I reset all Win 10 Home local policy permissions to their defaults using "secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose", which solved nothing.

I used the Winaero Tweaks tool for mass-resetting permissions on all top directories, subdirectories and files on my C: drive. Also for the drives with the auto-add directories. Nothing changed.

I manually changed permissions of certain directories to ensure they were loose enough.

Win 10 Event Viewer continues to show the same UAC error for the Calibre auto-add worker process as described and discussed in previous posts.

The only way to get auto-add to add is to run Calibre from source that I changed (as shown in a prior post), and to run Calibre via a Task at the "highest level of security" (as described in a prior post). It still cannot delete the original books just auto-added. UAC is stopping it.

UAC is the problem. No other software. The debug logs and the Event Viewer all show the same UAC error and reason.


The only option remaining (other than turning off auto-add so it does not run and fail every few seconds endlessly in the background as shown by the debug log and the Event Viewer) is to install Windows 10 Pro and mess with the security policy editors that come with Pro (not Home).
