After announcing that Windows 10 May 2019 Update(19H1) is ready for broad deployment, Microsoft seems to be in the process of laying the groundwork for the release of Windows 10 19H2 Update.
Microsoft has made the Windows 10 version 1909(19H2) Build 18363.356 ESD available on Windows Server Update Services server (WSUS), which is a solid hint that the Build 18363.356 is the RTM Build. Of course, you won’t be getting Build 18363.356 as the final Build, because Microsoft already released Build 18363.387(higher Build number) to the Release Preview ring.
The arrival of Build 18363.356 ESD on WSUS means that Microsoft is adding the finishing touches to the Windows 10 19H2 update and will release it to the public soon. The Windows 10 19H2 Update, however, is yet to get an official name, but as per Microsoft’s naming convention, it could be called Windows 10 October 2019 Update.
It’s worth noting that users running the Windows 10 May 2019 Update will be able to install the 19H2 feature update like a monthly cumulative update. However, Users who are running any Windows 10 version older than Windows 10 May 2019 Update are not going to get the 19H2 update like a monthly cumulative update, meaning that the way of updating to Windows 10 19H2 will be the same as before for users running Windows October 2018 Update or older.
Microsoft will be doing a lot of announcements next week and one of the announcement could be related to the release of Windows 10 19H2 Update to the public.
