The original source for that is an internal presentation with poorly-worded language that said Windows will “move” to the cloud, the whole presentation slide makes it clear they’re talking about Windows in the cloud as an option: https://www.theverge.com/2023/6/27/23775117/microsoft-windows-11-cloud-consumer-strategy

Forcing everyone to stream Windows from a cloud server would not work well for the vast majority of PCs and internet connections. Microsoft isn’t dumb, they’re not going to try that and lose even more market share to Apple. I was linking to the article to show the correction, the original article was junk based on nothing and shouldn’t be taken seriously.
