title: How to update Visual Studio 2017 using command line?
body: <p>I'd like to automatically update my Visual Studio 2017 installation from a script (running this script at session login).</p>
  
  <p><code>vs_installer</code> shows a bunch of command line arguments (using <code>/?</code>). So I tried :</p>
  
  <p><code>&amp; "C:\Program Files (x86)\Microsoft Visual Studio\Installer\vs_installer.exe" update --passive --norestart</code></p>
  
  <p>However, nothing happens. I see the process in the task manager for a few seconds, but the product is not updated.</p>
  
  <p>How to update my VS installation ?
  Is is possible to handle the installer update ?</p>
  
  <p>PS: if possible, I'd to have a passive update, not an invisible update. I'd prefer seeing the product being updated to avoid launching a new instance while the update is in progress.</p>
