PROBLEM SOLVED!
The Windows Updates issues are due to the old COMODO Firewall 2024 version which, for some reason, is blocking Windows Updates on Windows 11 24H2. Even if this is not an intended behavior for the 2024 version, updating to the 2025 would fix the issue. I have upgraded and updates now work regularly.
Solution:
- Uninstall COMODO Firewall/Internet Security
- Install CIS Premium 2025 (free). If you want only the firewall, you have to select “options” (the customized installation) and then under “components” make sure that only COMODO Firewall is flagged. Install it from here: New Version 12.3.4.8162 Available for Comodo Internet Security 2025
For COMODO team, to solve:
- Push the 2025 update to all machines where COMODO Firewall 2024 / Internet Security 2024 is installed (I use the firewall on 2 machines and both were saying COMODO was up-to-date, but it was not)
- As already said, update the COMODO Firewall installer on this website: https://personalfirewall.comodo.com/ and all 2024 installers on your website
