Well... until at least October 14, 2025, according to
Microsoft. Mind you, I don't actually think that Microsoft is going to leave their "legacy" customers entirely in the lurch, when that day comes. I've commented at length on this topic elsewhere, but the short version is this: There are just far too many Windows 10 customers who are still being blocked from upgrading to Windows 11, due to the TPM requirement -- and not
just Mac users, either. Microsoft has to account for that issue, somehow. Whether it will be by continuing support for W10 beyond 2025 or by relaxing the W11 requirements so that more people can update (or by some combination of both) remains to be seen.
But I'm largely in agreement with the marshmallow; I very much doubt that they're going to take any meaningful action against users who manage to successfully update to W11 on "unsupported" hardware. Can you imagine the aftermath of such a thing? They'd be absolutely skewered by every single tech reporter on the planet, just for starters... and that's to say nothing of the vitriol that we'd likely find in various comment forums.
