On Hyper-V hosts, warn before running destructive actions on host
When a Windows Server 2016 machine is a Hyper-V host, attempting to run system-wide destructive actions, such as sysprep, should be warned against more vocally than typical actions, such as shutdown. Such actions have far greater ramifications than mundane actions such as restart or shutdown. This will provide visual queues to administrators who are working directly on Hyper-V hosts and using the "Connect..." feature of Hyper-V Manager to open consoles to VMs on the host. Such destructive actions are frequently needed when building new VMs, but are very rarely needed on host machines.
