Windows 11 September 2024 Update KB5043145: BSOD and Reboot Issues Explained

  • Thread Author
Late last week, Microsoft rolled out the September 2024 preview update numbered KB5043145 for Windows 11, but it seems this wasn't just another routine patch. Instead, numerous users are reporting headaches, with blue screens of death (BSOD) and relentless reboot loops making their Windows experience anything but smooth. Here’s what you need to know about this troublesome update and how to navigate it effectively.

What Happened?​

On September 30, 2024, Microsoft acknowledged that the KB5043145 update, initially intended to resolve several issues—including freezes in Edge and Task Manager—has unfortunately backfired. Users running Windows 11 versions 22H2 and 23H2 are finding themselves in trouble with PCs that restart on their own multiple times or, worse yet, remain unresponsive, displaying the infamous blue or green screens.

Details of the Disruption​

According to Microsoft’s known issues document, the symptoms may include:
  • Continuous restarts leading to the invocation of the Automatic Repair Tool.
  • Unforeseen activation of BitLocker Recovery for some users.
In response to this, Microsoft has urged affected customers to report their issues via the Feedback Hub, feeding into a growing pool of user-ticketed feedback about the problem. As of now, there’s no timeline established for when a fix will be available, but Microsoft reassured users they are actively investigating.

Understanding the Automatic Repair Tool​

If you find your PC has suddenly loaded the Automatic Repair Tool, don’t panic. This component is part of the Windows Recovery Environment (WinRE) and kicks in whenever the operating system senses a critical error that could prevent it from starting up correctly. Think of it as your PC’s built-in mechanic, trying to diagnose and fix issues to ensure it runs smoothly again.

Historical Context: A Pattern of Problems​

This isn’t the first time Windows updates have made waves for all the wrong reasons. The month of August brought issues tied to dual-boot systems running Linux, further complicating an already concerning patch history. Past security updates in July also prompted similar reboot loops and BitLocker lockouts, establishing a worrying trend regarding update reliability—a phrase that’s; unfortunately, become synonymous with Windows patches.

Optional Update: A Silver Lining?​

It’s worth noting that the September KB5043145 update is optional. This gives users the breathing space to hold off on installation until more concrete fixes roll out from Microsoft. If you haven't yet installed it, you're advised to maintain that status quo until the dust settles.

Key Takeaway​

So, fellow Windows users, if you're currently experiencing a delightful cycle of reboot loops or vibrant blue screens, remember you’re not alone in this digital dystopia. It’s always recommended to keep an eye on official communications from Microsoft for updates on this matter. An ounce of prevention is worth a pound of cure—especially in the landscape of operating system updates. Until a clearer solution is presented, proceed with caution, and enjoy those moments when your computer doesn't decide to act up!
