我正在使用Windows 8.1 x64，版本6.3.9600.16384，并使用具有管理员权限的命令提示符。

sfc /scannow

返回：

...found corrupt files but was unable to fix some of them.

和

dism /online /cleanup-image /restorehealth

返回：

Error: 0x800f0906
The source files could not be downloaded.

（由于缺少这些文件，因此Windows Update Service无法启动。）

也尝试过

dism /online /cleanup-image /restorehealth /source:wim:F:\sources\install.wim:1 /limitaccess

并返回：

Version: 6.3.9600.16384
Image Version: 6.3.9600.16384
Error: 0x800f081f
The source files could not be found.

我安装了图像，然后从那里尝试。

dism /mount-image /imagefile:F:\sources\install.wim /index:1 /mountdir:C:\offline

dism /online /cleanup-image /restoreHealth /source:c:\offline /limitaccess

还返回：

Error: 0x800f081f

如何修复损坏的系统文件？

我可以告诉DISM使用Windows安装光盘作为源吗？

过滤细节

运行sfc /scannow会产生一个CBS.log报告文件（通常在中找到C:\Windows\Logs\CBS），其中包含大量信息。为了获得多汁的位，请打开命令提示符，然后执行以下命令：

findstr /i /c:"[SR]" "%windir%\Logs\CBS\CBS.log" | findstr /i /v /c:"verify" > "%userprofile%\Desktop\sfc.txt"

上面的命令将：

1. 获取原始文件中包含的所有行，这些行[SR]用于跟踪修复尝试。

2. 删除verify上一步中包含的所有行，以进一步减少混乱。

3. 将结果写入sfc.txt文件中以供以后分析。

在这种情况下，这将是结果文件：

找出问题

检查文件后，您可以看到系统文件检查器试图修复3个组件，但是失败了：

2014-02-19 17:23:00, Info                  CSI    00000979 [SR] Cannot repair member file [l:22{11}]"Generic.xbf" of Microsoft-Windows-Camera-MediaViewerDistributed-MediaShared, Version = 6.3.9600.16485, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral in the store, file is missing

每个条目都遵循以下粗略方案：

• Cannot repair member file [...]"Generic.xbf"
  需要修复的文件。

• of Microsoft-Windows-Camera-LockScreenCamera-Main,
  文件所属的软件包的名称。

• Version = 6.3.9600.16485,
  文件版本（主要，次要，内部版本和修订版）。

• pA = PROCESSOR_ARCHITECTURE_AMD64 (9),
  目标处理器架构。

• Culture neutral, [...],
  如果是本地语言，则为 中性或相关的文化名称。

• file is missing
  原因文件需要修复。

Generic.xbf缺少三个文件。此外，它们所有人都共享以下信息：

2014-02-19 17:23:00, Info                  CSI    0000097b [SR] This component was referenced by [l:154{77}]"Package_1_for_KB2914218~31bf3856ad364e35~amd64~~6.3.1.3.2914218-1_neutral_GDR"

这意味着该文件包含在KB2914218 Windows更新中。

手动维修

1. 获取KB2914218更新程序包。

2. .msu使用7-Zip提取以原始文件命名的文件夹中的下载文件（例如Windows8.1-KB2914218-x64）。

3. 以管理员身份打开命令提示符，并使用以下命令导航到实际文件夹：

   cd /d "X:\Whatever\Windows8.1-KB2914218-x64"
   

4. 展开包含当前目录中更新文件的文件柜档案：

   expand Windows8.1-KB2914218-x64.cab -f:* %cd%
   

5. 每个软件包都有一个关联的.manifest文件，其中列出了捆绑的文件。为了确定每个文件的存储位置，请通过替换packagaName并fileName.ext使用实际值来运行以下命令：

   for /f "delims=" %A in ('"findstr /i /m /c:"packageName" *.manifest"') do @for /f "delims=" %B in ('"findstr /i /m /c:"fileName.ext" %A"') do @echo %~nB;fileName.ext>>fixes.txt
   

   例如：

   for /f "delims=" %A in ('"findstr /i /m /c:"Microsoft-Windows-Camera-LockScreenCamera-Main" *.manifest"') do @for /f "delims=" %B in ('"findstr /i /m /c:"Generic.xbf" %A"') do @echo %~nB;Generic.xbf>>fixes.txt
   

6. 对任何其他需要修复的文件重复步骤5。

7. 取得所有权并完全控制该C:\Windows\winsxs文件夹：

   takeown /f "%windir%\winsxs" /a
   icacls "%windir%\winsxs" /grant:r *S-1-5-32-544:(OI)(CI)(F) /q
   

8. 创建任何丢失的文件夹：

   for /f "tokens=1 delims=;" %G in (fixes.txt) do @if not exist "%windir%\winsxs\%~G\" @md "%windir%\winsxs\%~G"
   

9. 完全控制所需的文件夹：

   for /f "tokens=1 delims=;" %G in (fixes.txt) do takeown /f "%windir%\winsxs\%~G" /a >nul & icacls "%windir%\winsxs\%~G" /grant:r *S-1-5-32-544:(OI)(CI)(F) /q
   

10. 恢复文件：

    for /f "tokens=1,2 delims=;" %A in (fixes.txt) do copy /y ".\%A\%B" "%windir%\winsxs\%A\%B"
    

11. 重复系统文件检查以确保问题已解决：

    sfc /scannow
