Late last week, Microsoft released the September 2024 KB5043145 preview update, but already the Redmond tech giant is warning that some Windows 11 PCs may suffer from reboot loops or freeze to a blue screen

The optional update was released along with a number of fixes for other issues, including Edge and Task Manager freezes

Microsoft almost immediately released support documentation for known issues to the KB5043145 update, which, as Bleeping Computer discovered, may cause problems for Windows 11 22H2 and 23H2 users

“After installing this update, some customers have reported that their devices reboot repeatedly or become unresponsive with blue or green screens,” Microsoft wrote in the document The report states, “In some devices, after repeated reboots, the AutoRepair tool is automatically triggered In some cases, BitLocker recovery may also launch”

In a separate document, Microsoft urged Windows 11 users affected by this issue to report the problem to the feedback hub and provide details

As of this writing, Microsoft has acknowledged the issue, but has no update on when it will be fixed or what is causing the errors people are seeing

“We are currently investigating this issue We will provide an update as more information becomes available,” the company wrote

If you see the Auto Repair tool enabled, it is part of the Windows Recovery Environment, which automatically opens on PCs that are experiencing problems that lead to errors or crashes, diagnoses the operating system, and may repair it so it can boot properly

As reported by Bleeping Computer, the last few updates have introduced new problems with PCs: the August 2024 Windows security update introduced a problem with Linux booting on dual-boot systems with Secure Boot enabled introduced

August also introduced a bug in the July 2024 security update that fixed a boot issue on Windows Server 2019 systems and caused some PCs to boot into BitLocker recovery

July saw the repair of issues caused by the June KB5039302, which also caused a reboot loop and taskbar issues

If you have not installed this update, you can avoid it for now until a new fix is released by Microsoft, as this update is optional
