Forest/Domain Mode = WinThreshold??

Really MSFT?

Come on… Sloppy.

-ForestMode

Specifies the forest functional level for the new forest. Supported values for this parameter can be either a valid integer or a corresponding enumerated string value. For example, to set the forest mode level to Windows Server 2008 R2, you can specify either a value of 4 or Win2008R2.

The acceptable values for this parameter are:

• Windows Server 2003: 2 or Win2003
• Windows Server 2008: 3 or Win2008
• Windows Server 2008 R2: 4 or Win2008R2
• Windows Server 2012: 5 or Win2012
• Windows Server 2012 R2: 6 or Win2012R2
• Windows Server 2016: 7 or WinThreshold

The default forest functional level in Windows Server is typically the same as the version you are running. However, the default forest functional level in Windows Server 2008 R2 when you create a new forest is Windows Server 2003 or 2.
