Windows 10 21H1 update rollout is
expected in May/June of 2021 with a scooped set of features
and support for Windows Feature Experience Pack. According to
references spotted in the production builds, Microsoft has
already started preparing PCs for the update.
This time we’ve spotted some hard evidence in the latest
cumulative update for Windows 10 version 20H2/2004. With
January 2021 and February 2021 cumulative updates, Microsoft
has started adding Windows 10 version 21H1-related components
to enable support for enablement package ‘switch’.
You can verify this by manually scanning the system drive after
applying the latest cumulative update. For instance, if you
perform a simple search for “21H1”, you can already see files
for Windows 10 21H1.
While version 21H1 is going to be a minor release, it still
comes with a new OS version number and security improvements.
To enable these changes, Microsoft is using an enablement
package, which currently weighs only 22KB.
This seemingly confirms that Microsoft has started preparing
your device for the Spring 2021 update and the changes will be
triggered by an enablement switch, just like the November 2019
Update (version 1909) and October 2020 Update (version 20H2).
With the latest cumulative updates applied, downloading the
Spring 2021 update enablement package would be seemingly
instantaneous even if you have the slowest internet connection.
Windows 10 21H1 is feature-free
Unlike the October 2020 Update, which was released with a
theme-aware Start Menu, this update is completely feature-free.
In other words, Microsoft took last year’s October update,
changed the version and build numbers, and then added a handful
of minor improvements for businesses to create the ‘version
In 2019, Microsoft said that the enablement package is a “pilot
program” and it may not happen every year.
However, there remains a possibility that Microsoft has now
given up on the idea of two equally full upgrades each year,
especially after the recent issues in monthly cumulative
updates. In that case, it’s likely that we’ll see more
enablement package updates in the coming years.
