DISM (Deployment Imaging Service and Management Tool) is a system image management tool built into Windows. It requires no installation and is run through the command line (cmd or PowerShell). DISM is used to resolve issues caused by corrupted system files, such as Windows update failures, app launch errors, or malfunctioning features.
Here are some commonly used commands:
DISM /Online /Cleanup-Image /CheckHealth
Quickly checks for any corruption in the system image.
DISM /Online /Cleanup-Image /ScanHealth
Performs a thorough scan of the system image.
DISM /Online /Cleanup-Image /RestoreHealth
Repairs any detected corruption in the system files.
DISM can also be used to mount and inspect .wim images or .vhd virtual disks. In addition to system repair, it is also used for managing images in large-scale deployments.
