Windows node in k8s cluster

hello everyone,
when were trying to adding windows node to the cluster, we try to install kubeadm.exe, kubelet.exe and other URLs in PrepareNode.ps to add it to our environment but the URLs does not exist
such as https://dl.k8s.io/$KubernetesVersion/bin/windows/amd64/kubelet.exe

source code in this URL
https://github.com/kubernetes-sigs/sig-windows-tools/blob/master/kubeadm/scripts/PrepareNode.ps1

What is the value of $KubernetesVersion?

Kubernetes version : 1.17.2

Try v1.17.2 instead. I figured this out from the example usage that the script provides:

PS> .\PrepareNode.ps1 -KubernetesVersion v1.19.3 -ContainerRuntime containerD

Also the documentation here hints to the formatting as well.
