Improve Core System Performance (Windows 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.
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.

Note: This tweak may effect some software that relies directly on the Windows swap file such as Adobe Photoshop.
