Well (this doesn't apply to me) some people aren't comfortable in editing the registry and the application I mentioned (NVTweak) allows individual control over the driver tabs as well as various other options.

Quote from the author...
"I realize everyone will have different preferences to what options they will use in the control panel. So instead of working on a .reg file (most people don't know how to edit that), I just make an executable that people can use to set up their own configuration quite easily."
(This tweak is intended for use with GeForce/Quadro cards and ForceWare 55.xx - 7x.xx 3D Stereo drivers. NVTweak is not fully compatible with Windows 98/Me or driver versions older than 55.xx.)

P.S. Sure, it's a large file, but it's not a memory resident thing, it's just a "control panel" for controlling the things that the coolbits files enable.
