Explanation

SFC (System File Checker) is a built-in Windows command-line utility (run as 'sfc /scannow') that scans the integrity of all protected operating system files and replaces incorrect, corrupted, missing, or changed versions with the correct Microsoft versions. RECOVER is used to recover readable data from a bad disk sector. REPLACE is an older command to replace files in one directory with files from another. COPY simply duplicates files and has no system-file verification capability.
