User-mode and kernel-mode drivers and kernel-mode system code are usually written to be either pageable or non-pageable. In cases where drivers or system code is pageable, you can use the following registry entry to keep this pageable code in RAM, but this is only advisable on systems with extremely large amounts of RAM.

If your system has enough physical memory, performance will increase if the operating system does not page itself to disk. The best way to make sure is to load all of your applications and use the task manager (press Control-Alt-Delete) and click the performance tab. Your physical RAM should be greater than the Peak Commit Charge by at least 16MB.

To enable this feature, manually edit the following registry key.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Memory Management and set the following value: DisablePagingExecutive=1
