Sto usando Windows 8.1 x64, build 6.3.9600.16384, usando il Prompt dei comandi con privilegi di amministratore.

sfc /scannow

ritorna:

...found corrupt files but was unable to fix some of them.

e

dism /online /cleanup-image /restorehealth

ritorna:

Error: 0x800f0906
The source files could not be downloaded.

(e il servizio Windows Update non è in grado di avviarsi perché mancano quei file.)

anche provato

dism /online /cleanup-image /restorehealth /source:wim:F:\sources\install.wim:1 /limitaccess

e restituito:

Version: 6.3.9600.16384
Image Version: 6.3.9600.16384
Error: 0x800f081f
The source files could not be found.

Ho montato l'immagine e ho provato da lì.

dism /mount-image /imagefile:F:\sources\install.wim /index:1 /mountdir:C:\offline

dism /online /cleanup-image /restoreHealth /source:c:\offline /limitaccess

anche di ritorno:

Error: 0x800f081f

Come riparo i file di sistema corrotti?

Posso dire a DISM di usare il disco di installazione di Windows come sorgente?

Filtraggio dei dettagli

L'esecuzione del file sfc /scannowprodurrà un CBS.logfile di report (di solito si trova in C:\Windows\Logs\CBS) che contiene molte informazioni. Per ottenere i bit succosi, apri un prompt dei comandi ed esegui questo comando:

findstr /i /c:"[SR]" "%windir%\Logs\CBS\CBS.log" | findstr /i /v /c:"verify" > "%userprofile%\Desktop\sfc.txt"

Il comando sopra sarà:

1. Ottieni tutte le righe nel file originale contenente [SR], che sono quelle che tengono traccia dei tentativi di riparazione.

2. Rimuovere tutte le righe contenenti verifyda ciò che abbiamo ottenuto nel passaggio precedente per ridurre ulteriormente il disordine.

3. Scrivi i risultati nel sfc.txtfile per successive analisi.

In questo caso, questo sarebbe il file risultante:

Ogni voce segue questo schema approssimativo:

• Cannot repair member file [...]"Generic.xbf"
  Il file che deve essere riparato.

• of Microsoft-Windows-Camera-LockScreenCamera-Main,
  Il nome del pacchetto a cui appartiene il file.

• Version = 6.3.9600.16485,
  Versione del file (maggiore, minore, build e revisione).

• pA = PROCESSOR_ARCHITECTURE_AMD64 (9),
  L' architettura del processore mirata .

• Culture neutral, [...],
  Neutro o il nome della cultura correlata se localizzato.

• file is missing
  Motivo per cui il file deve essere riparato.

Ci sono tre Generic.xbffile mancanti. Inoltre, tutti condividono questo bit di informazioni:

Ciò significa che il file è incluso nell'aggiornamento di Windows KB2914218.

Riparazione manuale

1. Ottieni il pacchetto di aggiornamento KB2914218 .

2. Estrarre il .msufile scaricato utilizzando 7-Zip in una cartella che prende il nome dal file originale (ad es Windows8.1-KB2914218-x64.).

3. Aprire un prompt dei comandi come amministratore e accedere alla cartella effettiva utilizzando il comando seguente:

   cd /d "X:\Whatever\Windows8.1-KB2914218-x64"
   

4. Espandi l'archivio cabinet contenente i file di aggiornamento nella directory corrente:

   expand Windows8.1-KB2914218-x64.cab -f:* %cd%
   

5. Ogni pacchetto ha un .manifestfile associato che elenca i file raggruppati. Per determinare dove è archiviato ciascun file, eseguire il comando seguente sostituendo packagaNamee fileName.extcon i valori effettivi:

   for /f "delims=" %A in ('"findstr /i /m /c:"packageName" *.manifest"') do @for /f "delims=" %B in ('"findstr /i /m /c:"fileName.ext" %A"') do @echo %~nB;fileName.ext>>fixes.txt
   

   Per esempio:

   for /f "delims=" %A in ('"findstr /i /m /c:"Microsoft-Windows-Camera-LockScreenCamera-Main" *.manifest"') do @for /f "delims=" %B in ('"findstr /i /m /c:"Generic.xbf" %A"') do @echo %~nB;Generic.xbf>>fixes.txt
   

6. Ripetere il passaggio 5 per qualsiasi altro file che deve essere corretto.

7. Assumi la proprietà e il pieno controllo della C:\Windows\winsxscartella:

   takeown /f "%windir%\winsxs" /a
   icacls "%windir%\winsxs" /grant:r *S-1-5-32-544:(OI)(CI)(F) /q
   

8. Crea qualsiasi cartella mancante:

   for /f "tokens=1 delims=;" %G in (fixes.txt) do @if not exist "%windir%\winsxs\%~G\" @md "%windir%\winsxs\%~G"
   

9. Assumi il pieno controllo delle cartelle richieste:

   for /f "tokens=1 delims=;" %G in (fixes.txt) do takeown /f "%windir%\winsxs\%~G" /a >nul & icacls "%windir%\winsxs\%~G" /grant:r *S-1-5-32-544:(OI)(CI)(F) /q
   

10. Ripristina i file:

    for /f "tokens=1,2 delims=;" %A in (fixes.txt) do copy /y ".\%A\%B" "%windir%\winsxs\%A\%B"
    

11. Ripeti il ​​controllo dei file di sistema per assicurarti che i problemi siano stati risolti:

    sfc /scannow
    

Riferimenti

• Utilizzare lo strumento Controllo file di sistema per riparare file di sistema mancanti o danneggiati
• Come eseguire il comando "SFC / SCANNOW" all'avvio o in Windows 8 e 8.1

Se non è possibile avviare Windows, è possibile eseguire SFC dalla console di ripristino di Windows:

sfc /scannow /offbootdir=d:\ /offwindir=d:\windows
