Windows 10: Update database corruption, my findings so far, Need advice on options

Problem

Windows upgrade from 1709 to 1803 fails


Symptom

Download success, preparations success, installation failure at ~60%


Error: SetupDiag reports down-level failure found.

Failure Data: Last Setup Phase = Downlevel

Last Setup Operation = Save boot entries for the old OS

Error = 0x80070005-0x5000F

LogEntry: 2019-01-01 22:13:16, Error SP CSetupPlatform::SuspendAndRelease: Error creating the Setup Platform key. Error: 0x80070005


Suggestion

It looks that my system split/migration from one SSD to a new SSD left an EFI partition on the source, now secondary disk (D). This disk contains all libraries like My Documents. Updates failed ever since I have added that drive. I have added an M.2 drive for all system files using a data migration tool by Samsung


I have already tried to

• Reset all registry, file and service permissions ( in safe mode) - what have I missed?
• Rename/remove/recreate Catroot & download folders
• browse though all the log files I could find in Panther folders
• Tried to repair with Media Creation Tool for 1803/1809 - same failure

Request for advice

Need advice if this indeed is the root-of-all-evil (as suggested here), and advice on follow up, i.e. how to check & "safely" remove this EFI partition from my secondary (D-)drive. My C-drive contains all windows system files. Can I perhaps test by unmounting D?


Both disks are 250GB SSD, Disk 0 is on a M.2


my partitions look like




help is appreciated

Windows Update Database Corruption

We appreciate the clarification that you have given about the steps given. Though the steps provided are more of a direct approach in resetting the Windows Update database. May we know if these steps have resolved the corruption in your Windows Update
Database?

 

Windows 10 wont update


Have you tried the second step?

(Searching for the error message e.g.

windows update database corrupt

is also a useful approach- e.g. finds
Win 10 Update Database Corruption Solved - Windows 10 Forums
- where the next step is the one I suggested above).

 

Pending Download - corrupted WU database


This have been working for a while, but now there's another pending update KB4346783 in stalled state. Running troubleshooter only discovers problems in windows update that is partially fixed but not the corrupt database.

I have followed all steps here and the database corruption is still not gone.

Now I can download the package manually from Windows Catalog, but the Windows Update service is unusable.
