相信有很多人都在为WiFi图标消失不见而头疼，我在这里整理一下解决办法：

将一下代码复制到文本文档里：Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog]
“ServiceDll”=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,
00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,
77,00,65,00,76,00,74,00,73,00,76,00,63,00,2e,00,64,00,6c,00,6c,00,00,00
并更改后缀名为.reg，打开运行后重启即可解决问题。
