Symptom & Impact

DISM /RestoreHealth completes with errors on Windows Server 2012 R2 and reports component store corruption that prevents future updates.

Environment & Reproduction

Occurs after partial cumulative update installs or abrupt shutdowns during servicing operations.

dism /online /cleanup-image /scanhealth
dism /online /cleanup-image /restorehealth

Root Cause Analysis

CBS database entries reference missing payloads, often because Windows Update Cleanup removed superseded components still needed for repair.

Quick Triage

Identify the failing package by checking the DISM log for the first 0x800f081f entry.

Select-String -Path C:WindowsLogsDISMdism.log -Pattern '0x800f081f'

Step-by-Step Diagnosis

Determine the package KB and locate matching source media or WIM.

Get-WindowsPackage -Online | Sort InstallTime -Desc | Select PackageName -First 20

Solution — Primary Fix

Run DISM with an explicit source pointing to a clean install.wim matching the same patch level.

dism /online /cleanup-image /restorehealth /source:WIM:E:sourcesinstall.wim:1 /limitaccess
sfc /scannow

Solution — Alternative Approaches

Mount an offline image, apply latest LCU, and use it as the repair source for the running OS.

dism /mount-image /imagefile:E:sourcesinstall.wim /index:1 /mountdir:C:wim
dism /image:C:wim /add-package /packagepath:C:updates

Verification & Acceptance Criteria

DISM reports component store healthy and subsequent updates install without failure.

dism /online /cleanup-image /checkhealth
sfc /verifyonly

Rollback Plan

Restore from a recent system state backup when corruption is too deep to repair in place.

wbadmin start systemstaterecovery -version:

Prevention & Hardening

Avoid component cleanup before all pending updates apply and maintain matching install media on file shares.
