SFC, CHKDSK, and DISM are all tools available in Windows 10 for diagnosing and repairing various issues related to the operating system. Here are the differences between them:
System File Checker (SFC):
The System File Checker (SFC) is a built-in Windows tool that checks for any corrupted or missing system files and repairs them. SFC scans all protected system files and replaces incorrect versions with the correct Microsoft versions.
Check Disk (CHKDSK):
The Check Disk (CHKDSK) is a command-line utility tool that checks the file system and the hard drive for errors, bad sectors, and physical damage. CHKDSK can also repair certain types of file system errors.
Deployment Image Servicing and Management (DISM):
The Deployment Image Servicing and Management (DISM) tool is used to repair Windows images, including the operating system, Windows components, and drivers. DISM can repair system files, check the system image for corruption, and restore the system to a known good state.
In summary, SFC checks for and replaces corrupted system files, CHKDSK checks the hard drive for errors and repairs file system issues, while DISM repairs the Windows image, including the operating system and its components
