KB5043145 issue

Microsoft’s recent non-security preview update, KB5043145, released for Windows 11 (23H2 and 24H2), is causing significant issues for users.

The company has confirmed that the update is causing some systems to restart multiple times, become unresponsive with blue or green screens, or boot into BitLocker Recovery via the Windows Automatic Repair Tool.

Microsoft has received customer reports of devices restarting multiple times or becoming irresponsive with blue or green screens after trying to install the September 2024 non-security preview Windows update (KB5043145). According to the reports, some devices automatically open the Automatic Repair tool after repeated reboot attempts. This tool diagnoses and resolves common issues that might prevent your device from booting properly. In some cases, BitLocker recovery can also be triggered.

Microsoft says it’s investigating the issue and will provide an update once more information is available. The company is urging affected users to raise an issue on Feedback Hub to help expedite its investigation.
