安装完mysql5.7.12后想要stop或者restart都会出现以上信息。

解决办法如下：

right click on MySQL Notifier -> Actions -> Manage Monitored Items

highlight the MySQL56 entry and click the delete button -> windows service

click the add button, scroll down the list till you find MySQL56, hilight it and click ok

you can now close the menu and you should be able to start/restart/stop your server as before
