Will it be Windows 12 or Windows 11 24H2?

It isn't apparent whether the new version of Windows will be called Windows 12 or Windows 11 24H2. I guess we will know for sure later this year.

Windows 11 version 24H2: New features, next-gen AI PCs, and everything we know so far

I have looked at the Windows Insider website and it looks like they are testing some features that may end up future versions of Windows (Windows 12?) in the Canary Channel. Is anybody on this forum testing builds in the Canary Channel? The latest is "Windows 11 Insider Preview Build 26020" that was released on January 3, 2024.

Build 26020 (Canary Channel)

Yes, probably the Windows 11 Canary versions are a preview of Windows 12 features (such as UEFI only installation, Legacy mode is dropped, but there is a workaround), but I think it is too soon for a release version. Probably after Windows 10 EOL in 2025.

I've downloaded and installed 24H2 on several of my OLD PC's, that Do have AMD cpu's, and they run FAST, and faultless.
On some others, it will install but then won't boot.
Those are the much older PC's with Intel CPU's.

Hope it will be 12 as it might confuse some new members or guests like windows 8.1 did at first.

Yeah, that was a real naming mistake. Win-9 would have been nicer. But either way, the program itself was GREAT!
