今天下载安装MySQL 8.0.28后，打开Workbench，简单看一下Server status，一直提示：Target host is configured as Windows, but seems to be a different OS. Please review the connection settings

然后按照提示提示，在正确设置Installation type，并test connection正常后，问题依然存在。网络搜索下发现这是一个BUG，最近的几个版本都有，是Workbench在获取系统信息因编码问题导致的，解决方案很简单。

打开文件 C:\Program Files\MySQL\MySQL Workbench 8.0\workbench\os_utils.py （具体路径看你的MySQL安装路径）中第356将

process = subprocess.Popen(command, stdin = subprocess.PIPE, encoding=‘utf-8’, stdout = subprocess.PIPE, stderr = subprocess.STDOUT, shell=True)

修改为

process = subprocess.Popen(command, stdin = subprocess.PIPE, encoding=‘ansi’, stdout = subprocess.PIPE, stderr = subprocess.STDOUT, shell=True)
