[QUOTE="Jaspion, post: 908934, member: 8794"] Disabling the service will disable more than just superfetch. Prefetch also depends on this service, so if you disable it you will also prevent the prefetch folder and layout.ini file from being populated/updated, which in turn means your defrag tool won't be able to optimize the file layout properly. In order to disable superfetch but not prefetch, you have to use the registry. [SPOILER]HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters\EnableSuperfetch 0: Disabled 1: Apps only 2: Boot only 3: Apps and Boot (default) Setting it to 0 or 2 will stop the disk thrashing.[/SPOILER] I've been using it for boot only, and I've also disabled memory compression. For my old HDD laptop, with little CPU power and sub-optimal battery life, it's just better and more stable. Edit: For most modern computers, though, I'd assume leaving settings to default is best.
