Toggling on data collection without informing the user would mean billions of dollars worth of fines in Europe, so I doubt that happens regularly.

More like a few thousand euros symbolic fine and an angry letter saying "don't be an ass again pls our infrastructure depends on you" after years of blatant abuses and anti-consumer practices, followed by an ambiguous law (with positive effects affecting only european users) they will definitely not manage to circumvent withing the next week and a half. Not this time 🤡.

The problem here is the fact that most people just do not give a fuck about this; that's why there's no coverage in the (mainstream) media, why the only people who cares end up just leaving windows and why this kind of options are usually opt-out and they can actually afford to silently re-enable them cuz who's gonna check anyways? Random people ranting on meme communities about my fancy malware?

Has it been proven to happen on Windows 11? Not that I can point to specifically. 11 hasn't been in general use long enough to see a real pattern of behavior.

I was a mixed Windows and Linux user through the full life cycle of the Cortana implementation. The number of times they changed or moved Cortana related settings through the years was just ridiculous. It finally came down to having to manually change registry settings to keep it from scanning your files and messing with basic local search, and even if you did that you had to make sure the registry values were still set after version updates because they would get unset without warning.

I have no trust left for Microsoft, only suspicion.
