How to get the Windows 10 May 2019 Update version 1903

No, looking at his Computer spec he's got Emsisoft Anti-Malware and Windows Defender running.

My money is on a missing Servicing Stack that update is not picking up on.

It could be since there are many reasons why 1903 is not offered and generally MS won't give a clue about what it is or they are.

Not sure what "ESET" is, I use Emsisoft as my AV.
I'm waiting for my Emsisoft subscription to run, because it's not worth the $40 USD I paid for it.
Once that's over and done with, I'm going with Windows 10 native protections entirely.

ESET is another type of A-V on the market. If I am not mistaken, there are Free and Paid versions. About your decision to run only WD, that is exactly my case right now; only have WD as the only line of Defense. Once in a while I would run adwCleaner from MBAM just to check out in case WD would miss something.

I have Eset and 1903 Release Preview was offered to me a long time ago. As well, all the CUs have been offered.

That is probably why "A long time ago" as you mentioned. This seems very recent with TrendMicro (ESET):

We recommend to hold off on updating Windows to the new release until after the OfficeScan/Apex One agents have applied the appropriate patch, as doing so beforehand may result in incompatibilities. Incompatibilities may include performance issues, program crashes, and even system BSoDs.

Support for Windows 10 compatibility - OfficeScan / Apex One

What the heck is "OfficeScan / Apex One" never heard of it!!??

Good question!. I cannot really venture into answering this with certainty, but in all likelihood it seems to be the system responsible to patch their software.
