title: Start a Windows Run command in Python (Browser protocol)
body: <p>I want to open a specific application on my computer which can be done by running </p>
  
  <pre><code>application://open/window/
  </code></pre>
  
  <p>in Windows from the Windows Run-command (Start -> Run, resp. Windows-key + R).</p>
  
  <p>How can I run this from Python?</p>
  
  <p>The following does <strong>not</strong> work:</p>
  
  <pre><code>import os
  os.system("application://open/window/")
  </code></pre>
  
  <p>since this will run the command from the Windows command-line, which does not know what <code>application:</code> is.</p>
