Disable Protected Mode Reader 11

Question

All,
I have found articles on Adobe's website about disabling protected mode -
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\11.0\FeatureLockDown]
"bProtectedMode"=dword:00000000
[HKCU\Software\Adobe\Acrobat Reader\11\Priviledged]
"bProtectedMode"=dword:00000000
With both these settings turned on when you start up adobe and view edit > preferences it displays protected mode as being disabled however if I open task manager then open adobe reader I can see 1 instance of AcroRD32.exe - when I then open a PDF file via file > open browser to a PDF file I can see another 2 instances of AcroRD32.exe inside task manager. I thought this behavior was down to PM being enabled as it would spawn multiple instances of this to ensure it runs in sandboxing mode? The problem I have is we use an application inhouse which whitelist's only approved .dll's and .exe's and because Reader continues to spawn multiple instances of Reader even with these registry settings enabled I continue to hit issues getting Reader to work with my whitelist application.
Is there a way that when you open Reader it will only ever open 1 instance of AcroRD32.exe or is the behavior I am seeing by design even with Protected Mode disabled?
Thanks
