Summary: This article outlines methods to fix system file corruption and data inaccessibility issues in Windows. It discusses using built-in tools like Check Disk and the System File Checker (SFC) utility. It provides step-by-step instructions for running SFC and explains how to manually replace corrupt files if needed. Additionally, it suggests using third-party tools like Kernel for Windows Data Recovery for data recovery in cases of Windows corruption or formatting. The tool efficiently scans both logical and physical drives, offering a comprehensive preview of recovered items for selective saving.

Data stored in Windows may become unreachable for a variety of reasons. Surprisingly, Windows includes built-in utilities that can assist in addressing corruption problems. Check Disk (CHKDSK) is a widely used tool in this regard. Additionally, numerous third-party applications are available to aid in the recovery of data lost due to Windows corruption. In this discussion, we will explore how to rectify system file issues using the System File Checker (SFC), a Windows utility.

How to Repair System Files Using System File Checker (SFC) Tool?

When the Windows Operating System encounters a missing or corrupted Windows Resource Protection (WRP) file, it may exhibit unusual behavior. To address this issue, you can utilize the System File Checker utility, which is designed to pinpoint problems with Windows system files and facilitate their restoration. Following a system file scan, this tool replaces any damaged files with a cached copy of the original. Here’s how to go about it:

  1. Run an elevated command prompt.Run an elevated command prompt
  2. Type sfc /scannow and press ENTER.Type sfc orscannowNote: If the error message ‘Windows Resource Protection could not perform the requested operation’ appears, do scanning in the Safe Mode, and verify that the folders PendingDeletes and PendingRenames exist in WinSxS\Temp (in Windows OS folder).
  3. When the verification is complete, check the message.check the messageIf missing or corrupt system files are not detected, it displays the message— ‘Windows Resource Protection did not find any integrity violations.’

When it identifies missing or corrupted system files, it makes an attempt to resolve the problem, records the specifics in the CBS logs, and exhibits one of the ensuing messages:

If there are missing/corrupt system files, and the tool could repair them:

‘Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log.’

If there are missing/corrupt system files, and the tool could not repair them:

‘Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log.’

Note: To see the details of missing/corrupt system files, copy the Sfc details from the log to a text file using ‘Findstr’ command (in the elevated command prompt).

How to fix the missing/corrupt system file issue manually?

When the software is not able to fix the issue (the second case mentioned in the previous step), one can manually replace the corrupt file.

Note: You can identify the whereabouts of the corrupted file by examining the Sfc details files. You can obtain a healthy copy of the same file from another computer that is running the same version of Windows.
