    Can't install Loopback Adapter after last windows 10 update

    Hello Kevin,

    If you're having issue installing MS KM-TEST Loopback Adapter, we suggest performing the manual methodas explained in the steps provided below:

    • Click the Start Menu. In the search box type “hdwwiz” and then click the hdwwize.exe program link.
    • Now the Add Hardware wizard should be open. Click next through the first page, and then on the second select install the hardware that I manually select from a list (Advanced). Click next to continue.
    • Scroll down the list and Select Network Adapters then Click Next.
    • Give the next window a moment to load, and then Click Microsoft and Select Microsoft KM test Loopback Adapter.

    Now the Microsoft KM test Loopback Adapter should be installed and it will show up in your network connections window.

    Let us know if that worked out for you.
