Hello,
Now in this days many users are using Windows 7 but there are many others are still using windows xp, So this trick for those users.
Start Registry Editor (Regedit.exe).
Locate the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement\PrefetchParameters
Make sure you backup the keys by exporting them to a .reg file.
On the EnablePrefetcher value, change the setting from 3 to 5 (decimal).
Close the registry editor.
Restart your computer.
Thats it!
