title: Detecting custom url protocol handler using javascript in windows 10 Edge Browser
body: <p>In our web application we need to find out if a <strong>Custom URL Protocol Handler</strong> is registered or not in windows 10 machine using javascript with <strong>Windows 10 EDGE Browser</strong>.</p>
  
  <p>If the <strong>Custom URL Protocol Handler</strong> is not registered in the windows 10 machine we will ask the user to download our desktop standalone app.
  If registered we will start our desktop standalone app using the registered <strong>Custom URL Protocol Handler</strong>.</p>
  
  <p>Since EDGE is a new browser the solutions provided by other users in the internet are not working.</p>
  
  <p>Links I referred that are not working for me in EDGE browser:</p>
