Hold up, why is 21H2, 22H2 of Windows 11 currently gone?

Hold up, why is 21H2, 22H2 of Windows 11 currently gone? (To not think I'm using it, I use Windows 11 25H2 Home Single Language). I have just watched a video of all EOL messages and none of the surprised me, except for the Windows 11 21H2/ 22H2. Is this even official?

That means the only ones that exist is 23, 24, 25 and 26H2. Please explain why.

Reply ASAP,

Hello Huy Dat Nguyen,

Windows 11 versions 21H2 and 22H2 have not been removed or declared unofficial. They are previous Windows 11 releases that have reached the end of their servicing lifecycle.

Each Windows 11 feature version is supported for a limited period. For the Home and Pro editions, version 21H2 reached the end of servicing on October 10, 2023, while version 22H2 reached the end of updates on October 8, 2024. Once a version reaches that point, Microsoft no longer provides regular security and quality updates for it, so users are encouraged to move to a newer supported release.

Therefore, “end of servicing” does not mean those versions never existed or that their documentation has disappeared. Their update-history pages remain available, but they are no longer considered current supported versions.

Since you are already using Windows 11 version 25H2, this does not indicate a problem with your installation.

You can verify the information through Microsoft’s official pages:

I hope this helps clarify the difference between an older Windows release and a currently supported one. Thank you so much for your understanding.

Yes that is correct. If you look at the Lifecycle link you will get the full details. Windows 11 24H2 ends support in 3 days.

Yes, it is official.

Windows 11 feature versions are serviced for a limited time, not indefinitely. The documented servicing timeline for Windows 11, version 22H2 is:

Windows 11 Pro: 24 months from release
Windows 11 Enterprise: 36 months from release

That is why older releases such as 21H2 and 22H2 eventually reach end of service and are no longer the current supported versions.

For 22H2, Microsoft also published that:

Home, Pro, Pro Education, and Pro for Workstations editions receive non-security preview updates until June 26, 2024
Enterprise, Education, IoT Enterprise, and Enterprise multi-session editions receive non-security preview updates until June 24, 2025
After those dates, supported editions continue to receive only cumulative monthly security updates for the remainder of support

So 21H2 and 22H2 are not “fake” or unofficially gone. They are older Windows 11 releases that have aged out of active servicing.

The context provided does not state that only 23H2, 24H2, 25H2, and 26H1/26H2 “exist.” It only supports that older versions like 21H2 and 22H2 have update-history pages and that 22H2 has defined servicing/end-of-update milestones.
