使用批量文本替换工具替换掉Unity安装目录中\Editor\Data\Documentation\en\Manual\下的所有文件中的如下两个部分：
1.
<script type="text/javascript">
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-2854981-1']);
_gaq.push(['_setDomainName', 'unity3d.com']);
_gaq.push(['_trackPageview']);
(function() {
var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();
</script>
2.
