Waco Posted May 5, 2011 Posted May 5, 2011 I'm pretty sure turning on the large data cache does something similar - it's just not preemptive. Share this post Link to post Share on other sites More sharing options...
wevsspot Posted May 5, 2011 Posted May 5, 2011 Preemptive - one of my favorite words. Like I'm going to preemptively punch you in the nose because I know you are going to cut me off in traffic Share this post Link to post Share on other sites More sharing options...
My_Inner_Fred Posted May 5, 2011 Posted May 5, 2011 Nice guide, It'll definitely help ppl who use SSDs. I forgot where I go to access Superfetch options. Share this post Link to post Share on other sites More sharing options...
wevsspot Posted May 5, 2011 Posted May 5, 2011 I forgot where I go to access Superfetch options. For Superfetch only there are two options; In the Services menu or via a direct registry edit. However, for prefetch you can enable/disable via the registry. To disable Superfetch using the Services menu In the Win7 quick search box, type "services.msc" without the quotation marks Scroll down to Superfetch and enable or disable Via the registry editor; HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters\EnableSuperfetch Edit the DWORD (in hexadecimal) If you wish to modify the Prefetch settings; HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters\EnablePrefetcher Edit the DWORD (in hexadecimal) The hexadecimal values you can choose from for both Superfetch and Prefetch are; 0: Disable SuperFetch 1: Cache applications only 2: Cache boot files only 3: Cache everything (default) Share this post Link to post Share on other sites More sharing options...
