Microsoft is preparing to release new cumulative Windows 10 updates for all versions of the operating system that continue to receive security updates.
The release will take place as part of the Patch Tuesday April 2021 cycle and will, of course, focus on security enhancements.

Needless to say, these cumulative updates should be installed as soon as possible by all users, although as we have learned this is not the best idea sometimes as various issues are constantly encountered.
The Patch Tuesday cycle for April 2021 will also bring additional improvements for Insider builds and this time, the mood is especially important as Microsoft prepares to release another feature update for Windows 10.
Είναι η έκδοση 21h1 των Windows 10, η οποία σύμφωνα με το τυπικό πρόγραμμα κυκλοφορίας της Microsoft θα κυκλοφορήσει πιθανότατα τον επόμενο μήνα.
Version 21H1 of Windows 10 will be released more to improve operating system performance and less to bring new features.
We will publish the list of cumulative updates for new versions of Windows 10 tomorrow, when knowκινήσει η διάθεση και θα σας ενημερώσουμε σε περίπτωση που μπορεί να αντιμετωπίσετε problems.

Hello!
I have a Lenovo G40-30 laptop with Windows 10 Home (I am still in version 1909).
I received the message:
“Update features for windows 10 version 2004
The May 2020 update of windows 10 will be available soon.
When it is ready for your device the update will appear on this page. ”
Even if the upgrade of May 2020 comes to me and with a deadline for 1909 to be in 1 month, can I have a problem or will it be done by then?
Thanks!
Logically according to the company there should be no problem (https://support.lenovo.com/ca/en/solutions/ht510448-lenovo-devices-tested-for-windows-10-version-2004-may-2020)
Of course you can download the ISO you are interested in and run an upgrade yourself.
