that understands which applications you may need at any given time of day, and pre-caches, providing increased speed. As far as I know, you can not configure Windows SuperFetch.
