You can use the GetVersion() API from the SDK.  Or the GetVersionEx() API.  I prefer the GetVersionEx() API when I want richer amounts of information:

//  code to get OS environment
//  using GetVersionEx


ZeroMemory(&osv, sizeof(OSVERSIONINFO));

//  always set this before the call!
osv.dwOSVersionInfoSize =

if (GetVersionEx(&osv))
else // an error occured
  //  call GetLastError() to get info

//  code to get OS using GetVersion()

DWORD dwVer = GetVersion();
BOOL bNT = dwVer < 0x80000000;
