MSI is warning people not to install the new Windows 11 KB5029351 update because it can result in a BSOD on certain hardware, including the company’s own 600/700 series motherboards. “Microsoft has received reports of an issue in which users are receiving an ‘UNSUPPORTED_PROCESSOR’ error message on a blue screen after installing updates released on August 22, 2023 (KB5029351) and then restarting their device,” Microsoft confirmed on its support site. Those who have installed the update and are encountering BSODs have been advised to uninstall it, although restoring to an older BIOS may be required.
MSI has received several reports of users encountering a Blue Screen of Death that has an error message that reads “UNSUPPORTED_PROCESSOR” with MSI’s 600/700 series motherboards after installing the Windows 11 update, KB5029351 Preview.
Both MSI and Microsoft are aware of the “UNSUPPORTED_PROCESSOR” error and have begun investigating the root cause. While the investigation is underway, we recommend that all users temporarily refrain from installing the KB5029351 Preview update in Windows. We will keep you updated on the progress of our investigation.
If you have already encountered this issue, KB5029351 might automatically be uninstalled to allow Windows to restore to normal. However, if KB5029351 is not automatically uninstalled, we recommend reverting your BIOS to the previous version and uninstalling KB5029351 from Windows.
