“Use the Internet Connections Troubleshooter” LOL! Of no value whatsoever because there’s no ‘network cable’ to ‘unplug’.
I’m sure that the other steps might help some people…but they didn’t help me.
The basic problem is one of OpenVPN’s apparent inability to write (or commission) a TAP-Windows Adapter V9 that is properly compatible with Windows 10.
As far as I can see, this page is basically an ad for paid software – funnily enough, the last option. Greed, the ultimate motivator.

For the instructions of restart and reinstall TAP adaptors (#2 and #4), the TAP adaptor doesn’t even show up in the two screen shots (exactly what I see in my PC), how do you disable/uninstall it if it doesn’t even show up?
