Windows Core OS is different from Windows Server Core.

Santorini is the codename for Microsoft's forthcoming 'Windows Lite' OS designed for laptops and 2-in-1s.

Microsoft is building out Santorini as the version of Windows Core OS that runs on consumer and education foldable PCs, laptops, and 2-in-1 tablets. It may even eventually show up on Microsoft's mythical Andromeda device. It's a new take on what Windows can be, introducing a brand new user experience that's a little more like Chrome OS and less like old-school Windows. It has deep ties with web experiences and puts universal Windows apps front and center, with the ultimate goal of having everything in the Microsoft Store runnable on Santorini.

Santorini features a centered taskbar experience, similar to that on the Surface Hub 2X. There's a simple app launcher that doesn't feature live tiles, which lists your installed apps from the Microsoft Store or pinned websites. I'm also told that Windows Sets has a pivotal role in the overall Santorini experience, with apps and websites running under tabbed windows that also get grouped as such in the taskbar.

Didn't they say recently that Sets is not being developed, partly because it was too closely tied to non-Chromium Edge? Which makes me wonder how much else of that is still being developed.

I think Sets is still being developed, just not in the way originally intended. [1][2]

Ah, I missed that followup.

Thanks for the clarification.
