[Quick Fix] Incorrect Windows Server Technical Preview Functional Level on 2016 RTM

What’s wrong?

using Windows Server 2016 RTM (build 14393)
- Technet’s ISO: en_windows_server_2016_x64_dvd_9327751.iso
- ISO SHA1: 7e33df150cb4d1fe3503e23433a1867ddd79a6ee
- when doing Active Directory Domain Services deployment configuration using GUI
- on the Domain Controller Options page
- you may see Windows Server Technical Preview both Domain and Forest Functional Level:

How to fix it?

install KB3192366
- https://support.microsoft.com/en-us/kb/3192366
enjoy the GUI… (said no one ever)

Sidenotes:

patch fixes only GUI way and not the PowerShell cmdlet (Install-ADDSForest) to create a new AD forest
- before and after applying it, while executing Install-ADDSFforest, the new value of Forest/DomainMode argument will be still “WinTreshold” 🙁
patch doesn’t affect objectVersion attribute value of “CN=Schema,CN=Configuration,DC=domain,DC=local” which is 87 (Windows 2016)
