Hi@akhtar,
To install Minishift manually on Windows using Windows Installer, download the software https://github.com/minishift/minishift/releases/download/v1.18.0/minishift-1.18.0-windows-amd64.zip link and execute the installer in your windows system.
After that, you can start your Minikshift using the below-given command.
$ minishift.exe start --vm-driver=virtualbox --network-nameserver 8.8.8.8
It will take 5-10 minutes to configure the Minishift cluster.
