After Windows 10 2004 (also known as the May 2020 update) began to be officially pushed, Microsoft also provided Build 19635 to Insider testers for the Fast Ring channel. The first preview compiled version of the newly developed branch’s change log is very thin, so don’t expect it to bring new features or major improvements, as it focuses on bug fixes and other minor revisions.
Windows 10 build 19635 brings two major improvements, one of which is related to cellular data. Previously, this feature was not available on some devices, but the affected user base is not expected to be large.
The second is the problem with some system configurations where the display may continue to flash. Both of these conditions are expected to be mitigated from build 19635, and there are four known historical legacies of the Insider beta in the preview.
If all goes well, Windows 10 20H2 is expected to be released this fall. As in last year’s 1909 update, this modest revision is expected to be officially available around November (or version 2009).
As for the Windows 21H1 major release update, it’s clear to wait until next spring. However, there have been rumours in recent days that it could start insider testing as soon as next month.
