The NL_OSVERSIONINFO_V1 structure specifies the values used to update the operatingSystemVersion and operatingSystem attributes on the client's computer account object in Active Directory on a normal (writable) DC.<31>

 typedef struct _NL_OSVERSIONINFO_V1 {
   DWORD dwOSVersionInfoSize;
   DWORD dwMajorVersion;
   DWORD dwMinorVersion;
   DWORD dwBuildNumber;
   DWORD dwPlatformId;
   wchar_t szCSDVersion[128];
   USHORT wServicePackMajor;
   USHORT wServicePackMinor;
   USHORT wSuiteMask;
   UCHAR wProductType;
   UCHAR wReserved;
 } NL_OSVERSIONINFO_V1;

dwOSVersionInfoSize: The size, in bytes, of this data structure. Set this member to sizeof(NL_OSVERSIONINFO_V1).

dwMajorVersion: The implementation-specific major version number of the operating system.<32>

dwMinorVersion: The implementation-specific minor version number of the operating system.<33>

dwBuildNumber: The build number of the operating system.

dwPlatformId: The operating system platform. This member can be 0x00000002.

szCSDVersion: A null-terminated string, such as "Service Pack 3", that indicates the latest service pack installed on the system. If no service pack has been installed, the string is empty.
