Windows 11’s next big update just moved a step closer to fruition, perhaps, given a rumor that Microsoft has just pushed out a new preview update that represents the 24H2 release.

The 24H2 update is due later this year, most likely in September, but the twist is it’s expected to initially arrive – in a slightly different form for certain devices (we’ll come back to exactly what we mean here) – around the middle of 2024.

The preview version of Windows 11 we’re talking about is build 26100 and we’re told by reliable leaker Zac Bowden (of Windows Central) that this is the RTM build for the 24H2 update (which Bowden predicted would arrive in April).

RTM means 'release to manufacturing' and it translates, as the name suggests, to mean this is effectively a finished product – with caveats that we’ll come back to shortly – that Microsoft is sending out to PC manufacturers to put on their devices (and test before that hardware hits the shelves).

Some PC makers may have received this RTM build already, or they are about to. In short, this is a positive sign that Windows 11 24H2 is progressing on track with its purported release schedule as aired via the grapevine.

The mentioned caveat-laden twist is that this initial hardware in question is AI PCs with Snapdragon X Elite chips, which are based on ARM architecture (quite different to AMD or Intel x86 CPUs). Because these Snapdragon chips are different to the general norm they need the new Germanium platform that Windows 11 24H2 is built on to work, so Microsoft is technically deploying the new version of the OS with these AI PCs which are expected to debut in June.

However, that particular Windows 11 24H2 build won’t have any of the new features touted for the next big upgrade. It’s just going to be much the same as what we have now with Windows 11, just with that new underpinning Germanium platform for ARM-based chips.

Microsoft will finalize the fully fleshed out 24H2 update, with all its new features added on top, in July; or that’s the predicted timeframe by Bowden. And then after final testing, the full 24H2 update will roll out to everyone on Windows 11 in September. Including those Snapdragon X Elite PCs, of course, who won’t get all the new features until everyone else is receiving them.

Hopefully we’ve made that clear enough. But it’s true that this is all rather more complex and convoluted than the usual straightforward deployment of a Windows annual feature update.

The long and short of it is that things appear to be on track, but nobody will get the full Windows 11 24H2 update until September 2024 (or around then). And while new AI PC buyers this summer will get a Snapdragon-powered laptop with 24H2 on board, this will be just the skeleton of that version, as it were, and all the meat (new features) won’t be added until everyone else receives the update in September(ish).
