如何从安装光盘修复损坏的系统文件

Question

我使用的是 Windows 8.1 x64，构建 6.3.9600.16384，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.

（并且 Windows 更新服务无法启动，因为这些文件丢失。）

也试过

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，并从那里开始尝试。

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

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

也返回：

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？

Answer 1

过滤细节

运行sfc /scannow将生成一个包含大量信息的CBS.log报告文件（通常在 中找到C:\Windows\Logs\CBS）。为了获得多汁的位，打开命令提示符，并执行以下命令：

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. 获取包含 的原始文件中的所有行[SR]，这些行是跟踪修复尝试的行。

2. 删除包含verify我们在上一步中得到的所有行，以进一步减少混乱。

3. 将结果写入sfc.txt文件以供以后分析。

在这种情况下，这将是结果文件：

确定问题

检查文件，您可以看到系统文件检查器尝试修复 3 个组件，但失败了：

每个条目都遵循这个粗略的方案：

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

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

• Version = 6.3.9600.16485,
  文件版本（主要版本、次要版本、构建版本和修订版本）。

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

• Culture neutral, [...],
  中性或相关的文化名称（如果已本地化）。

• file is missing
  需要修复文件的原因。

Generic.xbf缺少三个文件。此外，他们所有人都分享了以下信息：

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。

人工维修

1. 获取KB2914218更新包。

2. .msu使用7-Zip将下载的文件解压缩到以原始文件命名的文件夹中（例如Windows8.1-KB2914218-x64）。

3. 以管理员身份打开命令提示符，然后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cabinet 存档：

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

5. 每个包都有一个关联.manifest文件，其中列出了捆绑文件。为了确定每个文件的存储位置，请通过替换packagaName和fileName.ext使用实际值运行以下命令：

   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. 对需要修复的任何其他文件重复步骤 5。

7. 取得C:\Windows\winsxs文件夹的所有权和完全控制权：

   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修复：

    sfc /scannow
