Techopedia explains System File Checker (SFC)
With System File Checker, users can open a command prompt window and trigger a system scan that shows whether protected system files may be corrupted. Microsoft recommends not closing the command prompt window until completion of the scan.
System File Checker may return one of several messages – for example, System File Checker may say that the utility did not find integrity violations. System File Checker may say that the system could not perform the operation. The utility may also indicate that the system found corrupt files and repaired them. If System File Checker is not able to fix corrupted files, users can go in and replace them manually.
