windows查看端口占用，通过端口找进程号（查找进程号），通过进程号定位应用名（查找应用）（netstat、tasklist）

通过端口号查看进程号netstat
在Windows系统中，可以使用 netstat 命令来查看端口的占用情况。以下是具体的步骤：
-
打开命令提示符（CMD）：按Win+R组合键打开运行对话框，输入cmd并按Enter键。
-
在命令提示符中输入以下命令，并按Enter键：
netstat -ano
这个命令会列出所有活动的TCP连接以及监听的UDP端口，并显示相关进程的PID（进程ID）。
如果你想查找特定的端口（例如123），可以使用以下命令：
netstat -ano | findstr "123"
以上命令会查找并显示所有使用了123端口的进程。
通过进程号定位应用程序tasklist
如果你已经知道某个端口被占用，但你需要找出是哪个进程占用的，你可以记下上述命令返回结果中的PID，然后使用以下命令查找该PID对应的进程：
tasklist | findstr "PID"
其中，"PID"需要替换为你实际记录下的进程ID号。
也可以通过windows任务管理器进程号定位应用程序：
