我该怎么做在 Windows 中获取 COM 端口的友好名称?

这是关于找到友好名称，但我认为您会发现它会将您指向注册表的正确区域，使用官方"机制来定位正确的密钥.

It's about finding the friendly name, but I think you'll find it points you towards the right area of the registry, using the 'official' mechanism for locating the right key.

但是，如果您更改端口分配，您还应该更新 com 端口数据库 - 请参阅:https://msdn.microsoft.com/en-us/library/ff546481.aspx

However, if you change the port assignment, you should also update the com port database - see: https://msdn.microsoft.com/en-us/library/ff546481.aspx

当我不得不做类似的事情时，我使用链接的 SO 文章中描述的机制找到了正确的设备，然后调用了 SerialDisplayAdvancedSettings((HWND)NULL, hDeviceInfo, &devInfoData);显示高级对话框并让操作系统处理繁重的工作.

When I had to do something similar, I found the right device using the mechanism described in the linked SO article, and then called SerialDisplayAdvancedSettings((HWND)NULL, hDeviceInfo, &devInfoData); to display the advanced dialog and let the OS handle the hard work.

如今，您越来越有可能遇到奇怪的非真实"串行端口(例如 USB 端口)，这些端口可能还有其他不兼容的问题，您也需要警惕.

Nowadays you're more and more likely to be encountering odd 'not real' serial ports (e.g. USB ports) which might have other incompatibilities you need to be wary of too.
