We start with a simple hack .Type "regedit" in the Run Command Box from Start Menu.This hack will load applications faster.The Windows prefetcher aims to load applications faster bt "prefetching" the application and storing it in the pre-fetch cache.You can speed up the application loading by changing the default value of one the settings under the relevant key.
Navigate to :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
The default value of the EnablePrefetcher setting is 3.Change this value to 5 to make application load faster.You can also experiment with higher values upto 9 and can see whether you get any improvement or not.
