Are Repetitive Windows Firewall Warnings Causing Trouble? Discover the Simple Update With the Positive Effect

Are Repetitive Windows Firewall Warnings Causing Trouble? Discover the Simple Update With the Positive Effect

What Was the Problem?

After the June 2025 preview update was installed on Windows 11 version 24H2, each reboot made the system log a warning in Event Viewer.

The warnings read, “Config Read Failed” with “More data is available.”

These messages did not mean the firewall was broken. The firewall still worked, but the logs made it seem like something was wrong.

The error was caused by a new feature Microsoft was building, but that feature had not been completely added to Windows yet.

What Did Microsoft Do?

Microsoft told IT admins to simply ignore the repeated error logs. The errors did not affect security or cause any real risk.

On July 8, the status was accidentally marked as fixed, but users kept seeing the error. Microsoft quickly recognized the error was still active and changed the status back. They then promised a real fix would be released soon.

On July 22, Microsoft released the KB5062660 preview update. Installing this update stops the repeated firewall warnings from showing up in Event Viewer.

Who Gets the Fix Now?

If you install the optional KB5062660 preview update, you will stop seeing the firewall warnings right away.

Everyone else will get the fix during the August Patch Tuesday updates automatically.

How to Fix the Windows Firewall Warning

  1. Go to Settings in Windows 11.
  2. Click “Windows Update.”
  3. Find and install the “Optional Cumulative Update Preview (KB5062660).”
  4. Restart your device.

After these steps, the firewall warnings should stop appearing.

Why Did the Error Appear?

  • The error logs appeared because Windows tried to use new software code that was not complete.
  • Every reboot made Windows log an event about not reading some firewall settings fully.
  • The actual protection stayed active, but the event logs made people worry.

Impact and User Feedback

Many users found the repeated error messages confusing and distracting, but no real security threat existed.

After installing the fix, most people noticed the messages stopped and said the update worked well.

A few people with older computer parts had trouble installing the update, but there were no widespread problems.
