Cevabı ve açıklamayı göster

Cevap

The correct troubleshooting sequence requires accessing WinRE Command Prompt, executing DISM with /revertpendingactions to clear pending driver installations, running DISM /restorehealth with an external source to repair the offline component store, running SFC with /offbootdir and /offwindir to repair corrupted protected files, and finally restarting the workstation.
The proper sequence begins by entering WinRE Command Prompt to perform offline servicing. Next, pending driver updates and operations must be reverted using `/revertpendingactions` to unlock system file operations. DISM `/restorehealth` must then be executed using an external WIM source to restore the integrity of the offline component store (WinSxS). Once the component store is healthy, SFC (`sfc /scannow`) with `/offbootdir` and `/offwindir` can effectively repair corrupted system files. Finally, restarting the system verifies operating system functionality.

Adım Adım Çözüm

1
Boot into Windows Recovery Environment (WinRE) Command Prompt.
Establishes an offline repair environment where locked OS files can be serviced.
System repair tools cannot modify active OS driver dependencies while Windows is running or failing to boot normally.
2
Run `dism /image:C:\ /cleanup-image /revertpendingactions`.
Cancels stuck driver updates and pending servicing tasks.
Pending update locks prevent DISM and SFC from successfully modifying system files.
3
Run `dism /image:C:\ /cleanup-image /restorehealth /source:wim:D:\sources\install.wim:1`.
Repairs corrupted component store files in C:\Windows\WinSxS using clean source payloads from the installation media.
SFC relies on the component store payload repository; repairing the component store first ensures SFC has valid replacement files.
4
Run `sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows`.
Scans protected offline system files and replaces corrupted binaries using the healthy component store.
SFC requires explicit offline boot and Windows directory parameters when executed from WinRE.
5
Reboot the system.
Verifies system recovery and allows normal driver initialization.
Final validation confirms the operating system boots cleanly after corruption resolution.
