- The "Windows Firewall With Advanced Security 2042 None" error is harmless and only affects the event log.
- Microsoft wrongly claimed the bug was fixed in the July update, when in fact it rolled out to more users.
- The company has apologized and promises a permanent solution in future updates.
- Users can ignore the related warnings, as the Firewall is still working correctly.
During the last weeks, Microsoft has been at the center of controversy over a flaw in the Windows 11 Firewall. which has generated confusion and concern among its users. It all started after the arrival of an optional update in June and, subsequently, the cumulative patch of July (KB5062553), where it appeared in the Events viewer a message baptized as “Windows Firewall With Advanced Security 2042 None”Many users, upon seeing this critical warning, thought they were facing a real security problem, but The reality has turned out to be less alarming than it seemed..
The origin of this error is an encoding error which only affects the event log, without compromising the actual protection of the Firewall nor the security of the system. The peculiar thing is that Microsoft misreported in the July patch notes that the fault had already been repaired. However, far from being corrected, The update extended the bug to a greater number of devices. The company has had to rectify and admit that the "error corrected" message was a mistake.In fact, the company has publicly apologized for the misunderstanding and has promised that the next update will include the final solution.
What exactly does the error message on the Firewall mean?
The famous message «Config Read Failed» displayed with event 2042 in the Event Viewer appears when the system expects a certain amount of information from the Firewall, but receives more data than expected on the first read. Although the event is logged as a failure, the service successfully reads the data again on the next attempt and the Firewall continues to function normally. That is, the error is only an internal notification and does not affect the protection of the equipment.
Microsoft has made it clear in its statements that this is a failure linked to an experimental feature that they are testing for the Firewall, but it is not yet active. The result is that The error only affects the registry entry and does not compromise the security of the equipment. Therefore, users can rest assured: they can completely ignore this warning until the update comes out that removes it.
Microsoft's reaction and the confusion among users
One of the most controversial parts of the matter has been the Microsoft's communication management. Initially, the company stated in its official releases that the error was fully resolved in the July update. However, users and various technology media outlets found that the message continued to appear after installing the patch. This led to a rectification by the company, who has acknowledged that the incident remains open and that it was a mistake to mark it as "resolved."
Microsoft has now issued a notice apologizing to its users and confirming that The bug will be permanently fixed in future cumulative updates.. Meanwhile, the company insists there is no cause for alarm and that the error is completely harmlessEven so, the situation has generated some frustration and disbelief among those who trusted the initial official version of events.
Should I be worried? What should I do while we wait for a solution?
Most experts and Microsoft's own support team agree that no further action is required or modify the Firewall settings. The error message, although it may seem alarming, does not pose any real security problems: The Firewall continues to block suspicious connections and protect your computer As before. Since this is related to a feature still in development, the presence of this notice has more to do with internal technical issues than a practical failure.
Microsoft simply recommends wait for the next update, which will include the genuine patch that will remove the erroneous event log entry. Until then, Users can continue to use their devices as normal. and focus on other possible incidents, since this bug, although visually annoying for those reviewing the logs, is completely harmless.
The recent controversy surrounding Windows Firewall bug This once again highlights the importance of clear communication between software manufacturers and users. A registry error can lead to confusion if not properly explained, even more so if it conveys the impression of a nonexistent security risk. Fortunately, Microsoft has already acknowledged its error, apologized openly, and plans to address the issue soon with a new patch. Until then, simply ignore the warnings and trust that the Firewall continues to do its job.
