Microsoft publicly acknowledged a known issue causing Windows Server 2022 virtual machine blue screens and boot failures on VMware ESXi hosts.
"Affected VMs will receive an error with a blue screen and Stop code : PNP DETECTED FATAL ERROR," Microsoft said in an update to the Windows release health dashboard.
Windows administrators with impacted devices have also noted that uninstalling the problematic KB5031364 update will also resolve the issue, allowing VMs to start up again without any problems.
Microsoft also issued emergency Windows Server updates in January and December 2022 to fix known issues causing Hyper-V VMs to no longer start and problems while creating new VMs on some Hyper-V hosts.
October Windows Server updates cause Hyper-V VM boot issues.
Windows 11 21H2 and Windows Server 2012 reach end of support.
