A mysterious piece of “under development” code is playing havoc with the Windows Firewall after the latest preview update for Windows 11 24H2.<\/p>\n

The problem manifests as an error in the Event Viewer for Windows Firewall With Advanced Security and can occur following the installation of the June 2025 Windows non-security preview update<\/a>.<\/p>\n

In the latest entry in Windows 11 24H2’s hall of shame \u2013 aka Microsoft’s Release Health Dashboard<\/a> \u2013 the company explained: “The event appears as ‘Config Read Failed’ with message ‘More data is available.’<\/p>\n

“Although this event is logged in Event Viewer every time the device is restarted, they do not reflect an issue with Windows Firewall, and can be disregarded.”<\/p>\n

So, there you go. Something in the update has upset the Windows Firewall, but users should ignore it and continue with their day.<\/p>\n

The problem is “related to a feature that is currently under development and not fully implemented,” according to Microsoft. It also stated that the Windows Firewall “is expected to function normally,” which is reassuring, and “there is no impact to Windows processes associated to [sic] this event.”<\/p>\n

The Event Log is also used to monitor the health of Windows devices, so spurious errors \u2013 even ones that can be ignored \u2013 will be a headache.<\/p>\n
