Windows Update 80246008錯誤的解法 ( BITS, COM+ Event System )

本篇文章為轉貼文章，如要轉貼，請經過原始創作人之同意。

最近遇到這個問題，也花了一些時間在解，記錄一下過程。

【症狀】

    Windows Update無法更新，報錯代碼 80246008

【解法】

    google一下發現可能的原因就是BITS(Background Intelligent Transfer Service)服務沒有起來，而這個服務有相依性依存在 COM+ Event System 和 Remote Procedure Call 這兩個服務上面，檢查了一下發現我的COM+ Event System竟然消失了！難怪BITS怎麼樣也起不來。


找到幾個鄉民說的方法，但只有註冊檔這個對我有效

32bit系統請copy這一段，然後存成.reg檔案，執行後重開機即可

這樣COM+ Event System就會出現並復活，但還是要手動把他叫起來，然後再把BITS叫起來。

大工告成！　可喜可賀可喜可賀！
