Windows client OS support period is basically 10 years from product release.
Windows Server OS had a five-year “mainstream support” and additional five-year “extended support” period.
The main difference point between mainstream support and extended support is whether or not updates are provided for non-security related issues (such as defects).

As of this writing, the easiest way to use a Windows Server 2019 is using cloud instance as an evaluation version in Azure.
