So I installed these CU19 KB on my Exchange 2016 servers.
Exchange2016-KB5000871-x64-en
Exchange2016-KB5001779-x64-en
How can I verify that they are installed now?

I found this that gave me what I needed
https://docs.microsoft.com/en-us/Exchange/new-features/build-numbers-and-release-dates?redirectedfrom=MSDN&view=exchserver-2019

I download the https://microsoft.github.io/CSS-Exchange/Diagnostics/HealthChecker/ and ran that on my Exchange servers.

Easiest way may just look under the Control Panel / Programs and Features/ installed Updates

Sorry, my apologies for the wrong information.
Please use this command instead:
