Windows 10: Corrupt files not repaired by DISM

Hi,I have used DISM to check health of my system, Windows 10 Home Version 21H1 Installed on ‎02-‎Sep-‎20 OS build 19043.1288 It reports some files corrupt but can be repaired, scannow reports the same. But attempts to use DISM to repair files fails using either online repair or source files. I suspect that Group Policy Editor is denying access for these repairs to take place but GPE is not supported in Win 10. How can I correct this please ?

Corrupted file RAR

If the archive has been created using WinRAR, why don't you try WinRAR itself? It has a built-in repair feature for repairing corrupted archive (ZIP as well as RAR). Follow the steps given below:

• Open WinRAR application in your system.
• Now click on File tab > Open or simply press Ctrl+O.
• A small window "Find Archive" will pop up. Locate the corrupt RAR archive from your system directory and select it.
• Now click Open button.
• Click Tools tab > Repair archive or simply press Alt+R.
• Again a small window "Repairing File name.rar" will pop up.
• Now click Browse to select a location to save the repaired archive.
• Check the box "Treat the corrupt archive as RAR" and click OK.
• WinRAR will start repairing of corrupt RAR archive. Once it gets completed click Close.

I hope the above steps will help you repair the corrupted RAR archive.

Thanks.

Windows 10: sfc and dism cannot repair corruption

I was finally able to repair my Windows installation such that SFC returned a normal result.

Using a freshly downloaded USB image of W10, I did an inplace upgrade as suggested in magicandre1981's comments.

After that, there was a different file that was corrupt and could not be repaired.

Again, DISM did not initially repair this. However, I was able to determine that the file in question was located in the C:\windows\winsxs and also the C:\windows\system32 folders.

Since the previous installation did not flag that file as corrupt, I figured I could use the previous installations copy of that file as a good file.

Before running DISM again, I executed the following from an elevated command prompt and then re-booted the machine, as per instructions in an article at thewindowsclub.com which is not presently accessible. I'm not sure if the reboot is necessary, as that is not mentioned in another article.

By running DISM, and using c:\windows.old\windows\winsxs as the Source, I was able to repair the store. And then running SFC resulted in the original file being repaired.

Why this is happening, I have no idea. On a different machine, (and different internet connection/ISP) the upgraded (from W7) W10 installation also showed a corrupt file when running SFC. On that machine, DISM was able to repair it using the default Windows Update as a source.
