I'm very excited for this feature and bought a Copilot+PC for this feature.

I spend so so much time looking for information I saw in the past...a document, a conversation, a website, etc. This will be a big time saver and have a ton of utility.

To those that are scared of it: don't use it. I can make my own choices.

Yeah, Rewind is super useful and this is just a clone of it for Windows. It's your browser history but works for everything.

You can not trust Microsoft and that's totally valid, I don't, but I also don't use Windows. It's a really stupid line to draw if this is the straw. They control the entire OS, basically force online accounts, have been confusing the line between remote and local storage for years, exfiltrate local searches to Bing, track everything for in-app and in-os advertising and send undisableable telemetry. Does this feature just lay bare the reality you've been living under for years?

I think it's not that people don't trust Microsoft with their data (they obviously do if they use Windows, as you note), it's that they don't trust Microsoft to have performed basic diligence on data control within this feature.

> it's not that people don't trust Microsoft with their data

Let me fix that... People don't trust Microsoft.

[woodruffw]

Per the GP, there's a great deal of evidence that people have a revealed preference for trusting Microsoft, if they're already in the Microsoft ecosystem.

(I don't particularly trust Microsoft, but I'm also not in their ecosystem.)

[indymike]

This assumes those people have a credible alternative, which in most cases they do not.

25 years ago (or even 15 years ago), I would have probably agreed. But I don't think that's true anymore; to my understanding, students in public schools are equally as likely to use Chromebooks as they are to use Windows or Mac machines.

It's on the user side of the airtight hatchway, that's good enough. If you could read my browser history you could read this and vice versa.

[woodruffw]

If I remember correctly, one of the original concerns was that the feature didn't respect user boundaries on the host machine itself. In other words: multiple users sharing a machine could inadvertently (or intentionally) retrieve information about each other.

That would be a straightforward example of "can't read the browser history for a user, but could read it indirectly via the agent."
