title: Windows 7 UAC warning message causes
body: <p>We've started testing an application on Windows 7. We first got the "unknown provider" message.  We signed the application and now get a message:  </p>
  
  <blockquote>
    <p>Do you want to allow the following program to make changes to your computer? </p>
  </blockquote>
  
  <p>None of these messages were generated in Vista.  I know UAC is enhanced in Win 7.  It has been difficult to find out what's actually causing these messages.</p>
  
  <p>I've searched the web and not come up with a good list of what generates this second message.  Does anyone have such a list?  Also, does anyone know if this message is generated when the application is trying to access the system in an unapproved way or is the flag somehow compiled into the application?  </p>
