Ethernet network adpter failing on Thinkpad basic docking under Windows 10

[SuperGraham]

I had the same problem when the Windows 10 Anniversary Edition update was installed. My HP USB Giga Ethernet was replace by the DisplayLink Network Adapter NCM driver which failed with a code 39 error. So I disabled real-time protection, which disabled Windows Defender, uninstalled the DisplayLink Graphics Driver software and the failing DisplayLink Network Adapter NCM device from Device Manager, then reinstalled the DisplayLink Graphics Driver software. At which point the HP USB Giga Ethernet device reappeared. Thanks Alban for a successful fix.
