SFC Scannow command is a built-in utility that lets you scan for corrupted files on your Windows system and automatically repair them. This command scans all the Windows system files, including DLL files, which are the most integral files of Windows. It works on replacing incorrect, corrupted, changed, or damaged system files with the cached version of the files. The SFC Scan command automatically modifies the Windows system files and settings, including DLL files, to resolve the issue.
If it finds issues with the system settings, it restores the particular setting by returning it to the default. The System File Checker Scannow command is one of the best commands to troubleshoot all Windows-related errors with ease.
