    Can you see them in Virtual Switch Manager? If not, check if they can be seen in elevated PowerShell with cmdlet Get-VMSwitch. If shown, delete with Remove-VMSwitch -Name SwitchName.

    That did not work but the answer was simple - just uninstall them from device manager.

    I am having an issue since 17134.1 whereby if I use external switch, my download speeds on host are massively reduced. Others have been getting this issue.

    If you connect using the default switch, all is fine but then the NAT prevents you RDPing to VM.

    The solution allegedly is to create an internal switch, and from network and sharing, give the internal switch a static IP address, and then bridge the Host wifi adaptor to the internal switch.

    I have tried this, and it immediately disables Internet on the Host.

    Does anybody have any idea how to fix this?

    Hi there

    Open port 3389 on the VM ensure firewalls OK

    say NAT addr is 10.0.0.1

    then in your RDP this should work 10.0.0.1:3389

    Cheers

    Actually, once I deleted all the old switches and recreated the internal switch, it now works fine!

    LOL!

    It can sometimes be a mess when working with network adapters and Hyper-V switches in Windows.

    So I just tested everything on my end, and all works exactly as it should, once I enabled access for RDP on my VMs.

    Glad you got it sorted out. :)

    I spoke too soon. I got the switches and RDP working but I still get a massive download reduction (as I did using an external switch). Oddly upload is not affected

    Picture on left is using wifi adaptor direct, right is via a virtual network bridge

    And here it is with wifi NOT Bridged but an eternal switch, now using the vEthernet adaptor.

    Something is clearly screwed up.

    Yep, I get 1/10 of speed on my VM-Host (30Mbit), while on the VM I get full speed (350Mbit). HAHAHA!
