如何判断当前操作系统是Windows 8？

[liuli7786]

CString getSystemName()
{
	SYSTEM_INFO info;    //用SYSTEM_INFO结构判断64位AMD处理器 
	GetSystemInfo(&info);//调用GetSystemInfo函数填充结构 
	OSVERSIONINFOEX os; 
	os.dwOSVersionInfoSize=sizeof(OSVERSIONINFOEX);   
	if(GetVersionEx((OSVERSIONINFO *)&os))                  
	{ 
		CString vname; 
		//下面根据版本信息判断操作系统名称 
		switch(os.dwMajorVersion)
		{                        //判断主版本号 
			case 4: 
				switch(os.dwMinorVersion)
				{                //判断次版本号 
				case 0: 
					if(os.dwPlatformId==VER_PLATFORM_WIN32_NT) 
						vname=_T("Microsoft Windows NT 4.0");                //1996年7月发布 
					else if(os.dwPlatformId==VER_PLATFORM_WIN32_WINDOWS) 
						vname=_T("Microsoft Windows 95"); 
					break; 
				case 10: 
					vname=_T("Microsoft Windows 98"); 
					break; 
				case 90: 
					vname=_T("Microsoft Windows Me"); 
					break; 
		        } 
				break; 
			case 5: 
				switch(os.dwMinorVersion)
				{               //再比较dwMinorVersion的值 
				case 0: 
					vname=_T("Microsoft Windows 2000");                    //1999年12月发布 
					break; 
				case 1: 
					vname=_T("Microsoft Windows XP");                    //2001年8月发布 
					break; 
				case 2: 
					if(os.wProductType==VER_NT_WORKSTATION && 
						info.wProcessorArchitecture==PROCESSOR_ARCHITECTURE_AMD64)
						vname=_T("Microsoft Windows XP Professional x64 Edition"); 
					else if(GetSystemMetrics(SM_SERVERR2)==0) 
						vname=_T("Microsoft Windows Server 2003");        //2003年3月发布 
					else if(GetSystemMetrics(SM_SERVERR2)!=0) 
						vname=_T("Microsoft Windows Server 2003 R2"); 
					break; 
				} 
				break; 
			case 6: 
				switch(os.dwMinorVersion)
				{ 
				case 0: 
					if(os.wProductType==VER_NT_WORKSTATION)
						vname=_T("Microsoft Windows Vista"); 
					else 
						vname=_T("Microsoft Windows Server 2008");          //服务器版本 
					break; 
				case 1: 
					if(os.wProductType==VER_NT_WORKSTATION) 
						vname=_T("Microsoft Windows 7"); 
					else 
						vname=_T("Microsoft Windows Server 2008 R2"); 
					break; 
				} 
				break; 
			default: 
				vname=_T("未知操作系统"); 
		} 
		return vname; 
	} 
	else 
		return _T("");
} 

网上找了一个，却发现没有Windows 8的判断，不知哪位大侠知道？

要利用好MSDN的官方文档资源，一切都会有说明的。http://msdn.microsoft.com/en-us/library/windows/desktop/ms724833%28v=vs.85%29.aspx

如果读注册表其实是很简单的 打开路径HKEY_LOCAL_MACHINE "Software\\Microsoft\\Windows NT\\CurrentVersion" 读"ProductName"就可以了

6.2是Windows8 case 6: switch(os.dwMinorVersion) { case 0: if(os.wProductType==VER_NT_WORKSTATION) vname=_T("Microsoft Windows Vista"); else vname=_T("Microsoft Windows Server 2008"); //服务器版本 break; case 1: if(os.wProductType==VER_NT_WORKSTATION) vname=_T("Microsoft Windows 7"); else vname=_T("Microsoft Windows Server 2008 R2"); break; case 2: if(os.wProductType==VER_NT_WORKSTATION) vname=_T("Microsoft Windows 8"); else break; }
