Just to follow along on this part, I've pulled the CAT-5 from my BBB.

WHY a screen grab? You are using a text console, aren't you -- just
select/copy/paste the TEXT...

Pinging the host computer works, even without a gateway setting (since
192.168.7.1 and 192.168.7.2 are the same network, and likely it is presumed
that all hosts on that network can be reached using the adapter [usb0] that
is itself on the network).
If that simple step is failing, you might have to check whatever
firewall you have running on Windows.
NEXT action I tried was opening the Windows "Network Connections"
control panel. BRIDGING "Ethernet" (remember -- My systems are normally
cable connection) and "Ethernet 2" (the RNDIS gadget) is not the correct
action, as it kills the Internet access on "Ethernet" (and there is an
advisory that one cannot bridge an ICS adapter).
So... remove bridge, open "Ethernet" and enable Sharing, specifying
"Ethernet 2" as the private network side.
With ICS active, Windows assigned 192.168.137.1 to the RNDIS adapter! I
just edited that to use a manual IP address 192.168.7.1, length 24, and
gateway is set to my router (192.168.1.1). (I used the "WiFi" section as
that was the control panel type I had open)

SSH back into the BBB at 192.168.7.2.
Lastly, I added a gateway on the BBB...

Okay, I didn't expect that layer to change, as that is just BBB to host
level.

{Now to see how difficult it is to undo all this}
