A system administrator is troubleshooting an offline Windows 11 workstation after an abrupt power loss corrupted core system binaries. Running the System File Checker utility (`sfc /scannow`) reports that corrupt files were found, but Windows Resource Protection could not repair them because the local side-by-side component store is also corrupted. The administrator mounts a clean Windows 11 installation ISO onto drive E:. Which command should the administrator run first to repair the component store using the mounted media?
- dism /online /cleanup-image /restorehealth /source:E:\sources\install.wim /limitaccessAnswer
- Bsfc /scannow /source:E:\sources\install.wim /limitaccess
- Csfc /scannow /purgecache
- DOpen Event Viewer, clear the System log, and launch the Device Manager repair wizard
Answer
Run dism /online /cleanup-image /restorehealth /source:E:\sources\install.wim /limitaccess to repair the local component store before running SFC.
The correct command uses Deployment Image Servicing and Management (DISM) with the `/online` parameter to target the running operating system, `/cleanup-image /restorehealth` to fix image corruption, `/source` pointing to the install.wim file on the mounted media, and `/limitaccess` to prevent the tool from reaching out to Windows Update since the machine is offline.
