Build windows with vsphere-iso but do not provision?

I’m trying to set up a packer build of windows using the vsphere-iso builder, but don’t want to provision. I want Windows to be installed, and I do all my config via the autounattend.xml file, and once thats complete, to just shut the VM down and convert it to a template. I’ve tried a shell-local provisioner that just does [“echo foo”] but that doesn’t seem to work.

We’re trying to create a Windows template without openSSH or WinRM available, so a bit weird.
