DISM.exe /Online /Cleanup-Image /Restorehealth” is a Dism command that runs a scan for corruption and repairs problems that it finds with the operating system you are logged into.
DISM
The deployment image servicing and management tool (DISM) is manipulated to scan and restore potential issues within the windows that may impact an operating system.
Dism.exe switches
Dism.exe will always target your chosen area; you must either specify the /online or /Image switch. Dism.exe will not foresee a path to an offline image.
- Image switch and online switch
On the other hand, if you consider /image switch, DISM will expect you to restrict the path to the root directory of an offline Windows image. However, the DISM.exe /Online switch means you ask DISM to target the operating system instead of an offline image.
What is a /Cleanup-image switch? How does it work? In this section, we will explain it to you:
For this deployment Image Servicing and Management tool to work, you need to follow other image servicing tools and commands with /online or /Image switch. One of the few is the cleanup-image switch.
- Cleanup-image switch
This switch functions to clean and recover operations and undertakings on the running operating network in Dism.exe/online/Cleanup-image/ Restorehealth” command. Which means when you run dism.exe/Online/Cleanup-image, you are asking the Dism tool to:
- Cleanup and repair operations on the system.
- Target running operating system.
The next and last switch is the “DISM.exe /Online /Cleanup-Image /Restorehealth” command is the /Restorehealth switch.”
/Restorehealth switch
It attempts to repair the corrupted scanned files automatically from the operating network.
DISM.exe /Online /Cleanup-Image /Restorehealth” command does the following:
1) The online switch requires DISM.exe to target the running operating system rather than offline windows image(.wim) or virtual hard disk.
2) The cleanup-image switch has to go for cleaning and recovery operation on a system.
3) The last one, /Restorehealth Switch, scans the ongoing operating system for corrupt files and attempts to restore them.
