title: Failed to open/create the internal network Vagrant on Windows10
body: <p>I upgraded my Windows 10 to the last update yesterday and now, when I launch  <code>vagrant up</code> command, I get this error :</p>
  
  <pre><code>==&gt; default: Booting VM...
  ==&gt; default: Waiting for machine to boot. This may take a few minutes...
  The guest machine entered an invalid state while waiting for it
  to boot. Valid states are 'starting, running'. The machine is in the
  'poweroff' state. Please verify everything is configured
  properly and try again.
  
  If the provider you're using has a GUI that comes with it,
  it is often helpful to open that and watch the machine, since the
  GUI often has more helpful error messages than Vagrant can retrieve.
  For example, if you're using VirtualBox, run `vagrant up` while the
  VirtualBox GUI is open.
  
  The primary issue for this error is that the provider you're using
  is not properly configured. This is very rarely a Vagrant issue.
  </code></pre>
  
  <p>When I try with GUI I have this error :</p>
  
  <pre><code>Failed to open/create the internal network 'HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter' (VERR_INTNET_FLT_IF_NOT_FOUND).
  Failed to attach the network LUN (VERR_INTNET_FLT_IF_NOT_FOUND).
  </code></pre>
  
  <p>I have re-installed VirtualBox 5.0.10 and the extension pack,
  reconfigured Host-Only Ethernet Adapter, but always the same error...</p>
  
  <p>Any ideas?</p>
