Explanation
SFC (System File Checker) is a built-in Windows utility (run as 'sfc /scannow') that scans protected operating system files and replaces corrupted or missing ones with cached originals. Viruses commonly corrupt or delete system files, making SFC the ideal recovery tool. CHKDSK checks the disk's file system and sectors for errors but does not repair OS system files. TASKKILL terminates running processes, and DISKPART manages disk partitions - neither addresses corrupted system files.
