    This is just rumor...probably false...still...

    I read that Longhorns "Superfetch", a prefetch that is more advanced than XP's Prefetcher is actually already functional in XP, provided that the instruction to activate it is present in the registry. The rumored key is this:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\Prefetcher

    the value name and data are

    EnableSuperfetch and 1

    it is suggested to leave your normal XP EnabablePrefetcher settings stand
    (do not delete this key, in other words, and usually value is set to 3)
    ---------------------------------------------------------------

    my guess that if true this will probably only work in sp2. I say that because I have sp1a and my key is named slightly differently, e.g.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters

    XP Prefetcher usually is set up with the parameters set this way:

    EnablePrefetcher is set to 3.
    ----------------------------------------------------------------------
    Here's an interesting Prefetcher fact for us services tinkerers:

    Did you know that if you deactivate the Task Scheduler Service, then
    The prefetcher function will stop updating its prefetch files and Layout.ini?
    Do you care?

    That is a pretty well established fact, so I place it here to offset my shameless rumor!

    See the "EnableSuperfetch Tweak" and "EnablePrefetcher Tweak" on this page: XP Myth ;)

    well if the rumor is as true as the assertion that xp runs fine on a 64mb machine i might just take my chances!
