Fresh machine where and for whom? I doubt a simple batch script will get you very far (setup.exe exists for a reason...), and I doubly-doubt you would have enough overlap in the process that something that can convert the steps to bash would be an advantage. The only advantage I see for batsh is that it looks nicer to write in for the tiny subset of batch it supports. But then so is pretty much anything else -- it wouldn't surprise me if someone has already written a DSL in a well known language that can output to batch or powershell, we don't need a whole new language for this.
