Beware! Windows 11 KB5043145 Update May Be to Blame for Reboot Loops and Blue Screens
The world of technology is constantly evolving, and while software updates are intended to improve the user experience, they occasionally introduce more problems than they solve. Microsoft’s September 2024 KB5043145 update for Windows 11 is a case in point. This optional update, which was supposed to address several issues, has instead led to unexpected system failures, including reboot loops, blue screens, and device freezes.
What Went Wrong with KB5043145?
Released in late September 2024, the KB5043145 update aimed to resolve problems such as freezes in Microsoft Edge and the Task Manager. Unfortunately, many users soon discovered that their systems were worse off after installing it. Just a day after the update became available, Microsoft added a critical warning to its support documentation, highlighting new issues specifically affecting users of Windows 11 versions 22H2 and 23H2.

According to reports, the most serious problems include:
- Reboot Loops: Affected devices automatically restart multiple times, sometimes without any clear resolution.
- System Freezes: In many cases, the computer becomes entirely unresponsive, often accompanied by blue or green screens.
- Automatic Repair Tool Activation: When a device fails to boot correctly after repeated restart attempts, the built-in Windows Automatic Repair tool kicks in. While this tool is designed to diagnose and fix boot-related issues, it doesn’t always succeed in resolving the problem.
- BitLocker Recovery: In some instances, BitLocker, Windows’ encryption feature, is also triggered, causing users to enter BitLocker recovery mode unexpectedly.
Microsoft’s Response and Next Steps
Microsoft has acknowledged the severity of these issues and is actively working on a fix. “We are currently investigating this issue. We will provide an update when more information is available,” the company stated. Affected users have been encouraged to file a report using the Feedback Hub to assist the development team in pinpointing the problem’s root cause.
This isn’t the first time Microsoft has dealt with update-induced boot issues in 2024. In fact, several other problems have surfaced this year, affecting not only Windows 11 but also other Microsoft operating systems, including Windows Server 2019. In August, Microsoft fixed bugs that caused boot failures and freezes on Windows Server systems, as well as issues affecting dual-boot systems running Linux with Secure Boot enabled. The company has also dealt with BitLocker recovery triggers caused by earlier updates.
What Should Windows 11 Users Do?
If you haven’t installed the KB5043145 update yet, it might be best to wait until Microsoft releases a more stable fix. For users already impacted by these issues, here are some steps to consider:
- Use the Feedback Hub: If your system is affected, share your experience with Microsoft via the Feedback Hub, helping them to address the issue more quickly.
- Boot into Safe Mode: If your device is stuck in a reboot loop or showing a blue screen, try booting into Safe Mode, which might allow you to uninstall the KB5043145 update.
- Check for Updates: Keep an eye on the Windows Update settings. Microsoft will likely release an update soon to resolve the issues caused by KB5043145.
A Growing Pattern of Update Issues?
While no software company can guarantee flawless updates, 2024 has seen a noticeable uptick in issues following Windows updates. Whether it’s BitLocker recovery problems, dual-boot challenges, or reboot loops, many users are becoming wary of optional updates like KB5043145.
It might be time for Microsoft to revisit its update testing procedures, ensuring a more reliable user experience with fewer post-update headaches.
The KB5043145 update was intended to be a helpful improvement for Windows 11, but instead, it’s causing major disruptions for some users. If you’ve already installed this update and are experiencing issues, know that you’re not alone. Microsoft is actively working on a fix, and in the meantime, it’s wise to avoid installing this update unless absolutely necessary.
