Accepted Answer

1. **VM Resizing (Box 1):** The Scale Set's upgrade policy is set to `Automatic` (as shown in the `UpgradePolicy` block of `Get-AzVmss`). When the model config is updated (e.g. changing the VM size), all VM instances in the scale set are immediately updated to conform to the new model config at the same time, which is **4** instances.
2. **OS Upgrades (Box 2):** For automatic OS image upgrades in a Windows VMSS, `enableAutomaticUpdates` must be set to `false` in the model definition (which disables in-VM patching so Azure can manage it cleanly at the platform level). When a new image is published, the rolling upgrade process applies it to a maximum of 20% of VM instances at a time, with a minimum of **1** instance. 20% of 4 is 0.8, which rounds up to the minimum of **1** instance at a time.
