Bridged networking not working in Virtualbox under Windows 10

Question

I just upgraded my laptop from Windows 7 to Windows 10 and found that I am unable to start Virtualbox VMs configured with a bridged adapter.

See the configuration below:

Answer 1

Install "vbox-ssl-cacertificate.crt" certificate from %userprofile%\\.virtualbox\ and then reboot. If you don't have .virtualbox folder - launch "Oracle VM VirtualBox" once and this folder will appear.

I had this issue not only on my machine but on many hosts, and this certificate fixed the issue. I figured it out by chance, because nowhere said about this certificate -_-
