The full name of DISM is Deployment Image Service and Management. It is a command line tool for serving, preparing, modifying, and repairing system images used by Windows Setup, Windows PE, and Windows RE (Windows Recovery Environment).
DISM.exe (also known as the DISM Image Service Utility file) runtime always targets the region of your choice. Before introducing how to use Windows DISM tools, it is necessary to introduce the commonly used DISM command switches.

However, if you specify the /Online switch (DISM.exe /Online), the command will instead target your online operating system file instead of the offline image.

By providing the Cleanup-Image switch (DISM.exe /Online /Cleanup-Image), you can ask the DISM tool to perform two actions:
- For running operating systems.
- Clean and restore operations and tasks on the system.
Restorehealth switch
The Restorehealth switch in the DISM command indicates that the tool scans for damaged files in the running operating system and tries to automatically repair them.
DISM.exe /Online /Cleanup-Image /ScanHealth
