    I grabbed this tweak from another thread hoping for a response if at all possible.

    The post below lists 0, 1, 2, or 3 as options for the prefetch value. When I looked at my current registry value it is set to 5?? Anyone know why this may be or if it is OK? Should I set it to 3 or does it make a difference? Thanks in advance...

    hello, everyone... I've got a few tweaks and info to add to this great thread...

    1. link to Laurens "Prefetcher"-tweak

    This is an unique technique for XP, which could improve the performance significantly by tweaking the prefetcher. Recommended hardware: PIII 800 or higher, 512M RAM or more.

    1. run "regedit";
    2. goto [HKEY_LOCAL_MACHINE\SYSTEM\Cur

    rentControlSet\Control\Session

    Manager\Memory Management\PrefetchParameters\

    EnablePrefetcher];
    3. Set the value to either 0-Disable, 1-App launch prefetch, 2-Boot Prefetch, 3-Both ("3" is recommended).
    4. reboot.

    It will decrease the boot time but double and increase the performance of your XP. Try it!

    Any value other than 1-2-3 will disable prefetch

    definitely set it to 3

    :)

    I've just tried it and my comp shuts down and starts up alot quicker. The speed is about the same.

    BTW my current registry value it is set to 3 was 5

    Cool

    it is quicker :)

    Strange how the values are set to 5

    I've never come across it before ??????

    Perhaps a tweaking program has changed the settings ????

    :confused:

    The default value is 3. There was however a tweak around on the net for a while recommending to set it to 5, which actually disables prefetch. Perhaps some makers of tweaking utilities included this wrong information in their programs. If you want prefetch make also sure that taskscheduler service is running, it depends on it.

    How do you make sure task scheduler is working again? Thanks

    Some time back there was an erroneous "tweak" circulating the web that suggested changing the prefetch registry setting to "5". The only settings the system will recognize are:

    0 = disabled
    1 = application launch cache
    2 = boot launch cache
    3 = both

    anything else doesn't work.
