Windows 10 WMI / CIM DHCP Information Wrong?

[Karl_Amber]

I was automating some network functionality & reporting w/ PowerShell and needed to evaluate the DHCP Lease time values. Using WMI / CIM - the Win32_NetworkAdapterConfiguration class returns incorrect data.

Using IP Config returns the correct data.

I can validate that this is occurring on multiple Windows 10 machines.

Is there a known fix for this?
