Microsoft has released a new preview version of Windows 10 20H1 to users in the Fast channel, with its internal code name, Vibranium. Although there are no new features in this build, the biggest change occurred when the Windows 10 test desktop watermark was removed. Microsoft’s removal of desktop watermarks is usually a clear sign that Windows 10 20H1 is about to enter its final development phase, and RTM is expected to be released as early as December.
Although the RTM phase has already begun, Windows 10 20H1 still has a total of five different known issues that must be addressed for Windows 10 running in production.
For example, Microsoft says it is aware that installing a new version may cause updates to hang for a long time, and has also found issues that cause the Settings application to start only through URI, and that some external USB 3.0 drives do not respond when connected.
Windows 10 20H1 is expected to begin distribution in the spring of 2020, but Microsoft is believed to be looking forward to completing development in December.
With RTM expected to be signed next month, Microsoft will use the remainder of March or April to further refine the update experience, with the first priority being to ensure that all devices are more reliable.
Windows 10 20H1 has actually been fully functional since this summer.
