This article describes how to prevent pageable drivers and system code in the Windows NT Executive from being paged out to disk. Although this decreases the response time in systems with extremely large amounts of physical memory (RAM), it is critical that there is enough RAM installed, otherwise the server could be rendered unstable.
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
User-mode and kernel-mode drivers and kernel-mode system code is 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.
