# Windows – “Generic failure” when creating virtual switch in Hyper-V Manager

hyper-vwindows 10

I have installed Hyper-V from Windows Features but when i open Hyper-V Manager and try to create a Virtual Switch i get this error (NONAME is the computer name):

I read over the internet for solution but I don't find anything that solve my problem. I have checked at the Ethernet properties option "Hyper-V Extensible Virtual Switch" but error still show up. Also I tried to uninstall and install again the Hyper-V Manager but also nothing happened.I have Windows 10 Pro and is clean installation. Any ideas what to do?
