TweakPrefetch 2.2.0.1 is a System Optimizer product from exilesofthardware.blogspot.com, get 5 Stars SoftSea Rating, This program is a software capable of managing Prefetch and Superfetch in Windows XP and Vista, now it can run under Windows 7. This is an easy-to-use software that is designed to manage you system's fetching. It allows the user to set separate parameters for Prefetch and Superfetch.

Note: emptying the Windows/Prefetch folder is not recommended and will cause a temporary performance drop in applications startup time. I added this function to allow advanced users to reset Prefetch data in case it might be necessary. Prefetching in Windows XP is better left at its default value for the 99% of the users.

However, someone prefers to set it to "Boot Only", in order to benefit from fetching only at boot time. For what concerns Windows Vista, default settings are still recommended for most users (especially for who doesn't use the PC for gaming).

Advanced users and gamers might want to disable Superfetch (to obtain an XP-like fetching, reduce hard disk trashing and prevent this function to interfere with games) or set it to "Boot Only" at least. Obviously, it's up to the users to experiment different settings and tweak fetching at their advantage

Features:
1. Disabled: totally disables fetching. "Superfetch" service is disabled.
2. Applications Only: fetching will only be applied to user started applications.
3. Boot Only: fetching will only be applied to boot files (system files, services and startup programs).
4. Applications & Boot: fetching will be applied to both applications and boot files (Windows default setting for Prefetch and Superfetch).
5. "Clear Prefetch" function is included: it will empty the Prefetch folder, forcing the operative system to rebuild fetch data (or not to create them at all if Prefetch has been disabled).

Just launch the software and it will load up instantly. It has the following options:
1. Disabled: totally disables fetching. "Superfetch" service is disabled.
2. Applications Only: fetching will only be applied to user started applications.
3. Boot Only: fetching will only be applied to boot files (system files, services and startup programs).
4. Applications & Boot: fetching will be applied to both applications and boot files (Windows default setting for Prefetch and Superfetch).

Even thought disabling superfetch is not recommended users(specially gamers) might want to disable it so that it does not interfere with games and also reduce hard drive trashing. If you feel reluctant then you can set it be to Boot only.

In Windows XP Microsoft introduced Prefetch which helped programs load faster by caching the programs in the memory. It reads the user's behavior and cache the most used programs in the memory, thus speeding up the launch the next time you use the program. Superfetch was introduced in Windows Vista and is a more advanced version of Prefetch.
