So I automatically received the Windows 10 anniversary update this afternoon (against both my will and my explicit no-update settings) on my work computer. When I logged back in, all of my network adapters except one had disappeared (I previously had a virtual switch set up via Hyper-V to allow emulated devices to have internet access).
When I try to assign an IP address to the remaining NIC, I get this delightful message:
The IP address you have entered for this network adapter is already assigned to another adapter 'Hyper-V Virtual Ethernet Adapter' on this computer. If the same address is assigned to both adapters and the both become active, only one of them will use this address. This may result in incorrect system configuration.
It appears that the update unhelpfully uninstalled hyper-v manager, but did it in such a way that the ghosts of networks past still haunt me.
When looking in the Device Manager, the listed adapter does not appear. Having device manager 'Show hidden devices' does not make it appear either (even if I run the 'set devmgr_show_nonpresent_devices=1' command).
Ipconfig doens't list the device either.
I thought maybe if I re-installed Hyper-V I'd be able to manage it from there, but having done that and rebooted, the adapter isn't there either.
I tried removing it in Powershell via 'remove-vmswitch' but that failed saying it couldn't find such an adapter.
How can I remove all traces of this apparently invisible adapter so that my NIC starts working properly again?
