This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:
- Addresses issue that causes Hyper-V VMs that are replicated using Hyper-V Replica or Azure Site Recovery to stop responding at 92% if a Windows Server 2016 Failover Cluster is set up with NIC Teaming enabled. The issue also occurs while stopping the VM, during Live Migration, while stopping the VMMS service, or during Host node shutdown. The user must then use a hard restart on the host machine to recover.
