Windows Server, version 1909

Windows Server "19H2" is the server counterpart of Windows 10 19H2. Similarly to its client counterpart, and unlike all other prior feature updates, it is planned to be released in the form of a cumulative update for Windows Server version 1903. As is customary for such updates, the build number has been kept the same since the v1903 RTM, with Microsoft increasing the revision number instead.
