Zorluk: OrtaTroubleshooting Windows Performance and Application Crashes

A user reports that a 3D modeling application crashes unexpectedly whenever high-resolution assets are exported on a Windows 11 workstation. A technician inspects Event Viewer and identifies an Application Error (Event ID 1000) indicating that a core system library, ntdll.dll, is the faulting module. Which of the following commands should the technician execute FIRST in an elevated command prompt to resolve this issue?

  1. sfc /scannowCevap
  2. B
    chkdsk /f
  3. C
    services.msc
  4. D
    format C:

Cevap

Run sfc /scannow from an elevated command prompt to verify and replace corrupted operating system files.
Running the command 'sfc /scannow' executes the System File Checker utility, which inspects all protected Windows system files and replaces corrupted dynamic link libraries (such as ntdll.dll) with clean cached copies from the Windows component store.

Adım Adım Çözüm

1
Analyze the Event Viewer log details.
Identified Event ID 1000 with ntdll.dll listed as the faulting module, indicating a potential Windows core system file corruption.
Event ID 1000 application crashes referencing system DLLs point to corrupted or missing Windows operating system binaries.
2
Select the appropriate administrative tool to scan and repair protected operating system files.
Determined that System File Checker (sfc /scannow) is designed to inspect and repair system file corruption.
SFC checks the integrity of all protected system files and replaces corrupted versions with valid copies from the cached Windows store.
3
Execute sfc /scannow in an elevated command prompt.
The utility repairs ntdll.dll without requiring an OS reinstallation or destructive disk operations.
Using non-destructive isolation tools first follows proper CompTIA A+ troubleshooting methodology.
