javascript调用window.open打开网站的时候，IE浏览器下报错：已经计划系统关机，提示如图：
百度找了下都是莫名其妙的自动好了，可以查看这个帖子：诡异的JS，已经计划系统关机错误。
于是改用谷歌搜索相关英文内容，serverfault.com上也有人碰到过这个问题，满意答案还比较靠谱：IE8 script error 800704a6"codetitle">复制代码 代码如下:
The only information I've been able to find on this error is from Josh Poley's MSDN blog.（这篇msdn上的文章已经不存在）
1190 0x800704A6 A system shutdown has already been scheduled. ERROR_SHUTDOWN_IS_SCHEDULED
However, the message implies that you get this when trying to schedule a shutdown. The only thing I can think of is that an installation/Windows update is waiting for a reboot.
You say that you can't see updates in Add/Remove programs - have you checked the "Show updates" option is checked?
Other posts that mention this error are similar in nature to yours.
主要说的是系统更新或者安装过相关的软件或者补丁，需要重启动后才能生效。所以上面那篇csdn的这个错误也是解决得莫名其妙了，应该是重启过电脑。
