系统文件检查器或 SFC是一种系统工具，可以让用户扫描和恢复损坏的 Windows 系统文件。它与Windows 资源保护^{(Windows Resource Protection)}集成，可保护注册表项和文件夹以及关键系统文件。如果存在文件完整性问题，SFC可以修复它。但是，如果您运行它，但它无法运行或无法修复，那么这篇文章将帮助您修复它。

SFC无法在^(SFC)Windows 11/10中运行或无法运行

有时您可能需要运行SFC 两^{(SFC two)}到三次或在安全模式下运行它。如果由于某种原因，您发现系统文件检查器^{(System File Checker)}无法正常工作或无法运行或无法修复，您可以尝试修复组件存储^{(repair the Component Store)}，看看是否有帮助。

Dism /Online /Cleanup-Image /RestoreHealth

您也可以尝试在安全模式、启动时间或离线模式下运行系统文件检查器。

系统文件检查器^{(System File Checker)}无法修复损坏的成员文件

如果您遇到此问题，您将使用分叉文件手动替换损坏的文件。您必须从Windows ISO或另一台计算机中找到DLL 。记下损坏的文件路径，并将文件的新版本复制到您的计算机。

然后，通过在运行^(Run)提示符 ( Win + R ) 中键入 cmd，然后按Shift + Enter以管理员权限打开命令提示符^{(Command Prompt)}。

在命令提示符下键入以下内容，然后按 Enter。Takedown命令将授予您访问权限，以便文件可以被新文件覆盖。

takeown /f Path_And_File_Name

其中Path_And_File_Name 是损坏文件的确切位置。

执行以下命令以授予管理员对该文件的完全访问权限。

icacls命令可以显示或修改指定文件上的任意访问控制列表 ( DACL^(DACLs) )。

icacls Path_And_File_Name /GRANT ADMINISTRATORS:F

例如，键入：

icacls C:\Windows\system32\corruptfile.dll /grant administrators:F

然后用文件的已知良好副本手动替换文件：

Copy Path_And_File_Name_Of_Source_File Path_And_File_Name_Of_Destination

例如，键入：

copy E:\temp\corruptfile.dll E:\windows\system32\corruptfile.dll

如果没有其他工作，那么您可以尝试系统还原^{(System Restore)}、刷新 PC 或重置 PC^{(Refresh PC, or Reset PC)}。

我希望你能够解决这个问题。

SFC not working, will not run or could not repair corrupt file in Windows 11/10

The System File Checker or SFC is a system tool thаt can allow users tо scan for and restore corrupt Wіndows sуstem files.  It is integrated with Windows Resource Protection, which protectѕ registrу keys and folders as wеll as critiсal system files.  If there іs a file integritу issue, SFC can fix it. However, іf yоu run it, and it failѕ to run or could not repair, then this pоst will help you fіx it.

SFC not working or will not run in Windows 11/10

Sometimes you may have to run the SFC two or three times or run it in safe mode. If for some reason, you find that your System File Checker is not working or will not run or could not repair, you can try and repair the Component Store and see if it helps.

Dism /Online /Cleanup-Image /RestoreHealth

You could also try and run System File Checker in Safe Mode, Boot Time, or Offline.

Read:

• Windows Resource Protection could not perform the requested operation
• Windows Resource Protection could not perform the requested operation
• Windows Resource Protection found corrupt files but was unable to fix some of them.

System File Checker cannot repair corrupted member file

If you face this issue, you will replace the corrupt file manually with a forking file. You will have to find the DLL from Windows ISO or another computer.  Make a note of the file path which is corrupted, and copy a fresh version of the file to your computer.

Then, open Command Prompt with admin permission by typing cmd in the Run prompt (Win + R), and then pressing Shift + Enter.

Type the following in the command prompt and press enter. The Takedown command will grant you access so that the file can be overwritten by a new one.

takeown /f Path_And_File_Name

Where Path_And_File_Name is the exact location of the corrupted file.

Execute the following command to grant administrators full access to the file.

The icacls command can display or modify discretionary access control lists (DACLs) on specified files.

icacls Path_And_File_Name /GRANT ADMINISTRATORS:F

For example, type:

icacls C:\Windows\system32\corruptfile.dll /grant administrators:F

Then manually replace the file with a known good copy of the file:

Copy Path_And_File_Name_Of_Source_File Path_And_File_Name_Of_Destination

For example, type:

copy E:\temp\corruptfile.dll E:\windows\system32\corruptfile.dll

If nothing else works, then you may try a System Restore, Refresh PC, or Reset PC.

I hope you were able to resolve the issue.
