In recent weeks, Windows 11 users have encountered a persistent issue involving the Windows Firewall with Advanced Security. Following the installation of the June 2025 non-security preview update (KB5060829), many reported recurring error logs in the Event Viewer, specifically Event ID 2042 labeled "Config Read Failed" with the message "More data is available." This error appears each time the system restarts, leading to confusion and concern among users.
Microsoft initially addressed the issue by advising users to disregard these error messages, stating that they are related to a feature still under development and do not impact the firewall's functionality or system processes. The company assured users that Windows Firewall continues to operate normally and that no action is required to resolve the error event. This guidance was documented in the Windows Release Health dashboard.
On July 8, 2025, Microsoft released the July 2025 Windows security update (KB5062553) and updated the Windows Release Health dashboard to indicate that the firewall error issue had been resolved. However, users quickly reported that the error persisted even after applying the update. Upon further investigation, Microsoft acknowledged that the update to "Resolved" status was made in error and reverted the status back to "Confirmed." The company stated that it is still working on a proper fix, with an expected resolution in the coming weeks.
This situation highlights the challenges associated with rolling out new features and updates in complex operating systems like Windows 11. While the error messages do not indicate a functional problem with the firewall, they can cause unnecessary alarm and confusion among users. Microsoft's transparent communication and prompt acknowledgment of the issue are commendable, but the incident underscores the importance of thorough testing and clear communication in software development and deployment.
Users are advised to monitor official Microsoft channels for updates on this issue and to apply forthcoming patches as they become available to ensure the stability and security of their systems.
