A user is experiencing issues with their Windows 11 system where certain system files appear to be corrupted, causing applications to crash. They have already run 'sfc /scannow' but it reported that it could not fix all corrupted files. Which command-line tool should the technician use next to attempt to repair the Windows image?
- ADISM /Online /Cleanup-Image /RestoreHealth
- Bbootrec /fixboot
- Cchkdsk /f
- Dpowercfg /hibernate off
Show answer & explanationAnswer & explanation
Correct answer: A. DISM /Online /Cleanup-Image /RestoreHealth
The DISM (Deployment Image Servicing and Management) tool, specifically the /RestoreHealth option, is used to repair corrupted Windows images. It downloads necessary files from Windows Update to fix issues that SFC alone cannot resolve.
Why the other options are wrong
- B. bootrec /fixboot is used to repair the boot sector, not corrupted system files within the OS image.
- C. chkdsk /f checks and fixes file system errors on a disk, not Windows image corruption.
- D. powercfg /hibernate off disables hibernation, unrelated to system file corruption.
DISM RestoreHealth
A command-line option for the Deployment Image Servicing and Management (DISM) tool used to repair a corrupted Windows image by replacing damaged files from Windows Update.
- Used when SFC /scannow fails to fix issues.
- Requires an internet connection to download healthy files.
- Repairs the Windows Component Store.
