As you’ve probably noticed by now, Microsoft is releasing two Windows 10 updates each year. The one that most of you probably have is v. 1809. It was released in September 2018.
The next is v. 1903 (Initially released for testing in March 2019). Before it’s rolled out for the general public, it is tested by a lot of people and when the company is satisfied that it works as advertised, it is released in it’s final version.
Theoretically, this update will not be offered if your system cannot support its features. We have not seen any problem so far, though.
