• Choose the problematic device in Network Adapters (NDIS based device)
• Right click on it and choose Update Driver Software...
• Click Browse my computer for driver software
• Click Let me pick from a list of device drivers
• Uncheck the box Show compatible hardware For the manufacturer, choose Microsoft Now you will have two options:
  • Remote NDIS based Internet Sharing Device
  • Remote NDIS Compatible Device chose the second one and it solved the problem
