latest nvidia drivers 6800

We are finding that the latest nVidia beta drivers for Vista are not usable. How do I get them completely uninstalled from the system, and the original Microsoft video drivers re-installed? After removing the nVidia drivers, upon rebooting you have what looks like original Microsoft drivers. But you lose all of the mini applets from the right pane of the desktop and you get messages that those are no longer working. In Device Manager, I don't even see a category for display adapters!
I need to do a complete reset on the video driver install. Is there a clean way to do it other than re-installing the whole OS?

Have you tried the Add Hardware applet in the Control Panel. It should detect and install the signed drivers for the video card. Or from the device manager, you can right click your PC name and try scan for new hardware. If Windows loaded correct drivers at install it should detect your card and reinstall drivers. I just noticed something trying this with the Add hardware that is interesting *for this machine* so might suggest the device manager option first.
