The SO answer links to the KNOWNFOLDERID docs; the relevant entry 
specifically is at

http://msdn.microsoft.com/en-us/library/windows/desktop/dd378457.aspx#FOLDERID_ProgramData

which gives the default path as,

%ALLUSERSPROFILE% (%ProgramData%, %SystemDrive%\ProgramData)

checking on my local windows 7 install gives:

C:\>echo %ALLUSERSPROFILE%
C:\ProgramData

C:\>echo %ProgramData%
C:\ProgramData
