When I downloaded this the other day, it had "uk.gov" (the way they do gov domains in the USA) so I pinged them a message saying that if they had updated the HSTS TLD's with this it wouldn't work.
On my machine there were 2 downloads for this; can't say if it's the same for Intel processors/MB's. Looking at the above link today, it seems that they have fixed it! Whoo. They've taken notice, which is a good thing.
There's also this one which you get automatically (i.e. it is foisted up you):
https://www.theregister.co.uk/2019/05/22/windows_10_may_2019_build_1903/ Customers who are inclined to take the plunge can open their Windows Update settings and select "Check for updates." If and when the update appears – Microsoft is throttling availability so the version bump may not be immediately accessible to everyone – customers can select "Download and install now," provided they're running Windows 10, version 1803, or version 1809 with the May 21 updates or later.
There's a couple of things I noticed as well which I was going to add to my original post which had disappeared in the early hours of the 7th (thanks for restoring it). Night mode has disappeared (I'm to lazy to find it) and the pictures that taunt you into wishing you were there (e.g. a tree on a beach in the Bahamas) rather than where you are blurred out on booting. There's also the change in the desktop which is what I was referring to (wrongly) about dark mode. Even on the darkest setting the taskbar is no longer back, but a dirty grey instead. As this video below states, all the settings that were previously switched off are switched back on.
