Error 0x80073701 - when trying to install 2020-05 Cumulative Update for Windows 10 Version 1909 for x64-based Systems (KB4556799)

[packko]

HI there,

This whole thing started with the prompt "Your device is missing important security and quality fixes." on Windows 1903.

performed a Windows update Troubleshooter - it showed it fixed issues (pic attached) - after reboot, got error 0x800f0831 for cumulative patch 2020-05 Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4556799)
which lead me to manually reset windows update by stoping services and deleting folders softwaredistribution
ran SFC /scannow - reported issues
ran DISM /online /cleanup-image /restorehealth - fixed issues (log attached)
ran SFC /scannow - now reports all good "Windows Resource Protection did not find any integrity violations." - (pic attached)
ran DISM /online /cleanup-image /scanhealth - all good (pic attached)
Checked for updates, found a few, others installed, but cumulative fails with error 0x80073701

Upgraded to 1909 using enablement package - upgrade installed
tried Windows update - same error for kb4556799 (1909)
Downloaded patch from Microsoft Update Catalogue same error...

ran sfcfix and it reports nothing broken. (see attached)

CBS.log located at - CBS.zip

Need help, please ... and thank you
