Use the system file checker

If your Windows is not quite normal recently, have you thought of using the System File Checker? The System File Checker detects the integrity of operating system files and can restore them if they are corrupted. You can also extract compressed files (such as drivers) from the installation disk. Also, the System File Checker can back up existing files before restoring the original files. You can also customize your search criteria based on folder and file extensions. Here, the author makes a brief description of the use of the "system file checker".
