Hi Ghritak
Please explain more on this, what is the initial problem you are having on your PC that is causing you to scan your PC
Those commands have different purposes . ..
sfc /scannow will scan your Windows System files for errors and if those are found, you should run this command:
dism /online /cleanup-image /restorehealth
chkdsk will only scan your hard drive for errors
So the choice of command you choose to run should be dependent on the type of problem you are encountering
