While accessing Virtual Switch Manager, I receive a "generic failure" .

I have followed instructions on removing Hyper-V and reinstalling Hyper-V. Still unable to access virtual switch manager.

Also, followed instructions on deleting the registery key

HKLM\SYSTEM\CurrentControlSet\Services\VMSMP\Parameters\SwitchList

I do not have the "switchlist" parameters.

Finally, when I go to network connections, I see a Default Switch listed that has unprintable characters. I tried deleting that using powershell but received a generic error.

Any help or guidance to allow me to run Hyper-V will be appreciated.

    Hi Jai,

    Thanks for your post. We have encountered similar issue and resolved by following methods.

    1. Uninstall and reinstall the network adapter.

    After a Windows 10 update, and re-installing the network adapter, it might take effect.  

    1. If not, executing the following command in a PowerShell console to create new virtual network switch:

    New-VMSwitch VMSwitch -NetAdapterName Ethernet

    This will rebuild the network switch configuration so after this the Virtual Switch Manager started successfully and you can able to use it to remove and create virtual switches.

    Best Regards,

    Ian Xue
