Keep Core Windows Operating Data in Main Memory

This tweak forces core kernel and essential driver files to stay in the RAM, rather than being shoved into virtual memory on the hard drive. In the conversion over to virtual memory, performance can drop significantly.
This transfer over to virtual memory is designed to be put into effect when the system is getting low on physical RAM, however, this occurs periodically even when the system is not low on memory. In those cases, the transfer over to virtual RAM is often not necessary. Only proceed with applying this tweak if you have at least 256MB of RAM in your system.

Open regedit and go to HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Control/Session Manager/Memory Management. Double click on DWORD value “DisablePagingExecutive” and set the value to 1.
