 When you create your AKS cluster, you specify the `--windows-admin-password` and `--windows-admin-username` parameters to set the administrator credentials for any Windows Server nodes on the cluster. If you didn't specify administrator credentials when you created a cluster by using the Azure portal or when setting `--vm-set-type VirtualMachineScaleSets` and `--network-plugin azure` by using the Azure CLI, the username defaults to *azureuser* and a randomized password.
 
 To change the administrator password, use the `az aks update` command:

 ## How many node pools can I create?
 
 The AKS cluster can have a maximum of 100 node pools. You can have a maximum of 1,000 nodes across those node pools. For more information, see [Node pool limitations][nodepool-limitations].
