獲取Windows系統版本

【1】說明

1、由於GetVersionEx函數在Windows 8.1版本之後,返回的結果全部是6.2,這函數被微軟動了手腳的,但是實際上可以利用額外添加一個manifest文件指示兼容新版本.

(參看文章:http://blog.csdn.net/k1988/article/details/47614529)

2、GetVersionEx函數還有一個問題,就是當使用兼容模式打開程序時,它返回的是兼容模式下的系統版本號.

由於以上這兩個問題,建議用Version Helper系列的函數或使用直接內核的函數獲取系統版本信息.

(文章：https://msdn.microsoft.com/en-us/library/windows/desktop/dn424972(v=vs.85).aspx)

這裏直接使用ntdll.dll裏的內核函數,獲取系統版本信息.

//獲取系統版本號
#define SYSTEM_VERSION_UNKNOW _T("未知的操作系統")
BOOL GetSystemVersion(LPWSTR version, DWORD lenth)
{
	BOOL Wow64;
	SYSTEM_INFO info;
	//判斷是否是在64位系統模擬層上運行
	if (!IsWow64Process(GetCurrentProcess(), &Wow64))
		return FALSE;
	//獲取CPU信息
	if (Wow64)
		GetNativeSystemInfo(&info);
	else
		GetSystemInfo(&info);
	//定義變量
	typedef LONG(__stdcall *fnRtlGetVersion)(PRTL_OSVERSIONINFOW lpVersionInformation);
	fnRtlGetVersion pRtlGetVersion;
	HMODULE hNtdll;
	LONG ntStatus;
	RTL_OSVERSIONINFOEXW os;
	//獲取函數
	hNtdll = GetModuleHandle(_T("ntdll.dll"));
	if (hNtdll == NULL)
		return FALSE;
	pRtlGetVersion = (fnRtlGetVersion)GetProcAddress(hNtdll, "RtlGetVersion");
	if (pRtlGetVersion == NULL)

	//獲取系統相關信息
	os.dwOSVersionInfoSize = sizeof(RTL_OSVERSIONINFOEXW);
