Install VcXsrv https://sourceforge.net/projects/vcxsrv/

Close everything and go to Windows Firewall with Advanced Security -> Inbound rules and delete every rule you see for Vcxsvr.exe. After that the first time you launch Vcxsvr make sure you Allow access for Private AND Public networks.

Search for VcXsrv entries (there should be two) and disable all found.
