OSVERSIONINFO OsVersionInfo;//包含操作系统版本信息的数据结构
OsVersionInfo.dwOSVersionInfoSize= sizeof(OSVERSIONINFO);
GetVersionEx(&OsVersionInfo);//获取操作系统版本信息

typedef struct _OSVERSIONINFO{
DWORD dwOSVersionInfoSize;
DWORD dwMajorVersion;
DWORD dwMinorVersion;
DWORD dwBuildNumber;
DWORD dwPlatformId;
TCHAR szCSDVersion[ 128 ];
} OSVERSIONINFO;
其中，dwPlatformId
Identifies the operating system platform. This member can be one of the following values: Value Platform
VER_PLATFORM_WIN32s Win32s on Windows 3.1.
VER_PLATFORM_WIN32_WINDOWS Win32 on Windows 95 or Windows 98.
For Windows 95, dwMinorVersion is zero.

For Windows 98, dwMinorVersion is greater than zero.

VER_PLATFORM_WIN32_NT Win32 on Windows NT.
