title: Visual Studio 2017 installer extremely slow
body: <p>I tried to install the latest VS 2017 Update yesterday and since then I cannot get it to finish this. </p>
  
  <p>This worked pretty fine in the last months and stopped working yesterday. </p>
  
  <p>I already tried to do the following:</p>
  
  <ul>
  <li>Uninstall VS 2017</li>
  <li>Remove folder <code>%PROGRAMFILESx86%\Microsoft Visual Studio\2017</code></li>
  <li>Remove folder <code>%PROGRAMDATA%\Microsoft\Visual Studio</code></li>
  <li>Restart machine</li>
  </ul>
  
  <p>I have a 50 MBit/s download rate and all other apps are working just fine. If I look into the logs I can see failed downloads when I abort the instalation. When I pick one of the URLs there and just download the vsix directly via the browser it just works.</p>
  
  <p>Is there any caching or network setting that might be useful in this case?</p>
  
  <p><strong>UPDATE</strong>
  I have tried 2 downloads (WLAN) from MS servers right now:</p>

  <p>Has MS issues on certain download servers maybe and what to do or whom to tell in those cases?</p>
