If you have not yet installed Minikube, refer to this blog first: https://coding-stream-of-consciousness.com/2018/11/08/installing-minikube-on-windows-10/.
Assuming you have Minikube running, open another command prompt (I used an administrator one). Then run:
Once that is up, you can go to this link: http://localhost:8001/api/v1/namespaces/kube-system/services/kubernetes-dashboard/proxy/#!/node?namespace=default and the kubernetes UI should be available.
The Kubernetes documentation may recommend a different link that does not work. I believe this is probably because Minikube is out of date compared to the current Kubernetes releases; but maybe it is just a documentation error.
For the record in case it changes in the future, the link from the Kubernetes documentation is: http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/.
