      Isn’t Superfetch disabled by default in Windows 7 when you have a SSD? I would think it would be a waste of extra disk cycles to enable Supefetch on a device where access is pretty much instant. Not to mention it will decay the life of your drive because you are using unnecessary writes that will shorten the length of your SSD.

      its should be disabled but the services still run with automatic setting

      superfetch writing ?
      i think its more like loading the apps to unused memory before u going to run them

      If you look at the windowsprefetch folder you’ll see exactly what it writes. So yes, it will use your disk as well as the RAM.

      It can be tweaked to cache boot files only, instead of cacheing everything it can think of.

      HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters

      Find the EnablePrefetcher key on the right-hand pane, and change the value to one of these:

      Disable Caching: 0
      Cache Applications Only: 1
      Cache Boot Files Only: 2
      Cache Everything (default): 3
