Microsoft has not officially released any news about the next feature update of Windows 10. Although 21H1 references were found in the Insider test version and some Microsoft documents, there is no other official information in the next release.
As of February 15, yesterday. A blog post from the Microsoft Technology Community about the Windows Hardware Compatibility Program (WHCP) (discovered by Neowin.net) provides “official” confirmation that Windows 10 21H1 is coming and will be a minor update, as previous rumors indicate.
Windows 10 2H1 feature updates (such as 20H2) behave almost like cumulative updates. Drivers that meet the requirements of Windows 10 2004 will not require a new signature. The blog post pointed out that Windows 10 2004, 20H2, and 21H1 will all be based on the 2004 codebase.
The reason why it is so important is that over the past few years, many IT professionals have become accustomed to Microsoft releasing larger Windows 10 feature updates in the spring and then making smaller updates in the fall.
This year, the spring/H1 update will be minor. Rumor has it that in terms of new features, the Fall/H2 Windows 10 feature update will be even bigger. Among these new features, there are many UI and built-in application UI changes, and these changes are made under the “Sun Valley” codename.
Microsoft officials are currently not discussing any content in the aforementioned blog post. The Windows team has not released a 21H1 test version to the Beta or Release Preview ring, although this may happen soon.
Once Microsoft completes the finalization of 21H1 after testing and may continue to repair and update it, it will begin rolling out 21H1. The process may be similar to what happened in 20H2.
The 20H2 update was supposed to be a small update from 2004 and was activated through the “enable package”, which looks and feels like a cumulative update. For anyone running a version before 2004, the 20H2 update is updated like a regular Windows 10 feature release-meaning it won’t be so quick and easy.
