Disabling Prefetch

Disabling Prefetch.

The prefetch folder is used for speeding up your system. The way it does this is by doing the following:
   * Windows XP is configured to prefetch application and program components so that when you load them to memory; it appears to be very quick.
    * When XP does this the first time, it winds up copying portions of the program to the prefetch area of your local disk.
    * When XP boots up, XP will prefetch portions of the files you use the most.
    * XP loads all associated files, libraries, and pointers necessary to run the program in advance, the preloaded subset makes your system appear quicker.
Even though Prefetch is made to speed up your system. It has a drastic effect on low end machines with little to no memory.

Ok, go to Start -> Run. In the box, type in 'C:\WINDOWS\Prefetch' without quotes. Delete EVERYTHING in there.
Now, go back to Start -> Run. This time, type in 'Regedit' again without quotes. When the Registry Editor Dialog box opens, navigate to this value:

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

In the right side pane, look for the key named EnablePrefetcher. Double click it and a window should appear. Change the 3 to a 0. Click OK and then reboot. Done. :D
