Microsoft is about to start testing Windows 10 Build 19043 (21H1)
Earlier we mentioned that the Windows 10 21H1 version to be released next spring has been finalized, and this version is upgraded based on Windows 10 20H2.
Of course, the real basis is Windows 10 20H1 Build 19041 version. Both 20H2 and 21H1 versions are minor updates and do not have many new features.
Since there is not much to test, Microsoft will not set aside too much time for this version. Microsoft will focus on major updates next fall.
The major update next fall will bring many new features and improvements, so Microsoft will spend more time on the development of the autumn version and development version testing.
Windows 10 21H1 for desktop will be build 19043, confirming once again that it will be another cumulative style release that sits on top of version 2004. It won't be a full blown OS release.

Judging from the current known news, Windows 10 Build 19043 (21H1) is just a small update with few new features worthy of attention, so it will only be released in the form of cumulative updates.
At that time, if users have already upgraded the Windows 10 20H2 version, they only need to download an update package of tens of MB to quickly update the version number.
Microsoft also plans to gradually push Sun Valley project improvements to users through the feature experience package, but more new features may be tested in the developer channel.
This small update next spring is estimated to be tested in the Windows 10 Beta channel, and interested users can also participate in the channel to participate in the test.
