About System File Checker (sfc.exe) & sfc/scannow

In Windows operating system, System File Check (sfc.exe) is integrated with Windows Resource Protection, which protects registry keys and folders as well as critical system files. Sfc utility can be invoked via Windows Command Prompt. And, the command sfc/scannow is used to scan all protected system files, if it finds a problem, it will attempt to replace the problematic files with a cached copy that is located in a compressed folder at %WinDir%\System32\dllcache. 


Ideally, running sfc/scannow command would automatically fix corrupted system files for us, not in the situation when the file is not in the dll cache or it got corrupted. At this moment, sfc/scannow will send error 'Windows Resource Protection found corrupt files but was unable to fix some of them'.

Don't be afraid. When you're caught in troubles as we mentioned, go to fix it by yourself. Here are some general troubleshooting methods that will help resolve the case promptly.
