Cannot remove Hyper-V Virtual Ethernet Adapter

Hello,

I am having a networking problem with Hyper-V on Windows 10 pro. I installed Hyper-V in order to create some test VMs, but could get the networking to function properly. I removed Hyper-V, but there is still a virtual Ethernet adapter stuck somewhere, and I can't find it. Not listed in Network connections or Device manager. If I try to change the static IP of the physical adapter, I get the following error: "The IP address 10.2.2. 100 that you have entered for this network adapter is already assigned to another adapter 'Hyper-V Virtual Ethernet Adapter' on this computer". I would really like to get rid of that so that I can take another run at Hyper-V on this machine.

Welcome to our new Microsoft Q&A Platform.

Please refer to the following steps:

1.Run the command of s*et devmgr_show_nonpresent_devices=1* and press ENTER.

2.In Device Manager, click VIEW then SHOW HIDDEN DEVICES.

3.Expand NETWORK ADAPTORS,Check if there are any grayed out NICs and select UNINSTALL.

If it still doesn't work, please check if the following link is helpful:

Cannot remove Hyper-V Virtual Ethernet Adapter - SOLVED

After doing a lot of investigation of this problem I have finally found the solution at this link:
https://social.microsoft.com/Forums/en-US/d443bc7f-4cf4-4a8a-9ae3-4fd359c37849/windows-sandbox-on-win10-2004-now-creates-vethernet-interface-for-every-physical-nic?forum=win10itprovirt

The reason you are getting a Hyper-V Virtual Ethernet Adapter popping up is due to Windows Sandbox.
Windows Sandbox on Win10 2004 now creates a vEthernet interface for every physical NIC.

Uninstalling the Sandbox in Control Panel -> Programs and Features -> Turn Windows features on or off, and rebooting, removes these switches. If you wish to keep Windows Sandbox, you will need to also keep the switches.

I unticked Windows Sandbox and rebooted. Now Hyper-V Virtual Ethernet Adapter has disappeared. Also the HV Host Service, which was previously running, has now stopped. All good, and I my corporate intranet is now happy again.

I tried removing almost everything in Windows Features on Windows 10 Pro to get rid of the Hyper-V Virtual Ethernet Adapter in Network Connections, but that still didn't work, even with everything related to Hyper-V removed... until I stumbled upon this little thing in Services called "HV Host Service", which has the description of "Provides an interface for the Hyper-V hypervisor to provide per-partition performance counters to the host operating system."

Once I disabled this service, Hyper-V Virtual Ethernet Adapter was immediately gone, and has been gone since I disabled that service.

There are three services that create vEthernet switches automatically amongst the default Windows features that I know of.
- Hyper-V
- Windows Sandbox
- Windows Subsytem for Linux

You seem to have Windows Sandbox still enabled, disable that and your vEthernet will go away without manually disabling the HV host service, which is simply just managing the network connections for the above mentioned features...

For anyone finding this thread like I did, I had already disabled the Hyper-V & Windows Sandbox features, but I had forgotten about the Windows Subsystem for Linux. There also appears to be some issue with my network connection and my laptop drivers (HP), so I wanted to leave the virtualization features disabled for a few days and see if that fixes it. (And then go looking for a solution to enabling Hyper-V/WSL without losing connection, if that is indeed the issue...)

you're the man!!!
i've suffered reading all the solutions, nothing worked at all "PowerShell-Windows feautures included SanBox and any dusty Box!!" everything.... vEthernet still there!!

when i've seen you're talking about the services, i've entered and disabled any service with HV letters, it was around 9 services or something, then i've restarted and the vEthernet annoying thing gone and for ever, it cost me 2 days delay in my work due to undetected network devices to configure!!

Dandy Thanks!!

Awesome! Was having a conflict with MS Teams that would crater my ethernet. Had to restart just to turn off the service but fingers-crossed! Thanks
