+Note the following limitations when working with Windows nodes managed by the WMCO (Windows nodes):
+
+* The following {product-title} features are not supported on Windows nodes:
+** Red Hat OpenShift Developer CLI (odo)
+** Image builds
+** OpenShift Pipelines
+** OpenShift Service Mesh
+** OpenShift monitoring of user-defined projects
+
+* The following Red Hat features are not supported on Windows nodes:

+** link:https://developers.redhat.com/products/openshift-local/overview[Red Hat OpenShift Local]
+
+* Windows nodes do not support pulling container images from private registries. You can use images from public registries or pre-pull the images.
+
+* Windows nodes do not support workloads created by using deployment configs. You can use a deployment or other method to deploy workloads.
+
+* Windows nodes are not supported in clusters that use a cluster-wide proxy. This is because the WMCO is not able to route traffic through the proxy connection for the workloads.
+
+* Windows nodes are not supported in clusters that are in a disconnected environment.
+
+* {productwinc} supports only in-tree storage drivers for all cloud providers. 
+
+* Kubernetes has identified the following link:https://kubernetes.io/docs/concepts/windows/intro/#limitations[node feature limitations] :
+** Huge pages are not supported for Windows containers.
+** Privileged containers are not supported for Windows containers.
+** Pod termination grace periods require the containerd container runtime to be installed on the Windows node.
+
+* Kubernetes has identified link:https://kubernetes.io/docs/concepts/windows/intro/#api[several API compatability issues].
