Windows 11, equipped with its own robust Windows Firewall, is designed to safeguard users against unauthorized access, whether from the internet or local networks. This essential tool diligently monitors both incoming and outgoing network traffic, effectively blocking connections that it identifies as potentially harmful.
Recent Update Issues
However, a recent preview update for Windows 11 version 24H2 has unveiled a rather unexpected hiccup concerning the Windows Firewall with Advanced Security. Microsoft has acknowledged this issue, which is detailed in the Release Health Dashboard under the “known issues” section. The reported problem manifests as a security event log error related to the firewall.
The specific error is characterized by a “Config Read Failed” message, accompanied by the note “More data is available.” This has raised concerns among users, prompting Microsoft to recommend the installation of the latest updates to address this and other issues.
To resolve the inconvenience, users are encouraged to install the July 2025 Windows security update or any subsequent patches. These updates not only rectify the firewall error but also introduce various improvements, ensuring a smoother user experience overall.
As always, staying updated with the latest patches is crucial for maintaining the integrity and performance of your system.
