Windows Vista System File Integrity Check Method

Malware or viruses often achieve the goal of invading the system by modifying system files. Therefore, ensuring the integrity of system files becomes the first line of defense to maintain system security and normal operation.

/OffWinDir : Specify the Windows directory location when offline repair;
