目前正在玩爐石傳說《冠軍的試煉》，今天偶然碰到戰網問題：一直”正在啓動戰網“
嘗試了官方論壇的各種方法，如下：
1、請確保已開啓Secondary Logon服務；
2、請嘗試刪除Battle.net文件夾；
3、關閉後臺應用程序/防火牆；
4、安全模式下安裝；
5、優化網絡連接；
6、更新Adobe Flash Play；
7、清理註冊表（嘗試通過其他工具對註冊表冗餘項進行清理）。
而且戰網客戶端無法卸載和刪除，便手動刪除”戰網客戶端目錄“和”配置目錄（通常爲C:\Users\application Data\battle.net和Blizzard entertainment)“
然後嘗試重新安裝或者卸載戰網，依然無限讀進度條。
以下是我的解決方法（已成功解決）：
1）重啓系統，進入”帶網絡連接的安全模式“
2）下載最新的戰網客戶端安裝程序，並運行安裝程序
3）安裝出錯，報錯內容”BLZBNTBTS0000005D“
5）參照4中的鏈接，嘗試修復”Secondary Logon“服務，（我的服務是可以正常啓動的，但還是有問題）。修復過程爲：新建任意名字後綴爲.reg的文件，複製粘貼以下內容，並執行：
Windows Registry Editor Version 5.00

6）由於“Secondary Logon”服務在安全模式下無法啓動，那麼這時重啓電腦，正常進入WINDOWS，再次運行戰網
7）經過本人測試，戰網順利啓動，並未無限讀進度條，大功告成
總結：
我認爲這個問題和微軟的"Secondary Logon"服務有關，和暴雪關係不大。另外，有人嘗試卸載驅動精靈也解決了問題。5C和5D這個問題即便在官方的技術支持論壇也未給出很好的解決辦法，希望這篇文章能幫助到小夥伴們。
