Tuesday, May 10, 2022, was the last update day for Windows 10 1909 (all versions) and Windows 10 20H2 (Home and Pro).
From this Tuesday onwards, both versions of Windows 10 will cease to be supported.
Microsoft has already announced this at Windows Message Center. By default, these versions of Windows 10 - at least the Home and Pro versions - should be updated automatically in the latest versions.
Those of you still using the aforementioned versions of Windows 10 will need to upgrade to a more recent version (eg Windows 10 versions 21H1 or 21H2).
However, version 21H1 of Windows 10 is only supported as Home and Pro until December 13, 2022. It is therefore recommended that you upgrade to version 21H2 of Windows 10, which will expire on June 13, 2023.
You can see the support expiration dates for Windows 10 Home and Pro on this page. Windows 10 Enterprise and Education of course have different expiration dates, which you can find at this site.
AdDuplex data for March 2022 demonstrate that:
Windows 10 20H2 still runs on 10,8% of desktops. Surprisingly, 8,1% of users of the Home and Pro versions are still running Windows 10 2004, which has not been supported for some time.
The 1909 version of Windows 10 still has 2,4% of the market share. So if you subtract these percentages from the chart below, only 55% of Windows 10 desktops run the latest versions and 19,4% run Windows 11.
Overall, 25%, about a quarter of desktops run outdated versions of Windows.
What does this mean; Either people are tired of Microsoft experiments, or they do not consider it important to run updated systems.
Personally, I believe more in the first case, especially if one thinks that after each update of Windows no one can be sure of the stability of his system.
