A technician is servicing a Windows workstation that exhibits system instability and missing file errors. Diagnostic logs indicate that both protected operating system files and the local Windows component store (WinSxS) are corrupted. How should the technician sequence the remediation steps to resolve the corruption completely?
- 1Open a Command Prompt window using administrative credentials.
- 2Run dism /online /cleanup-image /scanhealth to assess component store corruption.
- 3Run dism /online /cleanup-image /restorehealth to repair the component store.
- 4Run sfc /scannow to inspect and replace damaged protected system files.
- 5Restart the workstation to finalize the replacement of locked system files.
Answer
The correct repair sequence is: 1) Open an elevated Command Prompt, 2) Run DISM /scanhealth to verify component store corruption, 3) Run DISM /restorehealth to repair the component store image, 4) Execute SFC /scannow to repair protected operating system files, and 5) Restart the workstation.
Resolving system file corruption when the underlying component store (WinSxS) is damaged requires repairing the payload source prior to repairing the OS files. The process begins by opening an elevated Command Prompt. Next, DISM /scanhealth verifies component store damage, followed by DISM /restorehealth to rebuild the store. Once the store is healthy, SFC /scannow repairs damaged system files. Finally, restarting the system completes the replacement of files locked during operation.
