title: Lost Network Interface Virtualbox on Win7
body: <p>Yesterday I have installed Virtualbox on my win7 notebook and i have seen, that VB have install a network interface on the win7 network properties.</p>
  
  <p>After installing Ubuntu guest on a new VB-instance, ubuntu cannot connect to the internet. Later into the night i have read somewhere that i should deactivate the network-interface and re-activate it. </p>
  
  <p>So, i have deactivate this network-interface on win7 and after that, i have lost this and cannot re-activate it. The VB-Guest cannot connect now over bridget and so on. </p>
  
  <p>How i get the network interface back into win7 for working the vb guest over bridge?</p>
