`kubectl` not found. If you need it, try: 'minikube kubectl -- get pods -A'

I installed minikube in Windows 10 . I am able to start minikube

**C:\WINDOWS\system32>minikube start
* minikube v1.15.1 on Microsoft Windows 10 Pro 10.0.18363 Build 18363
* Using the hyperv driver based on existing profile
* Starting control plane node minikube in cluster minikube
* Restarting existing hyperv VM for "minikube" ...
* Preparing Kubernetes v1.19.4 on Docker 19.03.13 ...
* Verifying Kubernetes components...
* Enabled addons: storage-provisioner, default-storageclass
* kubectl not found. If you need it, try: 'minikube kubectl -- get pods -A'
* Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default**

But there is a warning in above output ( 2nd last line ) says kubectl not found. If you need it, try: 'minikube kubectl -- get pods -A'

After that I executed this command too minikube kubectl -- get pods -A

Still getting below error while trying kubectl

C:\WINDOWS\system32>kubectl
