Vista - Change threshold on Resource Exhaustion Detector and Resolution(RA

I’m using Vista Ultimate 64 (SP1), and I’d like to change the threshold that
Resource Exhaustion Detector and Resolution (RADAR) goes into low memory mode
from 80% to about 95%.

This article describes the fix for Windows 2000 Datacenter Server
http://support.microsoft.com/kb/811308 but I doubt that this applies to Vista.

I am aware that this is probably not reccomended by Microsoft, but I’d like
to try it anyway, and take full responsibilty for anthing that goes wrong if
i do this.

If anybody out there could help I’d appreciate it.
