SuperFetch feature loads most frequently used applications into RAM to make faster loading time for those apps. Is there any way to tell SuperFetch service to load specific apps into RAM in Windows 7? For example, I'd like to load a game into RAM using SuperFetch so that whenever I launch the game I'll get faster loading time. Thanks in advance.

The only control you can do of the SuperFetch feature is via the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters, which contains EnablePrefetcher that may have the following values:

  • 0 : To completely disable the SuperFetch feature
  • 1 : To optimize only application startup
  • 2 : To optimize only the computer startup process
  • 3 : To optimize both application startup and the computer startup

This is the only control you have. Its default value is 3, and should be left like that.

The rest is automatic: If you use a certain application a lot, it will be prefetched when Windows sees fit according to how it analyzed your usage patterns. For example, it might prefetch some applications immediately after boot, and others only in the morning.
