Does Microsoft’s Latest Windows Update Actually Fix Critical Firewall Problems or Make Them Worse?
Microsoft made a big mistake. The company said they fixed a scary firewall error in Windows 11. But they didn’t. In fact, they made it worse.
Here’s what happened. Your Windows 11 computer might show you an error message that looks really bad. It talks about “Windows Firewall With Advanced Security 2042 None.” The error says “Config Read Failed” and “More data is available”.
This error started showing up in June 2025. Microsoft released an update called KB5060829. After people installed it, they began seeing this firewall error pop up every time they restarted their computer.
The Big Mix-Up That Confused Everyone
Microsoft promised they would fix this problem. They said the July 2025 update (KB5062553) would make the error go away. The company even wrote in their official notes that the problem was “fully fixed”.
But that wasn’t true. The error kept happening. In fact, it got worse. More people started seeing the error after the July update than before it.
Here’s what Microsoft originally claimed:
“This update addresses an issue found in Event Viewer as Event 2042 for Windows Firewall with Advanced Security. The event appears as ‘Config Read Failed’ with the message ‘More data is available.'”
This was wrong. The error didn’t get fixed. It spread to more computers.
Microsoft Says Sorry (Finally)
After people complained, Microsoft admitted they made a mistake. The company quietly changed their support documents. They removed the claim that the problem was fixed.
Microsoft’s new statement says: “This disclosure was mistakenly updated to Resolved status on July 8. A resolution for this issue is planned to be included in an update to be released in the coming weeks. We apologize for any inconvenience or confusion”.
Why This Error Shows Up (And Why You Don’t Need to Worry)
The scary-looking error message is actually harmless. Your firewall is working fine. The error only affects what gets written in your computer’s event log.
Here’s what happens behind the scenes:
- Windows tries to read some firewall data
- It gets more information than it expected
- The system logs an error message
- But the firewall keeps working normally anyway
Microsoft says this happens because they’re testing a new firewall feature. The feature isn’t ready yet. But some code got mixed up with it. That’s why you see these fake error messages.
What You Should Do Right Now
Don’t panic. This error won’t hurt your computer. Your firewall is still protecting you. The error message is just noise.
You have a few choices:
- Ignore the error completely – This is what Microsoft recommends
- Wait for the real fix – Microsoft says they’ll release a proper update soon
- Remove the June update – You can uninstall KB5060829 if the error messages bother you
How to Remove the Update That Started This Mess
If seeing the error messages drives you crazy, you can remove the June update:
- Open Settings
- Go to Windows Update
- Click Update History
- Select Uninstall updates
- Find KB5060829 and click Uninstall
- Restart your computer
Microsoft messed up twice. First, they released an update that created fake error messages. Second, they falsely claimed they fixed the problem when they actually made it worse.
But here’s the good news. Your computer is safe. The firewall error looks scary but does nothing bad to your system. Microsoft promises a real fix is coming soon.
This whole situation shows why you should be careful about installing Windows updates right away. Sometimes it’s better to wait and see what problems other people find first.
The error will keep showing up every time you restart your computer until Microsoft releases the real fix. But remember – it’s just a fake error message. Your firewall is working fine, and your computer is still protected.
