Chkdsk , Sfc, Dism Explained | What are the Differences Between CHKDSK, SFC, and DISM in Windows 10

In this video I am explaining the difference between CHKDSK, SFC, and DISM in Windows 10.

Windows 10’s built-in diagnostic tools such as CHKDSK, SFC, and DISM are used to check the health of your hard drive and repair corrupt files, but the three tools work in different ways and target different areas of your system.

CHKDSK scans your entire hard drive to find and fix errors in files and the file system itself. It also checks your drive for bad sectors (clusters of data that cannot be read) and either tries to repair them or tells your system not to use them.

To make CHKDSK fix the problems it finds, type chkdsk /f c: (for your C: drive).

To scan for bad sectors as well as errors, type chkdsk /r c:.

SFC (System File Checker) specifically scans and repairs Windows system files. If it detects that a file has been corrupted or modified, SFC automatically replaces that file with the correct version.

Command 1: sfc /scannow
Command 2: sfc /verifyonly

What is DISM?

DISM (Deployment Image Servicing and Management) is the most powerful of the three Windows diagnostic tools. It can be used when experiencing frequent crashes, freezes, and errors, but SFC either can’t repair your system files or is unable to run at all.

Dism /Online /Cleanup-Image /CheckHealth

Dism /Online /Cleanup-Image /ScanHealth

Dism /Online /Cleanup-Image /RestoreHealth

I use this in PowerShell sfc /scannow, I mainly find it also works much better. say for example if U use AVG antivirus free it repairs fair few problems & dism is good to.. I mainly never scan my PC with antivirus avg software protection anymore, because it's easy to just use the PowerShell or cmd commands ether one works for best results, I've used Regedit Tricks many times before✌🏿.
