[Fix] Windows 11 Update Causing Blue Screen, Boot-Loop Errors

This is yet another instance where Windows users are experiencing issues with their system due to a recent Windows update. On September 26, 2024, Microsoft released KB5043145 – for OS Builds 22621.4249 and 22631.4249.

Although the update was rolled out to bring in new features, including:

• Ability to share local files directly from the search results
• Added Sign out command to the Start menu
• Fixed the non-responsiveness with Microsoft Edge browser and Task Manager
• No need to enter credentials more than once while signing into Outlook or other encrypted email apps.
• Improvements to fix the issues in Windows 11, version 22H2.

Despite this, the Windows update seems to have its own set of issues. Read on to learn more about issues associated with this buggy update and how to resolve them.

Windows Update KB5043145 Causing BSoD and Boot-Loop Errors

Microsoft confirms that the update contains bugs. It added that the USB and Bluetooth devices, including headphones, keyboards, printers, etc., stopped working after the update installation.

Many users are also experiencing their system rebooting multiple times and becoming unresponsive with either a blue or green screen of death. In some cases, the devices are also getting stuck in a boot-loop.

That’s not all. Some users reported that the Automatic Repair tool opened automatically after repeated restart attempts. Moreover, in some cases, this problematic update also triggers BitLocker recovery.

A Reddit user also stated that after a couple of power resets, the update got reverted automatically by booting Windows correctly. However, on reboot, the Windows update started showing the error code 0x800f0845 on the screen.

Some users reported encountering issues with Wi-Fi and Linux features like WSL2. The update stopped WSL2 from working after installation.

Fixes for Windows Update KB5043145

Microsoft has tweeted that the problem can be mitigated using the Known Issue Rollback (KIR), which can reverse the update. However, there is no fix for enterprise users (systems managed by the IT department). It added that the IT admins will need to install the Windows 11 22H2 KB5043145 240904_041021 Group Policy to deploy the KIR until a permanent fix is released.

Until then, here are some other fixes you may try to resolve the blue or green screen of death on Windows 11 systems.

#1 Run System File Checker (SFC) scan

Missing or damaged system files can also cause BSoD errors. To fix the BSoD error, you can run an SFC scan and check for corrupted or damaged system files and replace them with the correct versions.

#2 Uninstall Buggy Windows Update

You can also try uninstalling the buggy Windows Update to solve the issue. To do so, follow Settings > Update & Security > Windows Update > View Update history > Uninstall Update > Uninstall.

#3 Perform System Restore

Sometimes, you may not be able to find the root cause of the BSoD error on your system. In that case, you can try performing a System Restore and rolling your system back to an older or default restore point. This will restore your system to a functional state, free from errors.

What if I can’t access my device data due to this BSoD Error?

Blue screen errors can stop you from booting into your system, putting data at risk. In such a case, you need a professional data recovery software, such as Stellar Data Recovery Professional. The software offers a ‘Create Recovery Drive’ option that lets you create a bootable media, which you can use to boot into the non-responsive or unbootable system and recover your data.

Conclusion:

The dreaded blue screen and boot-loop errors are recurring with the Windows Update KB5043145 for many home and pro edition users of OS builds 22621.4249 and 22631.4249. This certainly raises concerns about your device and data safety, and Microsoft is working on releasing a holistic fix for the issue.

To restore data from such BSoD-affected or non-bootable systems, you can always rely on professional data recovery software.
