Output OS version/Service pack info

[Pyramus]

What's the best way to get this information?

I've found the answer to this in using GetVersionEx which uses the OSVERSIONINFOEX structure.

But what I don't understand is some of the members of the structure don't seem to be defined, contradicting what MSDN says. On MSDN the structure is

typedef struct _OSVERSIONINFOEX {
  DWORD dwOSVersionInfoSize;
  DWORD dwMajorVersion;
  DWORD dwMinorVersion;
  DWORD dwBuildNumber;
  DWORD dwPlatformId;
  TCHAR szCSDVersion[ 128 ];
  WORD wServicePackMajor;
  WORD wServicePackMinor;
  WORD wSuiteMask;
  BYTE wProductType;
  BYTE wReserved;
} OSVERSIONINFOEX, *POSVERSIONINFOEX, *LPOSVERSIONINFOEX;

But, for example, wProductType does not exist when I try this. Has anyone found this?

MSDN shows that the GetVersionEx function really takes an OSVERSIONINFO structure, not an OSVERSIONINFOEX structure.
VerifyVersionInfo does take the OSVERSIONINFOEX structure, however. Did you look at MSDN's sample : "getting the system version"?
