Microsoft regularly releases updates for Windows 11 to introduce new features and fix bugs reported by users or discovered internally. However, these updates don’t always go smoothly and sometimes lead to new issues.
Recently, Microsoft confirmed that the Windows 11 update KB5043145 is causing a particularly frustrating problem for some users: the infamous blue screen of death (BSOD) followed by an infinite reboot loop.
While system crashes aren’t entirely new, the recurrence of such issues highlights the complexities involved in maintaining system stability while rolling out frequent updates.
Windows 11 update KB5043145 could cause a blue screen or infinite reboot on your PC
Although Windows 11 updates are intended to introduce new features and resolve existing issues, they sometimes inadvertently cause new problems. Such is the case with the optional update KB5043145.
On September 26, 2024, Microsoft released the KB5043145 update for Windows 11, aiming to fix various issues, including bugs in Microsoft Edge and the task manager, which users had previously confirmed. However, shortly after its release, users began reporting new issues linked to the update.
Microsoft has since updated the support documentation for KB5043145, acknowledging that users running Windows 11 versions 22H2 and 23H3 may encounter problems like an endless reboot loop or even a blue screen of death (BSOD).
In an official blog post, Microsoft explained that some users reported that their computers repeatedly restarted or became unresponsive, displaying blue screens after installing the update. In certain cases, the system’s automatic repair tool was triggered after reboot attempts, and sometimes the BitLocker recovery feature was activated.
As highlighted by Bleeping Computer, the Windows automatic repair tool kicks in when the operating system encounters errors that prevent it from booting correctly. Its goal is to diagnose and fix issues with the Windows installation.
Microsoft has urged users who have installed KB5043145 to submit detailed feedback through the Windows 11 Feedback Hub, allowing the company to gather more information and expedite the troubleshooting process. The company assured users it is actively investigating the issue and working on a solution. In the meantime, users are advised to avoid installing the KB5043145 update until a fix is released.
This response is consistent with Microsoft’s past efforts to resolve issues caused by cumulative updates, offering hope that a solution will be available soon.
