For months I've seen an 'unidentified network' everywhere in my Win10 GUI. I found
https://github.com/nmap/nmap/issues/653
https://github.com/nmap/npcap/commit/a9b7f9e
Which seemed to say the new Npcap version should not appear in my Wi-Fi selector or Network Settings as an unidentified network (where it says 'npcap loopback adapter doesn't have a valid ip configuration').

--> With default install of new npcap-0.93.exe version - it still appears...
--> Install with support loopback unchecked - it still appears. Even after a restart.
With 'Npcap Loopback Adapter' disabled in Network Connections, it doesn't appear all over, just there.

Loopback Adapter Windows 10
Trying the uninstall procedure shown above here, there is one 'Npcap Loopback Adapter', but inside that it is all Microsoft, version 10.0.14393.0 (rs1_release.160715-1616), raspptp.sys - is that Npcap?
The only 'events' are from 8/8/2016 10:22:33 AM (the Anniversary Update), device configured (netrasa.inf), device started (Pptp Miniport). No sign of all the installs and supposed uninstalls of Npcap since then! Cycling through all the 'Details', the only hints of Npcap are the 'Display Name' and 'Friendly Name'.
I'm a bit afraid to uninstall this - it doesn't look to me like Npcap... But how can it have your name? Clues would be very welcome!
Configuring the Loopback Adapter on Microsoft Windows One of the most missed configuration issue when installing Oracle Database on Windows systems is failure to configure the Loopback adapter prior to installing the software on DHCP clients. After searching on the Net I can find nothing positive or useful about the Npcap Loopback Adapter. Seems like something designed for Microsoft's benefit that provided nothing for its average user. So has anybody else had problems with this thing and more importantly is it safe to Disable and or even Un-install.
When you install a loopback adapter, the loopback adapter assigns a local IP address for your computer.
After the loopback adapter is installed, there are at least two network adapters on your computer: your own network adapter and the loopback adapter. To run Oracle Database on Windows, set the loopback adapter as the primary adapter.
You can change the bind order for the adapters without reinstalling the loopback adapter. The bind order of the adapters to the protocol indicates the order in which the adapters are used. When the loopback adapter is used first for the TCP/IP protocol, all programs that access TCP/IP first probe the loopback adapter. The local address is used for tools, such as Oracle Enterprise Manager. Any other applications that use a different Ethernet segment are routed to the network card.
A loopback adapter is required if:
- You are installing on a non-networked computer and plan to connect the computer to a network after installation.
- Checking if a Loopback Adapter is Installed on Your Computer
To check if a loopback adapter is installed on your computer, run theipconfig /all
