I get bogus "Your version of Windows 10 is out of date" messages.

Hello,

I just did a clean install of Windows 10 64-bit on an AMD system and then did all updates up through version 1903. After that I uninstalled Windows 10 Update Assistant just to get rid of the Windows10Upgrade directory. Everything seems to work perfectly fine except that instead of the lock screen is displaying the typical blurb about the picture that is there it displays the words "Millions of people have installed the latest Windows 10 update..."

When I click on those words and enter my password it takes me to a secure microsoft.com page that says "Your version of Windows 10 is out of date" and provides an "UPDATE NOW" button. When I click that button it provides me with file Windows10Upgrade28088.exe. When I run that file it reinstalls Windows 10 Update Assistant and the Windows10Upgrade directory and thanks me for updating to the latest version of Windows 10. However, I continue to get the same message on the lock screen and indication that Windows 10 is out of date. I've tried doing the standard Windows Update search too but it doesn't indicate that any updates are available.

How do I convince Windows that it already has the latest update?

Thanks,
Ray
