title: UWP remove "exit-full screen" in Control Box
body: <p>Is there a way to remove the "Exit-Fullscreen" button in UWP apps?</p>
  
  <p>I know it is possible, as one app "4 pics 1 word" has done it. Below is a screenshot:</p>

  <p>As you can see, there are only 2 buttons in the control box: Minimize and Close.</p>
  
  <p>However, for other apps, there is another button that appears:</p>
  
  <p><a href="https://i.stack.imgur.com/ghTDb.png" rel="nofollow"><img src="https://i.stack.imgur.com/ghTDb.png" alt="enter image description here"></a></p>
  
  <p>There are 3 buttons, Minimize, Close, and a new one, exit Full-Screen.</p>
  
  <p>For resolution concerns, I would like my app to <strong>always</strong> be Full-Screen and not allow any option to exit full-screen. Alt-tab is okay. </p>
  
  <p>Is there a way to do this?</p>
  
  <p>Thank you</p>
