How to startup the operating system and the programs faster using Superfetch in Windows Vista or Win 7


19.10.2009

Windows XP was able to boot very fast because of the Prefetch option. Sadly this option didn’t have any influence upon the applications that were installed in the system.

For this reason, in Vista, Microsoft had developed and implemented the Superfetch option.

This new option is taking into account when the computer is started, not only the operating system files but also the most used programs that you have installed.

In this way the applications or programs will be available to use much faster when needed.

Superfetch is supposed to work perfectly at the end of a new fresh install of either Windows Vista or Windows 7.

Despite this, you won’t have anything to lose if you check that everything is in order, because majority of the “tuning” programs are “playing” with this kind of options.

So open the registry editor ( Start|Run|regedit|OK ) and navigate to the registry key HKEY_LOCAL_MACHINESYSTEM|CurrentControlSetControlSessionManagerMemory ManagementPrefetchParameters. Here you will find the entry EnableSuperfetch. Double click on it and check what’s her value.

3 is the correct option that enables both the OS files needed to boot and the Installed applications

If it is 3, then everything is Ok, beacause this number takes into account the OS files needed to boot up and the most used programs. 2 is only for the OS files, while 1 is only for the installed applications.

Is not recommended, but you can also use the 0 (zero) value, which disables the option.
