  • Was it simply the service "Superfetch" that was off or did you change some other setting? The service is certainly on by default, but Superfetch has been doing very little work since post-beta builds.

  • HOW DID YOU TURN IT ON? My auto fix can't seem to turn it on and I have endless startup problems. Am getting desperate for a fix.

  • How do you turn it on?  I am running windows 7 and office 7 and for some reason, my superfetch is not running?

    Thanks

  • Were you able to turn it on? My auto fix can't turn it on either.

  • Superfetch does a lot in Windows 7.  It seems to reserve all available ram for caching applications, but releases ram when it's needed.  As admin you can delete everything under c:\windows\prefetch and reboot.  But then you'll have to idle until the layout.ini (Readyboot uses it) file is recreated, and then boot/login 5x to retrain Readyboot, or just let it happen over the course of time.

    This command makes the layout.ini file too and does a boot semi-defrag of every file inside it:

    start /wait rundll32.exe advapi32.dll,ProcessIdleTasks

    I only put the start /wait in to see when it's done (20 min?).

  • For those who want to turn off or on SUperfetch this can by done by the following steps:

    To run this command simpy open windows start menu and in the searchfield type: services.msc

    In this list look for superfetch, and double click on it here you can choose to enable or disable it (more options available but it suggest to just choose for enable).

    Good luck all :)
