Yes, I am getting a output source ZIP that is identical to the official source ZIP (except for the minor changes I made to hardcode the git commit # and the version number)
I'm using a clean Windows 2012 system with just the Windows SDK v7.0.7600.16385.40715 installed.
I'm opening the CMD prompt shortcut that the SDK setup and then CDing to the dir where the source is extracted and running "build-package.bat"
Yet the binaries that are output are not identical to the official builds which leads me to believe that one of the tools I'm using is a different version from those that you are using on the official build server.
Do you happen to have a list of what tool versions you have installed on the official build server?
