Apache端口为80和443

Question

11:05:46 AM  [Apache]   Problem detected!
11:05:46 AM  [Apache]   Port 80 in use by "Unable to open process" with PID 6476!
11:05:46 AM  [Apache]   Apache WILL NOT start without the configured ports free!
11:05:46 AM  [Apache]   You need to uninstall/disable/reconfigure the blocking application
11:05:46 AM  [Apache]   or reconfigure Apache and the Control Panel to listen on a different port
11:05:46 AM  [Apache]   Problem detected!
11:05:46 AM  [Apache]   Port 443 in use by "Unable to open process" with PID 6476!
11:05:46 AM  [Apache]   Apache WILL NOT start without the configured ports free!
11:05:46 AM  [Apache]   You need to uninstall/disable/reconfigure the blocking application
11:05:46 AM  [Apache]   or reconfigure Apache and the Control Panel to listen on a different port

这是我从xamppp控制面板获得的错误，但这是我的Skype的打印屏幕

它显示我已经取消选中80和433的端口

如何解决此问题。
