Place Windows Kernel into RAM

It’s a given that anything that runs in RAM will be faster than an item that has to 

access the hard drive and virtual memory. Rather than have the kernel that is the 

foundation of XP using the slower Paging Executive functions, use this hack to create 

and set the DisablePagingExecutive DWORD to a value of 1. Perform this hack 

only if the system has 256MB or more of installed RAM! 

Edit the Registry key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\

Memory Management\DisablePagingExecutive 

Set that to 1 t

o disable paging and have the 

kernel run in RAM (set the value to 0 to undo this hack).

 Exit the Registry and reboot.

NOTE :- Take the backup of your registry (by one of these Software's) before doing any tweak.
