javascript呼叫window.open開啟網站的時候，IE瀏覽器下報錯：已經規劃系統關機，提示如圖：
百度找了一下都是莫名其妙的自動好了，可以查看這個帖子：詭異的JS，已經計劃系統關機錯誤。
於是改用Google搜尋相關英文內容，serverfault.com上也有人碰到過這個問題，滿意答案還比較可靠：IE8 script error 800704a6?
The only information I've been able to find on this error is from
Josh Poley's MSDN blog.（這篇msdn上的文章已經不存在）
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.
主要說的是系統更新或安裝過相關的軟體或補丁，需要重啟動後才能生效。所以上面那篇csdn的這個錯誤也是解決得莫名其妙了，應該是重新啟動過電腦。
