Difficulty: EasyResolving System File Corruption and Driver Issues

A technician needs to fix corrupted Windows system files on a user's computer after an interrupted system update. Arrange the steps in the correct sequential order to successfully perform the repair workflow, starting with the first action at the top.

  1. 1Open Command Prompt as an administrator.
  2. 2Execute dism /online /cleanup-image /restorehealth.
  3. 3Execute sfc /scannow.
  4. 4Restart the workstation and verify system functionality.

Answer

The correct sequence starts with opening an elevated Command Prompt, followed by running the DISM restorehealth command to fix the component store, running SFC scannow to repair corrupted system files, and finally restarting the computer.
The correct repair order requires opening Command Prompt as administrator, repairing the Windows component store using DISM, executing SFC to fix corrupted operating system files from the repaired component store, and restarting the computer to finalize the changes.

Step-by-Step Solution

1
Launch Command Prompt with elevated administrator credentials.
Elevated CLI session is established.
Low-level system maintenance utilities require administrative rights.
2
Run dism /online /cleanup-image /restorehealth.
The Windows side-by-side component store image is repaired.
SFC uses the component store to replace corrupt files; fixing DISM first prevents SFC from failing due to a damaged source.
3
Run sfc /scannow.
System binaries are integrity-checked and repaired.
SFC replaces damaged protected system files with clean copies from the restored store.
4
Reboot the operating system.
In-use system files are updated and verified.
A restart applies pending file operations and confirms stability.
