How do I repair the corrupted files found by sfc /scannow? "Windows Resource Protection found corrupt files but was unable to fix some of them."

In Windows 7, after running chkdsk C: /F /R and finding out that my hard disk has 24 KB in bad sectors (log is posted below), I decided to run Windows 7's System File Checker utility (sfc /scannow).

SFC showed the ff. message after I ran it: "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."

Since the CBS.log file is too large, I ran findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt" (as per Microsoft's KB 928228 article) to only get the log text pertaining to the corrupt files. (log is also posted below)

How do I troubleshoot and repair the corrupted files mentioned by sfc /scannow?

My OS is Windows 7, 64-bit.

(through findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt")

Note: The full log is at http://pastebin.com/raw.php?i=gTEGZmWj . I've only quoted parts of the full log below (mostly from the last part), as the full log won't fit within the character limit for questions. I've added it to serve as a preview.

Answer

The only way to fix this large amount of corrupted files in Windows 7 is to do a repair installation/Inplace upgrade.

• Insert your Windows 7 DVD or mounted a Windows 7 ISO


• Run setup.exe from the DVD/mounted ISO


• during setup select upgrade

This repairs Windows but keeps are programs.

In 2015, Microsoft backported a DISM command from Windows 8 to Windows 7 to repair files. Look if it is possible to install the update KB2966583, open a command prompt as admin and run DISM /Online /Cleanup-Image /Scanhealth to try to repair files. But if this fails, try the inplace upgrade. Still is still the best option for Windows 7 to make sure it gets fully repaired.
