Microsoft successfully addresses Windows 11 Firewall issue following two earlier unsuccessful attempts
================================================================================
In a recent development, Windows 11 users on version 24H2 have been encountering a persistent, false critical error in Event Viewer related to Windows Firewall with Advanced Security, logged as Event ID 2042. This error, characterised by a "Config Read Failed" message with the additional information "More data is available," first appeared with the June 2025 optional update (KB5060829) and was mistakenly claimed as fixed in the subsequent July 2025 cumulative update KB5062553.
Initially, Microsoft claimed that the issue had been resolved. However, the error persisted and has gotten worse, now affecting a larger number of users. This information was discovered by Windows Latest and later reported by Forbes.
Microsoft has officially acknowledged this ongoing issue and apologised for the incorrect claim of resolution. The company has clarified that the firewall itself is fully functional and the error is purely a harmless bug in the event logging system, with no impact on security or network filtering. Microsoft advises users to safely ignore these error entries or filter out Event ID 2042 from their event logs to reduce noise.
A fix is anticipated in an upcoming cumulative update planned for release shortly after July 2025. Microsoft has released a newer preview cumulative update KB5062660 in July 2025, which reportedly resolves the problem for some users, but confirmation about universal resolution is still pending. Until that update is broadly deployed, the error will persist.
It's worth noting that Microsoft attributes the issue to a feature currently in development and not fully implemented. The error seemed more prevalent and widespread, prompting an apology from Microsoft.
For users experiencing this issue, the best workaround is to ignore the errors or filter them out from logs. It's important to remember that this error does not pose a major concern for system failures, but it can be annoying for experienced users, especially while monitoring particular system processes.
This reflects the current known status and recommended handling of the persistent Windows Firewall with Advanced Security error in Windows 11 24H2 as of July 2025. The error was initially reported by Windows Latest and later reported by Forbes, and Microsoft has detailed the issue in the "known issues" section of the Release Health Dashboard.
