Difficulty: MediumTroubleshooting Windows Performance and Application Crashes

A technician is troubleshooting a Windows 11 workstation where a graphic design application repeatedly crashes whenever a rendering task is initiated. In Event Viewer, the Application log records an Event ID 1000 entry identifying the faulting module as d3d11.dll. Which of the following command-line tools should the technician run FIRST to scan and repair this protected operating system file?

  1. sfc /scannowAnswer
  2. B
    chkdsk C: /r
  3. C
    dism /online /cleanup-image /analyzecomponentstore
  4. D
    perfmon /sys

Answer

The technician should execute sfc /scannow from an elevated command prompt.
Executing System File Checker (sfc /scannow) scans all protected Windows system files and replaces corrupted binaries, such as d3d11.dll, with clean copies from the local cached repository.

Step-by-Step Solution

1
Analyze the crash details provided in Event Viewer.
Event ID 1000 indicates an application crash caused by a specific faulting module, d3d11.dll, which is a core Windows system library file.
Identifying whether the faulting module is a core operating system component or a third-party file determines the correct repair vector.
2
Select the appropriate utility to verify system file integrity.
System File Checker (SFC) scans protected system binaries and replaces corrupted files using the local component store cache.
Executing sfc /scannow is the recommended first repair step when a core Windows system file is flagged as corrupted or faulting.
