Today is an easy one. I have had several questions about Network Adapters and specifically vEthernet adapters around 1803 and 1903. These are follow on questions to everyones favorite: Where did my Virtual Machines go after I did an inplace upgrade. vEthernet is created exclusively for HyperV on a windows 10 devices. Two default ones are now created.
vEthernet (Default Switch)
This was first added around Windows 10 1803. It is created by default for HyperV when that optional extra is enabled.
- Open a command prompt – Winkey+R
- (upper left) Turn Windows features on or off
You can see the list of switches in your Network & Internet Settings or here:
What is it good for?
Great question? It is the default option for any newly created virtual machine as of about 1803. Really useful for Linux variants you pick up from the Microsoft Store. Can I do anything else with it? Not really without causing an unpredictable headache. Generally speaking I create a NAT and private virtual switches if I am doing anything beyond trying a new distro or I want devices to work together.
Same idea as Default Switch with isolation. This one is created by Windows Sandbox being enabled. I really like the idea of Sandbox but until I can do further configurations for testing I only use it for one off URL or Application testing – https://techcommunity.microsoft.com/t5/ITOps-Talk/How-to-configure-Windows-Sandbox/m-p/650418
You turned on features that use the network in Windows 10. Good news Microsoft has your back. No they are NOT a virus or hack as you see on some of the scare monger websites.
