推荐答案

一旦微控制器检测到按下按钮，它就会发送一个关闭消息给您的应用程序在PC上运行。反过来，该应用程序可以关闭Windows调用 InitiateSystemShutdownEx [ ^ ]（请参阅备注部分）

Once the microcontroller detects the button press, it can send a 'shutdown' message to the your application running on the PC. The application, in turn, can shutdown Windows calling InitiateSystemShutdownEx[^] (please see the Remarks section)
