Answer 1

The way I do it is by creating a DTF custom action that calls the dism.exe process. You get the same result and no command prompt is launched.

[CustomAction]
public static ActionResult RunDism(Session session)
{
    session.Log("Begin RunDism");
    string arguments = session["CustomActionData"];

    try
    {
        ProcessStartInfo info = new ProcessStartInfo();
        info.FileName = "dism.exe";
        session.Log("DEBUG: Trying to run {0}", info.FileName);
        info.Arguments = arguments;
        session.Log("DEBUG: Passing the following parameters: {0}", info.Arguments);
        info.UseShellExecute = false;
        info.RedirectStandardOutput = true;
        info.CreateNoWindow = true;

        Process deployProcess = new Process();
        deployProcess.StartInfo = info;

        deployProcess.Start();
        StreamReader outputReader = deployProcess.StandardOutput;
        deployProcess.WaitForExit();
        if (deployProcess.HasExited)
        {
            string output = outputReader.ReadToEnd();
            session.Log(output);
        }
        if (deployProcess.ExitCode != 0)
        {
            session.Log("ERROR: Exit code is {0}", deployProcess.ExitCode);
            return ActionResult.Failure;
        }
    }
    catch (Exception ex)
    {
        session.Log("ERROR: An error occurred when trying to start the process.");
        session.Log(ex.ToString());
        return ActionResult.Failure;
    }
    return ActionResult.Success;
}

DISM parameters are set via the custom action data.
