When I checked this registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\MemoryManagement\PrefetchParameters\EnablePrefetcher
it was set to 5. Searching the MSKB returned nothing on this setting. Does anyone know what the 5 parameter does?

0 ‐ Disable Prefetcher
1 ‐ Application launch prefetching
2 ‐ Boot prefetching
3 ‐ Both application and boot prefetching

but I've seen that some optimization programs like to set it to 5 for some reason. It is either undocumented, or does nothing. Sometimes these settings are additive, but in this case, 3+2 would still be the same as 3.

Make your prefetcher folder empty permenantly.
