使用 C# 调用另一个进程时避免 UAC 提示

Question

I'm developing an iventory software for my company that demands administrative rights (WMI calls, registry access, etc.). For convenience I do no want the UAC to prompt the user for clearance to execute the app (yes, I must force the app to run even if the the user doesn't want), and I can't disable the UAC via GPO (would be perfect but a pain in the ass). I first tried to pass an AD administrative account credentials to the inventory software using another process (Processinfo on C#) but the UAC prompts remained. After a few research I discovered that if use the local Administrator credential it wouldn't give me any annoying prompt but since my company's environment is a mess, there are many stations with different credentials other than the standardized. Does anyone have any idea of how I could do this? (Using .net C#).

I have accomplished this using the Task Scheduler Managed Wrapper . Be sure that you provide the local administrator group credential in setting up the task. Here's how I do it in my code:

        using (TaskService ts = new TaskService())
        {
            try
            {
                //Create a new task definition and assign properties
                TaskDefinition td = ts.NewTask();
                td.Principal.RunLevel = TaskRunLevel.Highest;
                td.RegistrationInfo.Description = "Paulos Task";
                td.Triggers.Add(new TimeTrigger() { StartBoundary = Convert.ToDateTime("01-01-2003 00:00:01") });

                // Create an action that will launch PauloApp whenever the trigger fires
                td.Actions.Add(new ExecAction("PauloApp.exe", "", Environment.ExpandEnvironmentVariables(@"%ProgramFiles%\Paulo")));

                td.Settings.DisallowStartIfOnBatteries = false;
                td.Settings.StopIfGoingOnBatteries = false;

                ts.RootFolder.RegisterTaskDefinition("PaulosTask", td,
                   TaskCreation.CreateOrUpdate, "Administrators", null,
                   TaskLogonType.Group);

                // Register the task in the root folder
                Microsoft.Win32.TaskScheduler.Task t = ts.FindTask("PaulosTask");
                if (t != null)
                    t.Run();
                else
                    //could not find PaulosTask
            }//end try
            catch (Exception e)
            {
            }
        }//end using
