Back in January Microsoft encrypted all my hard drives without saying anything. I was playing around with a dual boot yesterday and somehow aggravated Secureboot. So my C: panicked and required a 40 character key to unlock.
Your key is backed up to the Microsoft account associated with your install. Which is considerate to the hackers. (and saved me from a re-install) But if you’ve got an unactivated copy, local account, or don’t know your M$ account credentials, your boned.
Control Panel > System Security > Bitlocker Encryption.
BTW, I was aware that M$ was doing this and even made fun of the effected users. Karma.
I’m not aware of them uploading the screenshotted data, not for now anyways.
The data is indexed and parsed somehow. The last report on it that I saw had a picture of a semi-famous person be properly indexed under the person’s name, despite it being a picture that was taken by the person talking about recall, which means the image was not public. Whatever recall was doing, it analyzed the picture, and that’s probably not a local process.
