Microsoft, in turn, wrote the following, "I would like to inform that if you are not able to repair

This is the 'Error: #87' as it was listed in the scrolled error in the cp. In neither did I findĪ "scanhealth" option in the "Online" executed folder. The result was that the 'DISM.exe/online/cleanup-image/scannow' was unable to execute due to an #87 error - "the cleanup-image/scanhealth option is unknown." So, I executed the DSM.exe/? and DISM.exe/Online/?. The list prompt mentioned that the corrupted files were 'unable to fix them'. I have been having the same issue and results are noted below if it helps you: (As per Microsoft) the SFC was able to cleanup some files, but not all.
#WINDOWS UPDATE TO REPAIR CORRUPTED FILES WINDOWS 10#
Suggestions repair corrupt system files Windows 10 How can I get replacements for the 4 damaged dlls. I though that's what dism did, but apparently not. I think I need to replace the contents of the affected 4 dlls.

Each ran to between 20% and 25%, reported a 605 error and stopped. I ran DISM with /scanhealth, /checkhealth, and /repairhelalth. I ran sfc /scannow which ran to 25% and said "Windows Resource Protection could not perform the requested operation" I ran chkdsk, which detected no errors and got the same result afterwards. Since system dlls are compressed, I suspect this means that decompression is failing because the file content is corrupted. The text for this error talk about a badly formatted compression buffer. With this, I discovered that on each file near the end of the file, ReadFile returned windows error 605. After a couple of rounds with their tech support, I gave up and wrote a small Win32 program that read the file and reported errors. I recently notice that my backup program was failing to back up 4 files, all lsyste dlls, giving the error "Unknown windows error". I am currently running Windows build 17134.228. This will be a bit long because I intend to cover everything.
