Microsoft Vista and above supports memory priorities. A lower priority means that the memory will be freed from the standby list sooner than other memory. The default priority is 5 and very few applications lower their priority. Some system utilities, such as SuperFetch, use different memory priorities, however this is rare. The SysInternals tool RamMap provides a way to view the memory priority of file pages.

This release consists of a GUI tool that performs the file mapping. A screen shot is shown below
