It's the one feature I really hoped to see added in SP1 for Vista, but thus far it has not been added. There are third-party tools designed to reduce the tenacity of UAC, and SP1 reduces the average number of prompts from four to one, but for the time being there is no way to white-list a program.
Is there a way to disable the User Account Control warning screen for only one program? I know how to disable it completely but that's not what I want. There is one program I trust that I want to run as an administrator every time (can do this in properties) but I don't want the warning screen every single time.
