In the first scenario, we will see the SFC and DISM commands to fix a corrupt windows system that can still boot properly. We will then cover the reasons for system file corruption and in which cases SFC and DISM can be helpful. Then we will see how to boot into the windows recovery console using the windows recovery partition. We will then see how to download and create a windows installation medium.

After that, we will see how to use this installation medium to boot your system into the recovery console.

Finally, we type the command for running DISM from the recovery console without an internet connection.
