sfc finds corrupt files but cannot repair

[Errol]

When I run my system backup program, it fails with a message about corrupted files. So I ran sfc /scannow, and it found some corrupted files which it said it could not repair.

So I ran the disk checker, which found no errors on the HD.

So what other program can I run to check and correct the system files? If any.

Win 7 boots fine, and seems to run without problems, but I now cannot run a system backup. I have been using Image for Windows for many years with no problems. It backs up my Win 10 partition (on a separate HD - I have a multiboot setup) without problems.

When SFC/scannow reports unfixable files, you can manually replace the corrupted files if you know their names and paths. Here's how:

1. Open the CBS.log file at C:\Windows\Logs\CBS\CBS.log to find details about the problematic files.
2. Search for entries containing "Cannot repair member file" or "Cannot verify component files".
3. Note the exact file paths and names.
4. Obtain a clean copy of the file:
   • Use another Windows 7 system with the same version and architecture.
   • Extract the file from the Windows 7 installation media:
     • Mount the ISO or insert the DVD.
     • Use a tool like 7-Zip to extract the required file from the install.wim or install. esd file located in the sources directory.
5. Replace the corrupted file manually:
   • Take ownership of the original file (takedown and icacls command in Command Prompt).
   • Rename the corrupted file as a backup.
   • Copy the new file to the correct location.

Try running DISM to fix system files that sfc couldn't repair. Open Command Prompt as an administrator and run:

```bash
DISM /Online /Cleanup-Image /RestoreHealth
```

This should help repair any corrupted files. If that doesn't work, you can also try CHKDSK with the repair option, although since your disk didn't show errors, it might not be necessary.

Be careful when using an FTP program with MS Frontpage. If you use Microsoft Frontpage to upload your website then later use some type of FTP program, then it will sometimes corrupt the Frontpage extensions on your server and they will have to be reinstalled.
