Apache在XAMPP（Windows 7）上启动后意外关闭

请注意，我是个新手，如果这只是一个愚蠢的错误，请容忍我

我的Win7笔记本电脑上有XAMPP，没有IIS，没有额外的MySQL内容。但是，每当我为apache模块单击start时，就会出现这种情况

Skype和VMWare已断开连接，错误日志或Windows事件查看器中没有任何内容，据我所知，端口80是免费的

任何建议都是非常受欢迎的

非常感谢

编辑：谢谢你的回答。事实证明，微软WebMatrix发布的Web部署服务是罪魁祸首。非常感谢

从错误日志中可以明显看出端口80已打开

Open a CMD prompt and type in command: net stop was /y

Run Dialog Box (press keys Win+R) .. then type: services.msc

然后我向下滚动到：World Wide Web Publishing Service双击它并单击STOP（如果此服务状态为Started）
