VC++ 修改 Windows 操作系统网卡设备显示名称（修改网卡名）需要管理员权限

源代码：（一）

bool SetInterfaceName(int interface_index, const std::string& interface_name) noexcept{if (interface_index < 0 || interface_name.empty()){return false;}SYSTEM_WINDOWS_COM_INITIALIZED WINDOWS_COM_INITIALIZED;_bstr_t bstr_interface_name = interface_name.data();return RenameAdapterByIndexWMI(interface_index, bstr_interface_name.GetBSTR());}
