How to Fix It
1
Run the Windows Update Troubleshooter: Settings > System > Troubleshoot > Other troubleshooters > Windows Update.
2
Run DISM to repair the component store: Open Command Prompt as Administrator and run: DISM /Online /Cleanup-Image /RestoreHealth.
3
Run System File Checker: sfc /scannow — if it reports files that could not be repaired, run the DISM command first, then sfc /scannow again.
4
Reset the Windows Update components manually: Stop services (net stop wuauserv, net stop cryptsvc, net stop bits, net stop msiserver), rename C:\Windows\SoftwareDistribution to .old, rename C:\Windows\System32\catroot2 to .old, then restart all four services.
5
Check the CBS log at C:\Windows\Logs\CBS\CBS.log for specific component names that are missing. Search for 'Element not found' entries to identify the exact failing component.
6
If a specific update KB fails, download it manually from the Microsoft Update Catalog and install using the standalone installer (wusa.exe).
7
As a last resort, run an in-place repair upgrade using the Windows Media Creation Tool to restore all system components without losing data.
