    Utility capable of managing Prefetch and Superfetch in Windows XP, Vista and 7.

    TweakPrefetch allows the user to set separate parameters for Prefetch and Superfetch.

    The available options are:
    • Disabled: completely disables fetching. “ Superfetch” service is disabled.
    • Applications Only: fetching will only be applied to user started applications.
    • Boot Only: fetching will only be applied to boot files (system files, services and startup programs).
    • Applications & Boot: fetching will be applied to both applications and boot files (Windows default setting for Prefetch and Superfetch).

    Moreover, “ 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). 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.

    If you notice that Windows won´t rebuild the “ Layout.ini” file after you have cleaned the Prefetch folder, or maybe you just want to update it to your latest startup configuration, you can force the process using the “ Rebuild Layout.ini” function in the “ Options” menu.

    TweakPrefetch will also detect wrong parameters for Prefetch and Superfetch, and will let the user fix them with a single click.

    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.
