There's a cumulative update for win10 1809 [fall, 2018], and another for win10 1803 [spring, 2018], that did not show up automatically for me at least -- had to manually check for updates -- that includes the new option of deferring feature updates, which is what Microsoft calls their win10 version upgrades, along with several other fixes.

What Microsoft says it's going to do, is to start later this month rolling out the notice via Windows Update, that the upgrade is available. It'll start with models of PCs & laptops that haven't reported problems with the upgrade so far, expanding the list of who can get the upgrade as fixes become available. In my experience, if your device isn't on the list as having problems with a win10 version upgrade, and you don't have any of the black listed hardware or software installed, you'll get it sooner rather than later. Those still running the spring 2018 version of win10 [1803] this June will start getting notices to upgrade, as support for 1803 will end in the fall -- since the option in Windows Update to defer version upgrades is brand new, no idea if or how the upgrade might be forced.
I've got the 2 tablets, the mini PC, & my wife's laptop to check, but I'm afraid they all may have one of the hardware components that's black listed so far. The one I'm most worried about is the problem with Qualcomm WiFi, because that's the only one where Microsoft doesn't say a fix is coming. The only problem I've experienced so far with the 2 PCs is that the icon for Notepad on my desktop changed to the generic shortcut icon -- when I went to fix it in the shortcut's properties, it reported that Notepad.exe doesn't contain an icon, so I had one of the alternatives Windows offers. [Yeah, that's at the bottom of the list when it comes to importance, and *that's* my point. ;) ]
There's little if any practical reason for me to jump on the 1903 upgrade as soon as it was available -- for me it's more a psychological thing of maintaining control, vs. the unknowns of automation, specifically in this case the timing. I'd rather get it out of the way rather than worry that it'll hit at the worst time possible. But that's me, and you may find a reason to get exited about the new version.

Maybe the best & the worst feature of the Windows 10 setup routine is the same thing... And it's changed a bit over the years with each win10 version as Microsoft struggles to get it right. When you do an in-place upgrade, win10's setup will often try to reuse some working drivers -- which ones & how aggressively varies with the win10 version. The driver situation is a mess nowadays, with the odds being pretty darn good that you will not ever find an updated driver for some of the components your PC or laptop uses. Reusing drivers in that case can be critical. But sometimes updated drivers are available, sometimes Microsoft does not have them, and sometimes reusing the old drivers breaks Windows 10. And sometimes drivers are updated during the course of using one version of win10, but that updated version is incompatible with a later version of win10, again breaking Windows.
My personal advice is to perform a disk image backup before upgrading win10 versions, because sometimes a win10 in-place upgrade or a fresh install just doesn't work, and the [thankfully] few times I've experienced this, simply starting over, things worked just fine. When an in-place upgrade fails, setup will roll things back & try again -- I've had zero luck using that approach. I also suggest making a copy of the C:\Windows\System32\DriverStore folder, ideally when you 1st get a device... Every driver your copy of Windows uses [& several it does not] is in that folder. If you want, or have to do a fresh win10 install, the only source for one or more needed drivers may be in that folder. Doing an upgrade or a fresh install, if you have to go back to an earlier driver version -- and I've had to a few times -- again that may be the only source.
That said, at least according to this Windows Central article, there are all sorts of things that can go wrong installing or upgrading win10. I actually found the list more than a bit scary -- if I'd read it before I installed my 1st copy of win10, I probably wouldn't have. :0 Hopefully you can ignore it, but if you have problems & need a reference for an error code for example, maybe it'll help...
