Windows 10 ADK 1607 is now available for download. I will update my scripts to use ADK 1607 instead of 1511. Hopefully we don’t need any hotfixes to this version.
You can download ADK 1607 from Microsoft: http://download.microsoft.com/download/9/A/E/9AE69DD5-BA93-44E0-864E-180F5E700AB4/adk/adksetup.exe
