Windows 10 version 20H2 rollout status as of March 2021

Most of the critical and known issues are now marked as ‘fixed’
or partially fixed. However, Microsoft is still aware of issues
with Input Method Editor (IME) where some characters will not
show up in your app.

As most of the bugs are now fixed,
Microsoft confirmed that it has started forcing Windows 10

For those still using Windows 10 version 1909, Microsoft has
published Build 18363.1440 (KB5000808)
and it comes with identical bug fixes. Apparently, no new
updates were released for Windows 10 version 1903, which has
been discontinued.

Microsoft is ending support for old Edge on Windows 10

After releasing these updates, the tech giant reminded both
end-users and IT admins that the old Microsoft Edge has been
retired with March 2021 Patch Tuesday update and it will no
longer receive support from the company beginning on March 10.

If you still have the old Microsoft Edge installed, the next
cumulative update will remove the retired browser and install
Chromium-based Edge instead. Microsoft recommends that old Edge
users make the switch to a supported browser to continue using
its web apps and services.

The end of support for Microsoft Edge will affect users of
Windows 10 version 20H2, version 2004 and older, which is why
Microsoft is warning users about the upcoming change. For those
that didn’t see the announcement though, Microsoft has begun
showing an “end of support” alert to Edge users telling them
that they’ll need to upgrade.
