If you execute this command, DISM /Onlinethis signifies that you are modifying an online image (does not signify that a scan will run over the internet).
If you execute this command: DISM /Online /Cleanup-Image then this triggers a more extensive check which can resolve issues with the store.
If you execute this command: DISM /Online /Cleanup-Image /CheckHealth, it starts a basic check to see if corruption has been detected in the store.
If you execute this command: DISM /Online /Cleanup-Image /ScanHealth, performs a more comprehensive scan of the store for corruption.
At this point, no corruption is fixed but creates logs of corruption. You can find it here: C:\Windows\Logs\CBS\CBS.log

Launch Command Prompt with admin rights and execute the following command: dism /get-wiminfo /wimfile:F:\sources\install.wim
In case, your ISO image includes the ‘install.esd’ file, then replace ‘install.win’ with ‘install.esd’ in the above command.
Now you will get details for an image in that source. You need to make note of the index that matches your current edition of Windows11. My device runs Windows 11 Pro edition, then Index 6 is for my machine.
