title: How to distribute a GTK+ application on Windows?
body: <p>I have installed GTK+ (specifically GTK3) via MSYS and MinGW on Windows. I now want to copy the GTK+ dlls to my application directory so that it can be run on a computer without a global GTK+ installation. Which dlls are required for GTK+ to operate?</p>
  
  <p><strong>EDIT:</strong> The GTK+ documentation now contains <a href="https://www.gtk.org/docs/installations/windows/#building-and-distributing-your-application" rel="noreferrer">instructions</a> for distributing the required icons and themes on Windows. (Although it doesn’t have instructions for distributing the relevant DLL files — for that see the answers below.)</p>
