title: Update Visual Studio 2017 from Visual Studio 2015.3 and 2017 rc
body: <p>Good morning,
  I have installed in my PC (Windows 10) Visual Studio 2015.3 and Visual Studio 2017 RC, both of them with a lot of things installed on.
  Now, that Visual Studio 2017 is finally out, I want to have only and don't have Visual Studio 2017 RC or the "old" Visual Studio 2015.
  I search over <a href="https://docs.microsoft.com/en-us/visualstudio/install/create-an-offline-installation-of-visual-studio" rel="noreferrer">internet</a> and I find how to have an off-line installation of Visual Studio 2017. Now I don't know which is the best solution between:</p>
  
  <ol>
  <li>Uninstall All plugin like resharper or so on, restart, uninstall Visual Studio 2017 RC, Restart, Uninstall Visual Studio 2015.3, restart, install Visual Studio 2017, install all plugin</li>
  <li>Install Visual Studio 2017, update all plugin, uninstall Visual Studio 2017 rc, uninstall Visual Studio 2015.3</li>
  </ol>
  
  <p>Or other...is there someone that have a simil issue?</p>
  
  <p>Thanks</p>
