Windows 10 is an evolving platform and Microsoft occasionally
adds new features or adjusts the behaviour of default features.
Like the current Windows 10 October 2020 Update, Microsoft is
believed to be working on another scoped release of the
operating system with a limited set of features to improve the
According to sources familiar with the development, Microsoft
is about to finalize the RTM candidate for Windows 10 21H1. In
fact, it’s possible that Microsoft has already finalized the
RTM build, which makes sense given that Insiders are now
frequently getting minor updates.
Windows 10 21H1 coming next year is built on top of the October
2020 Update, which is based on the May 2020 Update. Microsoft’s
plan is to backport some minor improvements and features to the
existing October 2020 Update and release the modified/final
version as ’21H1′.
Windows 10 21H1 update will also be delivered and installed
like a monthly update as part of an ‘enablement package’. This
implies that the installation process will be quick and simple,
and there won’t be any big leap in the OS build numbers.
This is because the Windows team is busy with the development
of Windows 10X and Windows 10 21H2 (fall 2021 update).
So technically, Windows 10 21H1 is pretty much the same as
Windows 10 October 2020 Update (version 20H2), and this is the
reason users won’t notice any big difference.
Microsoft could use the new ‘Windows 10 Feature Packs’ to
deliver improvements for some apps and OS independent
features later. Microsoft has already backported the Windows
Feature Packs to the October 2020 Update in the beta channel of
the Windows Insider program.
Also, you may not see the Windows 10 21H1 update until the
spring of 2021 (April-May) right away. Additionally, some
devices might have a compatibility issue and they’ll be blocked
from receiving the update.
In the spring, Microsoft is also expected to announce two new
services – Cloud PC and Project Latte.
Cloud PC aims to bring your desktop apps to Windows 10X via
Microsoft’s Azure cloud technology and
Project Latte enables support for Android apps via Windows
Subsystem for Linux.
The ‘real’ feature update is codenamed ’21H2′ and it is
expected to arrive in the second half of 2021 with rounded
corners, improvements to Start Menu, Action Center, and more.
