Zorluk: ZorResolving System File Corruption and Driver Issues

A help desk technician is servicing a Windows system that continuously displays blue screen errors following a failed feature update and an unverified graphics driver installation. Initial diagnostics indicate that both critical operating system binaries and the local component store have suffered data corruption. Which of the following troubleshooting steps should the technician take to repair the component store, replace damaged system files, and restore driver stability? (Select TWO.)

  1. Execute dism /online /cleanup-image /restorehealth from an elevated command prompt prior to running system file scans.Cevap
  2. Boot the system into Safe Mode and use Device Manager to roll back the display driver to its previously installed version.Cevap
  3. C
    Run sfc /scannow to fix damaged operating system files before repairing the WinSxS component store.
  4. D
    Run chkdsk /r /f to download replacement system DLLs and driver binaries directly from Microsoft servers.

Cevap

The technician must first execute DISM with the RestoreHealth switch to repair the local component store, and use Safe Mode along with Device Manager to roll back the unstable graphics driver.
Executing DISM with the RestoreHealth switch repairs the Windows Component Store image using online or local repair sources, ensuring System File Checker has valid file payloads available. Additionally, booting into Safe Mode allows the technician to bypass active driver crashes and use Device Manager to roll back to a known-working device driver.

Adım Adım Çözüm

1
Repair the local Component Store using DISM
Executes 'dism /online /cleanup-image /restorehealth' to fix payload files in WinSxS using Windows Update as a reference source.
SFC relies on the WinSxS store to copy healthy replacements of corrupted system files. If the store itself is corrupt, DISM must fix it first.
2
Run System File Checker (SFC)
Executes 'sfc /scannow' to verify system integrity and repair damaged OS files using the newly validated component store.
With a healthy component store, SFC can successfully repair missing or corrupted system files.
3
Resolve driver instability via Safe Mode
Boots into Windows Safe Mode and uses Device Manager to perform a driver rollback on the graphics adapter.
Safe Mode prevents problematic third-party drivers from loading, allowing the technician to restore the previously working driver version safely.
