+# Customize node configuration for Azure Kubernetes Service (AKS) node pools
 
 Customizing your node configuration allows you to configure or tune your operating system (OS) settings or the kubelet parameters to match the needs of the workloads. When you create an AKS cluster or add a node pool to your cluster, you can customize a subset of commonly used OS and kubelet settings. To configure settings beyond this subset, [use a daemon set to customize your needed configurations without losing AKS support for your nodes](support-policies.md#shared-responsibility).
 
-## Register the `CustomNodeConfigPreview` preview feature
-
-To create an AKS cluster or node pool that can customize the kubelet parameters or OS settings, you must enable the `CustomNodeConfigPreview` feature flag on your subscription.
-
-Register the `CustomNodeConfigPreview` feature flag by using the [az feature register][az-feature-register] command, as shown in the following example:
-
-```azurecli-interactive
-az feature register --namespace "Microsoft.ContainerService" --name "CustomNodeConfigPreview"
-```
-
-It takes a few minutes for the status to show *Registered*. Verify the registration status by using the [az feature list][az-feature-list] command:
-
-```azurecli-interactive
-az feature list -o table --query "[?contains(name, 'Microsoft.ContainerService/CustomNodeConfigPreview')].{Name:name,State:properties.state}"
-```
-
-When ready, refresh the registration of the *Microsoft.ContainerService* resource provider by using the [az provider register][az-provider-register] command:
-
-```azurecli-interactive
-az provider register --namespace Microsoft.ContainerService
-```
-
-[!INCLUDE [preview features callout](./includes/preview/preview-callout.md)]
-
-## Install aks-preview CLI extension
-
-To create an AKS cluster or a node pool that can customize the kubelet parameters or OS settings, you need the latest *aks-preview* Azure CLI extension. Install the *aks-preview* Azure CLI extension by using the [az extension add][az-extension-add] command. Or install any available updates by using the [az extension update][az-extension-update] command.
-
-```azurecli-interactive
-# Install the aks-preview extension
-az extension add --name aks-preview
-
-# Update the extension to make sure you have the latest version installed
-az extension update --name aks-preview
-```
