title: How do I run the Visual Studio (2017) Installer?
body: <p>It's probably really obvious once you know the answer, but I can't find it anywhere.</p>
  
  <p>I'm not talking about <em>making</em> an installer, I'm talking about running the installer that lets me modify which features of Visual Studio 2017 are installed.</p>
  
  <p>The main screen looks like this:</p>

  <p>the screen I need is this one:</p>

  <p>In Visual Studio 2017, there is a menu entry for "Extensions and Updates" under the Tool menu that doesn't take me to this application.
  There is also a "NuGet Package Manager" which isn't even close.</p>
  
  <p>In my Windows 10 start menu, I see Visual Studio 2017 itself, and a folder named "Visual Studio 2017" that contains a couple of command prompts and a "Debuggable Package Manager".</p>
  
  <p>In the Control Panel - Programs and Features, I see Microsoft Visual Studio 2017 but right-click only gives me "Uninstall".</p>
