"I am happy to report that rolling the above setting swith the 6350 worked on the machine I re-imaged. I created a reg file and a new package in SCCM with that as its contents. Using a cmd /c reg import file.reg command line action to apply on machines that are an OptiPlex 790 with a Radeon 6350 video card. No UAC prompt! Thanks a bunch for your information wbracken. Again, hope an updated driver comes out soon so we don't have to do this reg hack any longer."
