Well, you can turn off Prefetch then delete the entire folder, then turn it back on if you want. XP will recreate and start repopulating it.

I have it turned off on my systems, makes them a little faster over all.

Click on Start then Run, type regedit and press Enter
Navigate to:

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

Set the value to 0

To restore, set the value to 3.

As always, before you make any changes to the registry, please back it up. An excellent way to do this is to install ERUNT. Let it add an entry to your Start menu during the install process. That will allow ERUNT to backup your registry each time you boot. It only takes a few seconds and has no real impact on boot time. Run ERUNT immediately after installing it to create a full registry backup.
