Hello,
till today i was using Comodo Free Firewall for many Years on Windows.
But a few days ago Microsoft rolled out his big update 20H2. This Update failed always around 73% with a blue screen of death. After a long time testing, analyzing dump files, the reason was found. It was (verified) the Comodo free Firewall.
This as information for you, to fix this issue and maybe make the Comodo Firewall ready for the next windows10 Updates.
For me, I use now the integrated firewall with a small control panel.
Best regards.
