SuperFetch

SuperFetch is a memory management tool in some of the newer Windows operating systems beginning with Windows Vista. It helps the system to manage random access memory (RAM) and allocate it across various applications for efficient performance.

SuperFetch builds on the previous success of a tool called PreFetcher in Windows XP, and directs the use of data from often accessed applications to be processed by fast RAM components.

Prior to the development of these new memory management items in the operating systems themselves, users sometimes relied on outside third-party standalone memory management systems to allocate RAM.

Some of these tools can purge active memory or otherwise help optimize in between user sessions. Now, experts point out that with the development of internal additions like SuperFetch, fewer of these external tools are needed.
