    Hyper-V virtual switches difference?


    I made a new external switch in Hyper-V, and the screenshot below is what I have now:

    Hyper-V virtual switches difference?-switch.png

    First 3 adapters from screenshot are as follows:

    1. Physical realtek adapter
    2. Default (non removable) virtual switch
    3. vEthernet is the external switch I made

    BUT, what is this 4th switch? (the one highlighted in the image above)

    My question is what's the purpose of this 4th one here called:
    vEthernet (vEthernet (Exte)

    If I disable it, nothing bad happens, my network works on both host and guest systems.

    Btw. I don't know if the external switch made this one, it was present there since long time ago because it's not the first time I made external switch.

    You can end up with loads of these each time you set up a new switch or new vm. I just delete them from Device Manager.

    Nothing to worry about.

    I saw people complain about this somewhere, but, I did reinstall Hyper-V at least twice, and also recreated switches, but never had issue of switches being spammed like some people do.

    This one is the only one that was made, I never deleted anything.

    However I would still like to know why it was made in the first place? something is telling me it's not a bug but some temporary functionality.
