Update, October 2, 2024: This story, originally published on October 1, now contains details about a temporary fix for Windows 11 reboot loop issues.

An update for Windows 11 users that fixes a number of issues, including system crashes when using the Edge web browser, has been found to bring with it some issues of its own. Microsoft has warned all users that the September 2024 update KB5043145 (OS builds 22621.4249 and 22631.4249) may cause devices to keep rebooting. Yes, the dreaded blue screen of death has returned once again for Windows users still reeling from July's CrowdStrike update fiasco. However, this time some users also observed the green screen freezing. Here's what you need to know:

The Microsoft warning for all Windows 11 users

Microsoft's latest update to the Windows 11 operating system was released just a few days ago, on September 26th, but that was so long ago that many people are upset about the consequences of installing it. While KB5043145 was supposed to offer new features such as the ability to share local files directly from search results displayed on the taskbar and add a logout command to the Start menu, as well as fix an Edge browser and Task Manager freezing issue, this is not everything it introduced.

Microsoft has now confirmed that the update may result in customers having a Windows 11 system that “reboots multiple times or becomes unresponsive with blue or green screens” after installation. But that's not all, some users have also reported that the automatic repair tool opens after several restarts. On the security front, Microsoft has also confirmed that BitLocker Recovery can be triggered by this system update error, which is annoying to say the least.

Unfortunately, there doesn't seem to be any workaround, at least for now. Microsoft simply said, “We are currently investigating this issue.” We will provide an update when more information becomes available.”

If you haven't uninstalled the Windows 11 update yet, I would recommend waiting until Microsoft discovers and fixes the error.

Microsoft confirms new, albeit temporary, reboot fix for Windows 11 users

According to Bleeping Computer, Microsoft has provided a temporary solution to Windows 11's blue screen and green screen restart loop issues. But let's be honest, it's not so much a solution as it is the “best as if we've ever installed” solution from Microsoft. So what should you do if your system keeps rebooting, the BitLocker automatic repair feature appears, or your USB and Bluetooth devices stop connecting? Roll back the update using the Known Issues Rollback feature. This may remove non-security updates and should get you back up to speed. Bleeping Computer reports that enterprise users need to install the Windows 11 22H2 KB5043145 240904_041021 Rollback Group Policy for known issues. “We are working to include the solution in a future Windows update,” Microsoft said. “Once the fix is ​​released, organizations will no longer need to install and configure this Group Policy to resolve this issue.”
