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.
Note : These tips may not necessarily speed up your system. But most of the times they work perfectly. Use them carefully.

VERY BAD IDEA, DO NOT DO THIS!!.
This "tip" is based on a complete misunderstanding of how prefetch works. Prefetch does NOT preload applications at bootup. Prefetch files are referenced only after application launch has been initiated. Using information gained on previous program launches Windows is able to use the prefetch file to optimize the process. No memory is ever wasted. Prefetch will be of value even with only 64MB of RAM.
The default and optimum value for EnablePrefetcher is 3. Setting it to 0 will impair both boot and application launch times and has no benefits. This will further impair performance on a system that is already impaired.
All of this has been extensively tested.
