A new mandatory security patch for Windows 11 was released last Tuesday, known as the update KB5046633 for Windows 11 23H2. Users who have installed the update, however, are reporting a strange message appearing ever since.

Windows Update appears to be warning of the end of support for Windows 11 23H2 and asking you to download a newer version of Windows to stay up to date. It’s as confusing as it sounds. Read on to understand what is happening and what you should do.

End of support for Windows 11 23H2?

This news is justifiably surprising, as Windows 11 23H2 is still expected to remain supported – with both security and feature updates – until November 11, 2025. (Official confirmation on this page.)

A Microsoft support representative confirmed with Windows Latest that this message is indeed an error, stating, “This is just a reporting error on our part.” The issue is already under investigation and will be addressed in a future server update, likely within a week.

In addition to this warning about the supposed end of support, users are also given the option to check for updates, which has raised eyebrows because this patch – update KB5046633 – is already the latest version.

What you can do if you are affected

If you see this warning, it may help to log off and restart the system. Otherwise, you can wait for the server fix to take place, at which point it should go away. It is still unclear how this erroneous message appeared.

Note that there was indeed an end-of-support message in early October, but for Windows 11 22H2 users. If you are still on Windows 11 22H2, you should upgrade to a newer version as you will no longer receive security or feature updates.
