Consider the following scenario:
You set up a Hyper-V virtual machine on a host computer that is running Windows Server 2012 R2 or Windows 8.1.
You set the Automatic Stop Action setting of the virtual machine to Shut down the guest operating system.
You restart the host computer.
In this scenario, the guest operating system (OS) on the virtual machine does not shut down. Additionally, after you restart the virtual machine, the following event is logged on the guest OS: Note If the computer is part of a cluster, this issue does not occur.
This issue occurs because the Virtual Machine Management Service tries to shut down the virtual machine by using the Virtual Machine Worker process. However, the process encounters a logic failure that causes the shutdown operation to fail and reverts the shutdown operation. Therefore, power cycling occurs instead of a clean shutdown.
