Minor OSConfig update was published today on GitHub:
If you add CMTrace.exe to C:\Windows\System32 (by way of OSConfig OEM Folders) then you will have the OSConfig.log available for progress viewing. If it gets hidden by the Getting Ready, just press Alt+Tab to bring it to the foreground. Additionally more Samples have been added for DefaultLayouts.xml and LayoutModification.xml. Enjoy
