How to know if my iTunes is up to date?
Actually, Apple has only just in recent weeks made iTunes available on the Windows Store.

While it was originally planned to be released at the end of 2017 it ended up taking somewhat longer.

The version of iTunes on the Windows Store is the latest Windows version and, as you've discovered, updates are handled through the Windows Store updater rather than through iTunes directly.
