Starting with this assembly, Microsoft decided to change the previously known version number 2003 to 2004. This decision is due to possible confusion with previous product names (for example, Windows Server 2003).
Recall that, perhaps, for a similar reason, we did not see the version of Windows 9. To avoid confusion with the common name for the operating systems Windows 95 and 98 (Windows 9x), after the version of Windows 8.1, the new Microsoft operating system immediately received the tenth number.
Check Windows Insider Settings
In the near future, insiders on the Early Access channel will again receive assemblies from the RS_PRERELEASE development branch (Windows 10 Manganese or 20H2 update) instead of VB_RELEASE. It also means that the desktop watermark will be back with new builds. As is usually the case with pre-builds, these builds may contain errors and will be less stable. It is time to check your Windows Insider Program settings and switch to the Late Access channel to stay on 20H1.
Go to Settings > Update & Security > Windows Insider and make sure you select the preferred priority for receiving updates.
Insiders on the Early Access channel who decided to stop receiving Windows 10 Insider Preview builds will automatically be switched to the Late access channel when the next Windows 10 20H2 update becomes available in the Windows Insider program settings. They will remain here until the final release of Windows 10, version 2004 (20H1).
