config read failed

The 'config read failed' error on Windows 11 is associated with Event ID 2042 in the Windows Firewall with Advanced Security. Users have reported this error appearing in the Event Viewer after installing the June 2025 non-security preview update KB5060829. The error message 'More data is available' logs each time the system restarts. Microsoft has clarified that this error does not indicate a firewall malfunction; the firewall continues to enforce rules and filter traffic normally. Discussions on WindowsForum.com cover the cause, impact, and official guidance for this issue, helping users understand that the error is a logging artifact rather than a security threat.
