CTOnews.com November 9 news, Microsoft today updated the Windows health console page, acknowledging that Windows Server 2022, which the VMware ESXi virtual machine is running, will cause the device blue screen and "PNP DETECTED FATAL ERROR" code after installing the cumulative update KB5031364 in October this year.

Microsoft has confirmed that this issue will not affect all systems, and CTOnews.com attached an official introduction as follows:

Installing KB5031364 updates on a VMware ESXi virtual host may cause Windows Server 2022 to fail to boot.

The affected virtual machine pops up with a blue screen error: PNP DETECTED FATAL ERROR. This issue affects only client virtual machines on VMware ESXi hosts with the following configuration:

AMD Epyc physical processor

Expose IOMMU to Guest operating system is enabled for the virtual machine in the VMware setting.

Enable Virtualization-based Security in Windows Server 2022.

System Guard secure Startup is enabled in Windows Server 2022.

Microsoft offers a temporary solution:

Solution: to alleviate this problem, you can disable "expose IOMMU to guest operating systems". Important: this workaround should only be used in environments where you do not need to enable expose IOMMU to Guest OS.

CTOnews.com Note: when this option is turned on, the user's operating system can improve I / O bus performance through the DMA (or direct memory access) of the system RAM.

Microsoft said it would release a fix in the middle of this month and is expected to release the patch on Tuesday, November 2023.
