SMS Provider Locations Do Not Match - Problem installing SCCM 2012 R2 CU4

Question

I have an SCCM 2012R2 CU1 site that has been upgraded from SCCM 2012 non-SP1, so I have gone from 2012 to 2012SP1 through CU5 and then to R2 and then to CU1.
Over the course of the life of this site, which has more than 10k clients and 10 Site Systems, we have installed roles, removed roles, moved roles and removed Site Systems.
I have also installed and removed SMS providers . . . which is where my issues begin.
The site properties in the console list 6 SMS Providers and even lists an SMS provider on a server that was retired and is no longer a Site System.  When I query WMI using the following VBS script it only returns the *ACTUAL* SMS Provider locations,
2 of the 6 listed in the GUI.
On Error Resume Next
Const ForReading = 1, ForWriting = 2, ForAppending = 8
strComputer = "." 
Set oFS = CreateObject("Scripting.FileSystemObject")
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\sms")
If Err.Number <> 0 Then
WScript.Echo "Cannot connect to WMI"
WScript.Echo vbTab & "Error " & Err.Number & " - " & Err.Description
End If
Set oLog = oFS.OpenTextFile("C:\Temp\SMS_ProvList.log",ForAppending, True)
If Err.Number <> 0 Then
WScript.Echo "Could not create output file"
WScript.Echo vbTab & "Error " & Err.Number & " - " & Err.Description
End If
Set colItems = objWMIService.ExecQuery("SELECT * FROM SMS_ProviderLocation",,48)
count = 0
For Each objItem in colItems
    count = count + 1
    oLog.WriteLine "-----------------------------------"
    oLog.WriteLine Now()
    oLog.WriteLine "Provider instance " & count &  " : " & objItem.Machine
    oLog.WriteLine "NamespacePath : " & objItem.NamespacePath     
    oLog.WriteLine ""
Next
I have a test environment which has also gone through some growth over its lifetime and has had the same changes to SMS Providers made.  When I first attempted to install SCCM 2012 R2 CU4 in this test environment the installer continually failed the
prerequisite checker when querying the CU level of the SMS Providers.  The only way that I could get past that issue was by running a site maintenance task via the CM installer and installing an SMS Provider at the location that had previously been an
SMS Provider but I had uninstalled that role.
I do not want to have to do that in my production environment, and would not even be able to do so if I wanted as I have retired one of the servers listed and cannot re-provision that machine.
Any CM12 gurus out there with suggestions?  This strikes me as a standard MS problem when having multiple development teams working on a product/update and not having a standard location to check for configuration information (This is exactly the problem
when configuring DNS suffixes via GPO and not manually setting the GUI to match).
Thanks!

Answer 1

The issue I have is that I cannot find the WMI class that holds the SMS Providers that are returned by the GUI.
I actually engaged MS Premier for a SCCM 2012 RAAS about 2 years ago and that was when the discrepancy first reared it's head.  The support person that I worked with couldn't give me a way of cleaning those entries at that point which is when I started
logging the locations to be sure that my maintenance task was really installing or removing the SMS Providers.
