Windows 11 KB5062553 Update (July 2025): Fixes, Issues & Workarounds

Here’s a clear summary of the issues and solutions for Windows 11 KB5062553 (July 2025 Update) based on your Windows Latest source and additional community forum highlights:

Key Issues with KB5062553​

• Update Fails with Errors: Common failure codes include 0x8007371b, 0x800f0991, 0x80073712, and 0x80071a2d. These errors may cause the update to stop, roll back changes, or get stuck at a high percentage (e.g., 95% installing).
• Windows Firewall Errors: Even after installation, Event Viewer may show new or more “Event 2042” Firewall errors, labeled “Config Read Failed.” This appears to be a false error related to a future feature, according to Microsoft.
• Performance Issues: Rare reports of install GUI freezing except for the mouse cursor—sometimes requiring a forced shutdown.

Official Status and Acknowledgement​

• This is a mandatory (“critical security”) update for Windows 11 24H2.
• The Firewall error that appeared in the previous optional June update (KB5060829) was supposed to be fixed in July, but is now affecting even more users after KB5062553.
• Microsoft is aware but hasn’t offered an immediate fix for the event log Firewall error.

Solutions and Workarounds​

• Use Offline .msu Installer
• Go to the Microsoft Update Catalog.
• For Intel/AMD PCs, first manually download and install SSU KB5043080, then install KB5062553.
• For ARM PCs, ensure you use the ARM-specific SSU and update package.
• If .msu Also Fails:
• Use the Media Creation Tool (from Microsoft’s official site) to perform an in-place/repair upgrade. This preserves your files and apps, successfully applying the update in almost all cases.
• False Firewall Errors:
• These are logged in Event Viewer; no known impact on actual connectivity or firewall protection.
• No user-side fix yet; Microsoft says it’s due to a future update mechanism, and more info should be coming.
• If System Freezes During Install:
• Perform a hard shutdown (hold power button).
• On reboot, Windows may show a BSOD (“internal power error”) but generally recovers after restart.

Additional Community Notes​

• This update also brings several new features and security enhancements (taskbar, search, accessibility, UI tweaks).
• For detailed logs or troubleshooting, regularly check the Windows Release Health Dashboard for known issues and fixes as they’re updated.

KB5062553 update keeps failing at 99% installation. Should we not have KB5063666 as a separate update first? I can't find KN5063666 in the Catalog for manual downloading and installation.

 

[ChatGPT]

You're encountering a common issue where the KB5062553 update fails at 99% installation, and you're also unsure about the status of KB5063666, which isn't showing up in the Microsoft Update Catalog.
Here’s how to tackle this:

1. KB5062553 Fails at 99%​

This often points to system conflicts, corrupted update files, or dependency issues. Try the following:

• Run the Windows Update Troubleshooter:
  Go to Settings > System > Troubleshoot > Other troubleshooters > Windows Update > Run.
• Clear the Windows Update Cache:
  1. Open Command Prompt as Administrator.
  2. Run:
     

     net stop wuauserv
     net stop bits
     del /f /s /q %windir%\SoftwareDistribution\*.*
     net start wuauserv
     net start bits

  3. Try the update again.
• Check for Pending Restarts:
  Sometimes a pending restart blocks updates. Restart your PC and then retry.

2. About KB5063666​

• Should KB5063666 be installed first?
  Usually, Windows handles update dependencies automatically. There’s no general requirement to manually install one before the other unless specifically stated in Microsoft’s documentation or the update release notes.
• Missing from the Update Catalog:
  Are you sure about the "KN5063666" KB number? Double-check that it's not a typo.
  Also, some updates (especially those with “KN” or “N” prefixes) are region/language/edition-specific and might not appear for all Windows editions or in the Update Catalog.

3. Manual Workarounds​

• Search the Catalog Carefully:
  Use the exact KB number (try both KB5063666, KN5063666, and just 5063666) here: Microsoft Update Catalog
  If it doesn't exist, it may not be a public standalone update.
• Install via PowerShell:
  If you find a CAB or MSU file, you can install it manually:
  DISM /Online /Add-Package /PackagePath:"[path to .cab]"
• Check for Known Issues:
  Microsoft often posts known issues and workarounds on their release notes and forums.

4. If All Else Fails​

• Check Windows Event Viewer:
  Look for error codes or messages under Windows Logs > Setup.
• Update Using Media Creation Tool/In-Place Upgrade:
  Download from the official Microsoft site and try an in-place upgrade, which can often resolve stuck updates without data loss.
