In the beginning of the tutorial there's this big red warning message:
An upgraded Windows cannot be sysprepped. As this method is based in sysprepping, this tutorial is valid only for Windows setups which have not been upgraded.
This means that if you have for instance in-place upgraded Vista or Seven to Eight you cannot sysprep and this tutorial cannot be used in your case. The same applies if you have upgraded Windows 8 to Windows 8 Pro or Windows 8 to 8.1. An upgraded Windows cannot be sysprepped.
Notice that a repair install is also an upgrade install, so if you have ever done a repair install (= in-place upgrade to same edition), you cannot sysprep.
When sysprepping an existing Windows setup, it only works if the Windows 8 was installed clean and has never been upgraded or repaired using repair install, or if it is the original pre-installed Windows 8
Although I have repeatedly told that relocating ProgramData will cause Windows Store and Apps as well as PC Settings not to function, people keep doing it using the method described in this tutorial.
DO NOT RELOCATE PROGRAMDATA! YOUR WINDOWS STORE AND APPS WILL NOT WORK IF PROGRAMDATA IS MOVED FROM ITS DEFAULT LOCATION.
I highlighted the important part. Other than a new clean install, I do not know how you can exit the Audit Mode.
