KB: KB5022842?

"Windows Server 2022 may not start up after installing KB5022842 on guest virtual machines (VMs) using that version of VMware ESXi, " Microsoft said.

Note: ?Other hypervisor platforms, including bare metal, may potentially be affected by this problem, according to some administrator reports.

Work Around Solutions:

• Upgrade to vSphere ESXi 8.0 on the ESXi host that hosts the virtual machine in issue.
• On the VMs, disable "Secure Boot."
