Place The Windows Kernel Into RAM to disable paging and run faster than before

Anything that runs in RAM will, of course, be faster than something 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—but only if your system has 256 MB or more of RAM. Change the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\MemoryManagement\DisablePaging Executive   to “1” to disable paging and have the kernel
run in RAM. Set the value to “0” to undo the hack). Exit the Registry and reboot.
