"a windows service with the name MYSQL already e..."的问题 安装MySQL的时候出现这个报错：a windows service with the name MYSQL already exists.
Please uninstall this service correctly or choose a different name for the new service.
 开始－－运行－－输入 regedit，删除残留的注册表信息HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services下面找到MySQL注册表信息把它整个删掉后，重装mysql成功了！   接着到regedit把注册表 HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/Eventlog/Applications/MySQLHKEY_LOCAL_MACHINE/SYSTEM/ControlSet002/Services/Eventlog/Applications/MySQLHKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Eventlog/Applications/MySQL
