Rename the "Block QUIC" checkbox
The "block google QUIC" checkbox does not actually block QUIC, as it says, but instead blocks all UDP on port 80 and 443. 443 UDP is not always QUIC! This is misleading, and should be renamed to "Block UDP 80 and 443 (like Google QUIC)".
Skype for Business/Teams use UDP on port 443, this setting forces the apps to use TCP and may causes quality issues.
