Speedup Windows XP By 15% Using Longhorn’s Enablesuperfetch

Everton | Aug 25, 2005 | View Comments


One of the many claims Microsoft makes for Windows Longhorn/Vista is that it will launch applications 15% faster than Windows XP does currently. This is down to improvements in the Prefetch functionality.Well, there’s no need to wait until Longhorn arrives; this improvement is already in Windows XP thanks to Service Pack 2. It just needs to be turned on.

To enable super prefetch:

  • Use a registry editing tool to navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\PrefetchParameters

  • Insert a value with the following details:

Data Type: DWORD

Value Name: EnableSuperfetch

Value: 1

If you are not comfortable editing your registry then please do not do this!

    This does NOTHING, This is "tweak" is a MYTH: XP Myths
    Please stop spreading this crap around.
    This myth was started when the Inquirer irresponsibly ran a bogus letter without doing any fact checking. Windows internals guru Mark Russinovich said this won't work, the "Superfetch" string isn't even in the Windows XP kernel. You can confirm this yourself by checking with the strings.exe utility. This makes it impossible for it to do anything since no "Superfetch" command exists. Windows cannot execute a nonexistent command and will simply ignore it. Anyone who says this works is not only lying but a fool.
