* Previously, if a Windows VM had its PowerShell `ExecutionPolicy` set to `Restricted`, the Windows Instance Config Daemon (WICD) could not run the commands on that VM that are necessary for creating Windows nodes. With this fix, the WICD now bypasses the execution policy on the VM when running PowerShell commands. As a result, the WICD can create Windows nodes on the VM as expected. (link:https://issues.redhat.com/browse/OCPBUGS-30995[*OCPBUGS-30995*])

* Previously, if reverse DNS lookup failed due to an error, such as the reverse DNS lookup services being unavailable, the WMCO would not fall back to using the VM hostname to determine if a certificate signing requests (CSR) should be approved. As a consequence, Bring-Your-Own-Host (BYOH) Windows nodes configured with an IP address would not become available. With this fix, BYOH nodes are properly added if reverse DNS is not available. (link:https://issues.redhat.com/browse/OCPBUGS-36643[*OCPBUGS-36643*])

* Previously, if there were multiple service account token secrets in the WMCO namespace, scaling Windows nodes would fail. With this fix, the WMCO uses only the secret it creates, ignoring any other service account token secrets in the WMCO namespace. As a result, Windows nodes scale properly.

* Previously, Windows nodes were unable to pull from image mirror registries if an organization name or namespace was included in the source of the `ImageTagMirrorSet` (ITMS) object. With this fix, you can include an organization name or namespace in the `ITMS` object. With this change, additional guidelines and requirements around using mirror registries have been added to the {product-title} documentation. For more information, see _Using Windows containers with a mirror registry_. (link:https://issues.redhat.com/browse/OCPBUGS-55915[*OCPBUGS-55915*])

* Previously, the {product-title} documentation lacked information about WMCO support for the installer-provisioned infrastructure (IPI) and the user-provisioned infrastructure (UPI) installation methods. With this fix, the documentation reports that the IPI method is the preferred installation method and can be used with all platforms. The UPI method is limited to specific use cases. For more information, see _WMCO supported installation method_. (link:https://issues.redhat.com/browse/OCPBUGS-44237[*OCPBUGS-44237*])
