Improve Core System Performance (Win NT/2000/XP)
 

On systems with large amount of RAM this tweak can be enabled to force the core Windows system to be kept in memory and not paged to disk.

Open your registry and find the value in the key below.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro lSession Manager\Memory Management]DisablePagingExecutive

(0 = default, 1 = disable system paging)

Change the value to '1' enable the tweak and stop the core process from being paged, or set it to '0' for the default.

Restart Windows for the change to take effect.
