- kubeadm: Allowed to download certificate secrets uploaded by `init` or `upload-certs` phase, allowing to transfer certificate secrets (certificates and keys) from the cluster to other master machines when creating HA deployments. ([#74168](https://github.com/kubernetes/kubernetes/pull/74168), [@ereslibre](https://github.com/ereslibre))

- Updated base image for Windows pause container images to one built on Windows machines to address limitations of building Windows container images on Linux machines. ([#110379](https://github.com/kubernetes/kubernetes/pull/110379), [@marosset](https://github.com/marosset))

- DisableAvailabilitySetNodes is added to avoid VM list for VMSS clusters. It should only be used when vmType is "vmss" and all the nodes (including control plane nodes) are VMSS virtual machines.

[#57159](https://github.com/kubernetes/kubernetes/issues/57159).

*   If you are adding Windows Server Virtual Machines as nodes to your Kubernetes environment, there is a compatibility issue with certain virtualization products. Specifically the Windows version of the kubelet.exe calls `GetPhysicallyInstalledSystemMemory` to get the physical memory installed on Windows machines and reports it as part of node metrics to heapster. This API call fails for VMware and VirtualBox virtualization environments....
