texlive更新问题

MathLua

中文版win10系统下安装了texlive,用tlmgr更新宏包时出现这样的警告:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LC_ALL = "zh_CN.UTF-8",
        LANG = "zh_CN.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
linux系统下有locale settings设置,win10怎么解决啊?

windows下我全默认安装。
不明楼主因，提醒，windows 不支持跨版本升级，新版需全新安装

没用过 win10 表示爱莫能助……
