Solutions

Solution 1: Clean Up Component Store

1Open Command Prompt as Administrator
2Analyze component store: DISM /Online /Cleanup-Image /AnalyzeComponentStore
3If cleanup is recommended: DISM /Online /Cleanup-Image /StartComponentCleanup
4For aggressive cleanup of all superseded versions:
5DISM /Online /Cleanup-Image /StartComponentCleanup /ResetBase
6Warning: /ResetBase removes ability to uninstall updates — use carefully
7Check remaining WinSxS size — most is hard-linked (actual size is smaller)
8To see true size: DISM /Online /Cleanup-Image /AnalyzeComponentStore

Solution 2: Repair Corrupted Component Store

1Open Command Prompt as Administrator
2Check for corruption: DISM /Online /Cleanup-Image /CheckHealth
3If corruption detected: DISM /Online /Cleanup-Image /RestoreHealth
4If RestoreHealth fails (no source), use a Windows ISO:
5Mount the ISO or insert Windows installation media
6DISM /Online /Cleanup-Image /RestoreHealth /Source:D:\sources\install.wim
7Replace D: with your media drive letter
8After DISM completes, run: sfc /scannow

Solution 3: Fix Pending Operations and CBS Errors

1If component servicing is stuck:
2Open Command Prompt as Administrator
3Check for pending operations:
4DISM /Online /Cleanup-Image /RevertPendingActions
5This cancels incomplete servicing operations
6Restart the computer
7Check CBS log: type %windir%\Logs\CBS\CBS.log | findstr /i "error"
8If errors persist, rename the pending.xml:
9ren %windir%\WinSxS\pending.xml pending.xml.bak
10Restart and retry Windows Update
