I was trying to restore my hyper-v virtual switch network. it was working fine before the last windows 10 Pro update. I was able to bind the External Virtual Switch to my Wireless NIC which is AC3165. however, after windows updates. my network settings was not working. when I tried to restore the configuration, I got errors like "Error applying Virtual Switch Properties changes failed whiled adding virtual Ethernet switch connection (0x80070490) " and after I use the Microsoft resolution to run "MicrosoftEasyFix20159.mini.diagcab", then try to do the same setup for the External Virtual Switch, it give me the error like " Error applying Virtual Switch Properties changes. The operation failed because the object was not found. " I tired. 1. "netcfg -d" 2. uninstall and reinstall the "Hypver-v" 3. use Microsofteasyfix20159.mini.diagcab none of these above worked out for me. please help and give me some clue where I should tune to make it work again.
