While you should not disable the UAC prompts for the whole computer, you may want to disable it for certain applications. Using the Microsoft Application Compatibility Toolkit and following the steps below, you can disable the UAC prompts for one or more specific applications which you trust. This will NOT disable the User Account Control feature for the whole computer.
