title: exe icon is not full size (windows 10)
body: <p>I want to set an icon for my program (exe file and desktop shortcut). I am using Qt 5.7 on Windows.
  I followed the instructions from: <a href="http://doc.qt.io/qt-5/appicon.html" rel="nofollow noreferrer">http://doc.qt.io/qt-5/appicon.html</a>, that is in the pro file I put "RC_ICONS = logo7.ico".</p>
  
  <p>When I install the program on my computer (Win8), it works well. The desktop shortcut's icon shows my logo perfectly and full size. However, when I install the program on another computer (Win10), the desktop shortcut's icon is not full size. Even if I CTRL-scroll on the desktop to change the icon size, this icon remains the same size.</p>
  
  <p>Here is an example of two desktop icons (one full and the other one that does not scale).

  <p>Is there something special I should do with my icon (I tried icon sizes of 128x128 to 512x512) so that its full screen ?
  Or is it something to do in Qt ?</p>
  
  <p>Thank you so much !</p>
