Share internet connection with 'remote' computer
This might seem like a strange idea, but I've come across this situation multiple times now.
The remote computers which I manage are in a network without internet connection (by purpose). I use Teamviewer to connect with the 'remote' computer via the local network. Every now and then I would like to update the remote computer (Windows Update), but this is not possible because the internet connection is not available. If I could (temporarily) share my own internet connection with the remote computer, it would be possible to run Windows Updates on the remote computer.
I know there is an option in Windows to share your internet connection (e.g. wifi) to a local connection (e.g. LAN), but this feature requires changes to the network settings of the remote computer (which is not an option in my case).
