[QUOTE="TairikuOkami, post: 798716, member: 61892"] As far as I know, WU requires only svchost, but lately I allow all outbound, so maybe I have missed something. :unsure: [CODE]netsh advfirewall firewall add rule name="Svchost DNS" dir=out action=allow protocol=UDP remoteport=53 program="%WINDIR%\System32\svchost.exe" netsh advfirewall firewall add rule name="Svchost TCP" dir=out action=allow protocol=TCP remoteport=80,443 program="%WINDIR%\System32\svchost.exe"[/CODE] I use [URL="https://www.nirsoft.net/utils/live_tcp_udp_watch.html"]LiveTcpUdpWatch[/URL] to find out network traffic, since it logs traffic. Like, I could not figure out, how to get [URL="https://www.sordum.org/9203/update-time-v1-2/"]Update Time v1.2[/URL] working, because it makes the connection so fast, that it only blinks in network monitors like currports. Then I found this little gem from nirsoft. [ATTACH alt="208752"]208752[/ATTACH] People, who tried it, ended in a psychiatric ward. Just setting up loopback can be changeling and do not even get me started on LAN network. :emoji_expressionless: [/QUOTE]
