XP: Registry Hack to Disable or Modify Prefetch
http://www.tech-recipes.com/windows_tips1285.html

In Windows XP there is a Prefetcher component, this shortens the amount of time 
it takes to start Windows and various programs.  When trouble shooting either 
Windows or program start-up issues, it might be better to disable the 
prefetcher, because it runs as a background service while other applications 
are running or loading.

To disable

Start the Registry Editor
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session 
Manager\Memory Management\PrefetchParameters
Double-click the EnablePrefetcher value (remember the value that 
EnablePrefetcher is set to!)
Change the Value data to 0 to disable the prefetcher.
Close the registry editor and reboot the computer for the changes to take 
effect.

When finished troubleshooting/repairing, you can re-enable the prefetcher by 
changing the Value data to its original value.

Values for EnablePrefetcher are:

0 - no prefetch
1 - prefetch applications only
2 - prefetch boot only
3 - prefetch both applications & boot (default)

It may also be useful to periodically clean up the prefetch folder, as it may 
contain obsolete links.  The Prefetch folder can be found in the Windows folder 
on your system drive.  Select all the files, and delete them.  When done, 
reboot your computer.

#####
selain sampah prefetch, buang juga %temp% files
caranya:
1. ketik di Notepad spt ini:

@ECHO OFF
DEL /F /S /Q %TEMP%\*.*
DEL /F /S /Q %systemroot%\TEMP\*.*
exit

2. save as: namafile.bat
3. simpen shortcutnya di folder
   "%userprofile%\Start Menu\Programs\Startup"
