How do I revert to the standard VGA drivers?

I want to revert back to the standard VGA drivers because I want to install the latest ATI drivers.

What happens is I uninstall the ATI drivers, there is no option to delete the drivers (maybe because they are the WDDM drivers). Windows immediately re-detects the hardware and installs the ATTI WDDM drivers! This is annoying, because I want to be able to choose.

I either need to know how to just get to plain vga drivers, or better would be where the option is burried that will have windows give me the choice to autodetect and autoinstall drivers for me.

Thanks
