Prefetch is designed to speed up program launching by preloading programs into memory - not a good idea is memory is in short supply, as it can make programs hang. To disable prefetch:
1. Click ‘Start’ then ‘Run’ 2. Type in ‘Regedit’ then click ‘Ok’ 3. Navigate to ‘HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters’ 4. Right-click on “EnablePrefetcher” and set the value to ‘0′ 5. Reboot.
