You think? Assuming we're just talking about the Microsoft product, I only use it at work, and I'm not signed into my Xbox (Microsoft) account there. I am signed into the corporate Intranet, which I use to log on, and I can use it to access Office Online, so maybe they're synced through that? OneDrive is installed as it is part of Windows (then again, so is the Xbox app) but I can't do anything with it. It says my account isn't provisioned for it and I just get a blank screen. Same with Copilot — I've tried it. The hardware is capable, I suppose it is technically a "Copilot PC" though it isn't branded as such... but it won't run without a Windows account. And I'm not using my personal one.

I guess I can test it by logging onto another workstation and opening Sticky Notes.

Unless you're implying Microsoft just stores all kinds of data Windows can find in the cloud... that would not surprise me. You'd be saying every company that uses Windows has their trade secrets and whatnot in Microsoft's cloud. I would not doubt that either, fuck Microsoft and all that, but I kinda doubt a lot of companies would just let that go. I think by using our own intranet for a lot of stuff, we sidestep most of that. I'm not really sure though. I also don't care that much. I don't have a stake in the company, after all. And I'm going to try to be a responsible steward of the information I do have. If I had Copilot access, for example, I wouldn't tell it anything personal, private, or confidential. But as far as what Microsoft actually does? I figure I have very little power over that.
