The Windows 10 21H1 “Spring 2021” update is most official and is available to millions of users through Windows Insider. It brings some improvements as well as new features for Windows Hello.
Unlike the Windows 10 version update 2004 of the previous year, the new upgrade is not a huge overhaul of the operating system, as the company wants to focus on "quality improvements" and "a small set of features".
Later today, you'll be able to download and install the Windows 10 21H1 update from the channel Beta, but as mentioned above, you might not get excited.
The fact that the 21H1 version is relatively small in terms of new features could be a good thing. This will allow Microsoft to add all new features to the update Sun Valley which is rumored to be released in October 2021.
In a press release, Microsoft states that Windows 10 21H1 will be released with maintenance technology, which was used for October 2020 Update and November 2019 Update.
Although the full changelog is not currently available, Microsoft promises small new features, security changes, and quality improvements.
How to try the Windows 10 21H1 update
Microsoft releases the feature update to Insiders, so it should appear as an optional download if you're in the Windows Insider program and subscribed to the Beta channel.
If your device qualifies, you will see an update called “Feature update to Windows 10, version 21H1” later today.
