Is there a way to enabled "Internet Connection Sharing" on Windows 7 (or higher) using command line? Perhaps using "netsh" or a similar command?

I think this question should be on superuser.com. And it is there: https://superuser.com/questions/470319/how-to-enable-internet-connection-sharing-using-command-line.

If you are interested how to do it programmatically – here is the source code at GitHub: https://github.com/utapyngo/icsmanager.

To manage "Internet Connection Sharing" under Win7 you must exec net start SharedAccess or net stop SharedAccess.

You can also configure the service using sc config SharedAccess start= disabled or sc config SharedAccess start= auto and some other. Run sc config to know other options for the "start= ". The space between start=OPTION is mandatory.

In my case, I want to use VirtualBox Host-only Adapter alone for two-way communication and Internet sharing, I use Powershell to achieve that.

  1. Start cmd as admin and type the following netsh wlan set hostednetwork mode=allow ssid=networkname key=networkpassword

  2. Press enter then type NETSH WLAN start hostednetwork

  3. press enter again.

remember to replace the networkname and networkpassword with your preferred names and password respectively

    Creating a hosted network is a diffrent step from sharing another interface's connectivity within this network (ICS) – mveroone May 20 '18 at 08:39
