For hyper-v you can use PowerShell to manage VM's, see the details here: https://docs.microsoft.com/en-us/virtualization/hyper-v-on-w...

I use Hyper-v for years and I rarely create new VMs, this is why I use GUI, it is convenient if you don't do this often enough to remember the syntax and params. Most people that I know are in the same boat, but for mass deployments or automated deployments PowerShell is the way to go.
