Windows update fails with Error 0x800f0900

Unable to install both latest cumulative updates.

The installation of 2019-04 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4493437) failed yesterday with Error 0x800f0900 and today the installation of 2019-05 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4499167)
failed too with same Error 0x800f0900.

I ran the Troubleshoot app on Windows Update. It fixed Service registration missing or corrupt. However, running Windows update still failed with same Error 0x800f0900.

Restarted the computer several times and search the internet for fixes without success.

Please help. Thanks, Blaise
