Windows 10 May 2021 Update, otherwise known as version 21H1,
has been cleared for deployment, meaning it will be now offered
to users when they manually check for updates.
Windows 10 version 21H1 was released to consumers on May 18 and
it was rolling out slowly around the world. Normally, Windows
bugs and glitches prevent broad deployment of Windows 10
updates, but since the May 2021 Update is essentially based on
October 2020 Update (version 20H2), there are no critical
issues in the update.
In multiple tests, we observed that the May 2021 Update
(version 21H1) is now offered to everyone running the May 2020
Update (version 2004) and October 2020 Update (version 20H2).
The number of devices which can be offered the latest feature
update has been increased by Microsoft in June.
If you want to
download and install Windows 10 May 2021 Update, simply
head to Windows Update and check for updates. Under the
“optional updates” section, click on “Download and install” to
begin the download of Windows 10 version 21H1, which requires
one reboot to finish the installation.
We also noticed that Microsoft quietly updated its
documentation on June 2 to announce the wider availability of
the feature update. The company stated that it is now using its
machine learning and artificial intelligence methods to
automatically upgrade devices running version 2004 to version
“We will continue to train our machine learning through all
phases to intelligently rollout new versions of Windows 10 and
deliver a smooth update experience,” Microsoft noted.
If you still can’t see the update for some reasons, you’ll just
need to wait for a few days/weeks. It is also possible to force
the installation via Media Creation Tool or Windows Update
Assistant. If you want to start fresh, you can follow our guide

The latest May 2021 Update has a few known issues, but
fortunately, the bugs haven’t reported widely and workarounds
are available if you do run into gremlins after upgrading.
For example, a bug in Windows 10 May 2021 Update or older could
unexpected audio issues. As per a new advisory, users can
hear high-pitched noise when using 5.1 audio with certain
settings. The issue affects certain apps, audio devices and
settings combinations only.
If you run into audio issues, Microsoft recommends switching to
Spatial sound settings, such as Dolby and Windows Sonic.
The second known issue prevents the automatic Furigana
input/conversion feature from working in some apps.
