 The following information details the supported platform versions, Windows Server versions, and networking configurations for the Windows Machine Config Operator (WMCO). See the vSphere documentation for any information that is relevant to only that platform.

 == WMCO supported installation method
 
 The WMCO fully supports installing Windows nodes into installer-provisioned infrastructure (IPI) clusters. This is the preferred {product-title} installation method.
 
 For user-provisioned infrastructure (UPI) clusters, the WMCO supports installing Windows nodes only into a UPI cluster installed with the `platform: none` field set in the `install-config.yaml` file (bare-metal or provider-agnostic) and only for the xref:../../windows_containers/byoh-windows-instance.adoc#byoh-windows-instance[BYOH (Bring Your Own Host)] use case. UPI is not supported for any other platform.

+==== WMCO kubelet configuration changes 
+// https://github.com/openshift/windows-machine-config-operator/pull/2709
+
+With this release, the WMCO now sets the following values in the `KubeletConfig` custom resource (CR):
+
+* The `system-reserved` parameter is now set to 2GiB of memory for system processes, as recommended in the link:https://kubernetes.io/docs/concepts/configuration/windows-resource-management/#resource-reservation[Kubernetes documentation].
+* The `enforceNodeAllocatable` with  a default value of `none`. Previously, the value was set to `[]` to avoid a known issue. Both settings disable the enforcement of node allocatable resource limits.
+* The `evictionHard` parameters, `imagefs.available` and `nodefs.available` are now set to `15%` and `10%` respectively, as recommended in the link:https://kubernetes.io/docs/concepts/scheduling-eviction/node-pressure-eviction/#eviction-signals[Kubernetes documentation] 
+
+The `KubeletConfig` object configures the kubelet service, which runs on each node in the cluster to ensure that containers in a pod are running.
