title: Windows triggering on custom URL scheme
body: <p>I've created a custom URL scheme on my Windows 10 machine. 
  I trigger the URL scheme to start my application which is connected the the scheme.</p>
  
  <p>myapp:name="Test"</p>
  
  <p>myapp is the custom scheme connected to MytestURIApp.exe.
  It seems to work in launching MytestURIApp.exe.</p>
  
  <p>I have 2 questions here.  If MytestURIApp.exe is not running already the entry point when triggering the URL scheme should be the main(...)  function where I can catch the URI sent ?</p>
  
  <p>If the application is already running how do I register an entry point from here?
  If already running I want to be able to check that the URI sent is a valid one and then do some stuff.</p>
  
  <p>Thanks</p>
