Disable Screen Flicker/Blacking out before UAC Prompt
You might have noticed you screen black out or flicker before the User Access Control (UAC) prompt pops up. This is not a bug but it is a security feature to grab your attention. Of course like the many other things in Vista that you don’t think, you could disable this blacking out or flickering too.
Disable Windows Vista UAC (User Access Control)
User Access Control has turned out to be a nuisance rather than a security enhancement for many people. UAC requires all users to run in the standard mode rather than in Administrator mode. This minimizes the risk of a user/program accidentally making system wide changes that could corrupt the OS. So UAC blocks and prompts for the Administrator approval for any system wide changes. Therefore with UAC silent installations won’t be silent anymore as the user will first be prompted by UAC to allow or disallow the installation.
