有的用戶可能就會在更新升級自己版本系統的時候遇到一些無法解決的問題。對于win101909更新升級出現錯誤0x800f0986的情況，小編覺得我們可以先對故障進行初步排除，然后針對自己的問題方向來進行詳細的解決即可。

方法一：

“干凈啟動”，排除第三方軟體的影響：

1、停止非核心的程序運作（包括第三方殺毒、優化軟體）

2、情況允許的話，卸載設備中的第三方殺毒、管家、優化軟件

3、同時按“Windows 徽標鍵+R”，輸入：msconfig，按回車(Enter)

4、點擊“服務”>“隱藏所有 Microsoft 服務”>“全部禁用”（若您啟用了指紋識別功能，請不要關閉相關服務）

5、啟動“任務管理器”，點擊啟動選項卡，將所有啟動項都禁用

6、重啟設備

方法二：

自動系統掃描：

1、右鍵點擊任務欄上的Windows圖標，選擇“Microsoft Powershell(管理員)”

2、逐一輸入以下指令：

Dism /Online /Cleanup-Image /CheckHealth，按回車

Dism /Online /Cleanup-Image /ScanHealth，按回車

Dism /Online /Cleanup-Image /RestoreHealth，按回車

sfc /scannow，按回車

3、最后重啟電腦即可。

4、如果出現”有一些文件無法修復“的回報，重復步驟1-3幾次。

方法三：

手動注冊Windows Update組件：

1、同時按“Win+X”鍵，點選“Windows PowerShell(管理員)”

2、拷貝下方的程序碼到剛打開的PowerShell里面，按回車

3、忽略紅字錯誤，重啟電腦。

4、運行Windows Update
