Microsoft Windows 10: Lock pages in memory

This policy setting determines which accounts can use a process to keep data in physical memory, which prevents the computer from paging the data to virtual memory on a disk. Normally, an application running on Windows can negotiate for more physical memory, and in response to the request, the application begins to move the data from RAM (such as the data cache) to a disk. When the pageable memory is moved to a disk, more RAM is free for the operating system to use.
