So it appears that (regardless of patch version currently) Windows 10 release 1803 has a string value mis-match between the data in registry property "HKLM:\Software\Microsoft\Windows NT\CurrentVersion".ProductName and "HKLM:\Software\Wow6432Node\Microsoft\Windows NT\Currentversion".ProductName
This device has a Windows 10 Pro KMS key. WMI reports Windows 10 Pro, Get-WindowsEdition reports Windows 10 Pro, Winver.exe reports Windows 10 Pro, System Information/About reports Windows 10 Pro.
Any 32 bit application or management client querying the 32-bit registry reports Windows 10 Enterprise. Check the keys, the native registry has "Windows 10 Pro" as the string data and the wow6432node has "Windows 10 Enterprise"
This could be a costly mistake....may want to think about fixing that in an upcoming patch.
