We have a couple of similar bugs describing the same problem.
While we are looking for a proper solution to fix this issue.
Meanwhile, there are at least two workarounds that you

Would it please be possible to share the workaround, since the bugzilla bug is limited to a group?

You need to run "netsh dump > filename.txt" command from the elevated cmd prompt before un-install
and restore the settings with " netsh -f filename.txt" command after installing the new virtio-win package.

I also need to mention that recently we added a new custom action to virtio-win installer which designed to save and restore netkvm network settings automatically virtio-win/virtio-win-guest-tools-installer@ea0643f

Best,
Vadim.

I have same issue, when i open a c# program in server2016 vm, we lose all network connect.

@CHN-STUDENT
Not sure that your issue somehow related to this case.

This particular case is about loosing network interface settings while updating virtio-win package.
The problem has been solved with virtio-win/virtio-win-guest-tools-installer#57
and should work fine on the latest virtio-win releases.

Best,
Vadim.
