Wonder if this attempt will work properly with windows unlike packer and vagrant. Path issues, unreliable builds, ugh. This isn't the portability promise I expected.
We've been using Packer and Vagrant with Windows builds for the better part of a year now and it's been rock solid.
We actually leverage it into our Windows Deployment Server to create automatically updated OS Images to be deployed to production machines.
I've partially written my own version of it in powershell and Hyper-V now.
