After a little bit more than a month and half after quickly pulling out Windows 10 1809 and Windows Server 2019, they are now available again through the usual channels: MSDN (by the end of this week), VLC, Media Creation tool or WindowsUpdate (this one may take a little bit more time to be available to everyone).
In addition, some additional complements:
- Windows Assessment and Deployment Kit (ADK) for Windows 10 1809 is available here https://go.microsoft.com/fwlink/?linkid=2026036
- Windows Preinstallation Environment (PE) add-on for Windows ADK – starting with Windows 10 1809, Windows PE is now a separate component for ADK – is available here https://go.microsoft.com/fwlink/?linkid=2022233
- Group Policy References for Windows 10 1809 (including the Administrative Templates [ADMX]) is here https://www.microsoft.com/en-us/download/details.aspx?id=57464
RSAT is no longer a separate download and is available as a Feature on Demand – you can enable just the RSAT tool you want/need. Don’t forget neither you can also use the Windows Admin Center to manage your servers.
