Speedup Windows XP By 15% Using Longhorn’s Enablesuperfetch

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!
