Windows Admin Center can enable the load-balancing recommendation feature, but it does not actively redistribute VMs by itself. It only exposes the cluster’s built-in Load Balancer for VM placement recommendations.

If VMs are not moving, check:

  • Whether the cluster has Dynamic Optimization enabled (Failover Cluster Manager or PowerShell). WAC only toggles the flag but does not trigger movement.
    • Whether the cluster nodes show balanced CPU and memory usage. If the cluster does not detect imbalance, no movement happens.
    • Whether the cluster is in maintenance mode or has constraints such as anti-affinity rules.
    • Whether live migration is allowed between all nodes.

Start troubleshooting from Failover Cluster Manager or by running cluster validation. WAC is only a management surface; the actual balancing logic depends on the cluster configuration.
