 Imagine booting up your computer, only to be greeted by ominous error messages or sluggish performance. In such dire moments, users often turn to diagnostic tools like chkdsk, scandisk, sfc, and dism to unravel the mysteries plaguing their systems.

Why Users Need to Run chkdsk/scandisk/sfc/dism:

The need to run chkdsk, scandisk, sfc, or dism arises from various system maladies. File system corruption, disk errors, missing system files, and component corruption can manifest as system instability, application crashes, or data loss. Running these tools can help identify and rectify these underlying issues, restoring system integrity and functionality.

Differences among chkdsk/scandisk/sfc/dism:

While chkdsk, scandisk, sfc, and dism share the common goal of system repair and maintenance, they operate at different levels and cater to distinct issues.

Tool Purpose Scope
chkdsk Checks and repairs file system Disk level
scandisk Disk error detection and repair Disk level
sfc System File Checker System file level
dism Deployment Image Servicing Image management

Feasible Fixes for Corrupted Files:

1. System File Checker (sfc):

Background: System File Checker (sfc) is a built-in Windows utility that scans and repairs corrupted system files. These files are vital for the stability and functionality of the Windows operating system.


Open Command Prompt as Administrator.

Enter "sfc /scannow" and press Enter.

Wait for the scan to complete. If sfc finds any corrupted files, it will attempt to repair them automatically.

2. Deployment Image Servicing (dism):

Background: Deployment Image Servicing and Management (dism) is a command-line tool used to service and prepare Windows images, including those used for Windows Recovery Environment, Windows Setup, and Windows PE.


Open Command Prompt as Administrator.

Enter "dism /online /cleanup-image /restorehealth" and press Enter.

DISM will scan and repair the Windows image. This process may take some time, and it's important not to interrupt it.
