The results of my recent SFC scan have returned bad:

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.

This Microsoft Support article says the backup files are stored in %WinDir%\System32\dllcache. So I embarked on the adventure into hidden system files. Result? dllcache does not exist!

Digging deeper, I found this, which says dllcache was replaced with C:\Windows\winsxs\Backup starting with Windows Vista. Navigating there, all I find is a jumble of files where none of them have the name of the file which I'm trying to replace.

What I did find was that there was a MANIFEST file with the exact same name as the parent folder of the corrupt file.

Any words on this?

sfcdetails: All files have "Verify complete" except for the following (which is repeated in the log 3 times with different times and CSI numbers):

    Feel free to provide the relevant information from the log file that was generated. – Ramhound Jul 13 '15 at 16:31
  • Updated with log information from CBS.log. – boxspah Jul 13 '15 at 16:36
  • I could find no mention whatever of "dllcache" in the MS article you link to; it only suggests obtaining a copy of the corrupt file from another Windows installation. I hardly think there would be a spare copy on your computer without the System File Checker knowing about it or being able to use it. – kreemoweet Jul 13 '15 at 17:40
  • Step 2. "The sfc /scannow command will scan all protected system files, and replace corrupted files with a cached copy that is located in a compressed folder at %WinDir%\System32\dllcache. " – boxspah Jul 13 '15 at 17:44

    next step to repair prncacla.inf – Ramhound Jul 13 '15 at 18:21

Thanks to Ramhound for the reference:

Windows cant repair even with sfc /scannow

After running dism /online /cleanup-image /restorehealth and restarting my computer, System Restore works again!
