原英文标题：Windows 10 not connect to wifi automatically when an ethernet connection is present
这个问题可能已经有了解决方案，但这里有一个对笔者有效的、较少依赖硬件的解决方案，使用 RegEdit 和组策略。完全披露，笔者通过在 Google 上搜索该问题找到了此方法，来源是 https://appuals.com/best-fix-windows-10-will-not-connect-to-wifi-automatically/。该网站署名 Kevin Arrows，他自称是一名拥有超过 10 年经验的 MCTS（Microsoft Certified Technology Specialist）认证专家。笔者在 Dell 笔记本电脑上尝试了此方法，效果很好。
通过注册表编辑器编辑或创建组策略
按住 Windows 键并按 R。在运行对话框中，输入 regedit 并点击确定。在注册表编辑器中导航到以下路径，
HKLM\Software\Policies\Microsoft\Windows\WcmSvc\
查看 GroupPolicy 子键是否存在，如果不存在，在选中 WcmSvc 的情况下，右键点击 WcmSvc 并选择“新建 -> 键”，将其命名为 GroupPolicy，然后点击 GroupPolicy，在右侧窗格中（右键点击）选择“新建 -> DWORD (32 位) 值”，创建一个名为 fMinimizeConnections 的值，然后点击确定。现在，重启并测试。
此策略允许你自动连接到无线网络，即使插入了 LAN 网线，并且适用于 Windows 8/8.1 和 10。

This may have been solved already, but here is a less hardware driven solution that worked for me using RegEdit and Group Policy. Full disclosure, I found this by Googling the issue on the web at https://appuals.com/best-fix-windows-10-will-not-connect-to-wifi-automatically/. The site is id'd as from Kevin Arrows, who says he is a certified MCTS (Microsoft Certified Technology Specialist) with over 10 years of experience. I tried this on my Dell laptop and it worked great.
Edit or Create Group Policy via Registry Editor
Hold the Windows Key and Press R. In the run dialog, type regedit and click OK. Navigate to the following path in Registry Editor,
HKLM\Software\Policies\Microsoft\Windows\WcmSvc\
See if the GroupPolicy subkey exists, if not with WcmSvc highlighted, right click on WcmSvc and Choose New -> Key and name it GroupPolicy, then click GroupPolicy and then in the right pane, (right-click) and choose New -> DWORD (32-bit) and create value, name it as fMinimizeConnections and Click OK. Now, reboot and test.
This policy allows you to connect automatically to wireless network, even with a LAN plugged in and works on both Windows 8/8.1 and 10.
