cp -R /mnt/c/Users/YOUR-WINDOWS-USER/.minikube/client.crt /home/YOUR-LINUX-USER/.kube/minikube-certs/
cp -R /mnt/c/Users/YOUR-WINDOWS-USER/.minikube/client.key /home/YOUR-LINUX-USER/.kube/minikube-certs/
cp -R /mnt/c/Users/YOUR-WINDOWS-USER/.kube/config /home/YOUR-LINUX-USER/.kube/minikube
sed -i -e 's/C\:\\Users\\YOUR-WINDOWS-USER\\.minikube\\/\/home\/YOUR-LINUX-USER\/.kube\/minikube-certs\//g' /home/YOUR-LINUX-USER/.kube/minikube
```

Replace `YOUR-WINDOWS-USER` and `YOUR-LINUX-USER`.
