Windows 8.1 64位系統，Microsoft office 2013使用時出現提示：“Microsoft Office 無法驗證此應用程序的許可證。修復嘗試失敗或者已被取消。Microsoft Office現在將退出。”苦逼的小編恰好就碰到了這個問題，索性還是比較容易解決的，現在把解決方案分享給大家。
工具/原料
出現錯誤提示的電腦
分析原因
先探究一下原因：對電腦註冊表的清理、優化掉一些服務、優化開機速度等一些操作以後，就出現了“Microsoft Office 無法驗證此應用程序的許可證。修復嘗試失敗或者已被取消。Microsoft Office現在將退出。”的錯誤提示。
這個時候不要盲目重裝office軟件，這樣效率太低。萬一還是老樣子，豈不是要考慮重新安裝操作系統，或者是重新購買一臺電腦(⊙﹏⊙)b
解決方案
打開"服務"窗口：services.msc（搜索一下，或者Win+x→運行都可以打開這個窗口）
找到”software prtection服務“，office出現錯誤提示的時候，這個服務是禁止狀態。如果直接能夠啟動，那就可以把這個問題解決了。
小編的電腦通過服務窗口，不能直接啟動software prtection服務，只能通過修改註冊表的方式解決。打開註冊表：
找到這個目錄：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\sppsvc，這個看起來有點複雜了，不好下手啊。
還是直接雙擊一下注冊表文件比較方便。把一下代碼複製到一個文本文檔裡，把文件名改為“software prtection服務.reg”，雙擊這個.reg文件，即可修復software prtection服務的註冊表。（或者通過百度網盤下載：）

測試一下office是否恢復正常使用了
注意事項
如何找不到software prtection服務，就直接通過修復註冊表解決吧
