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.
How many has it protected though? Maybe 2? It’s not logical to ask the user if you want to take over their data
The push to Microsoft accounts? More people, I expect, than I’d care to admit.
Locked out recoveries, yes, but I am fairly certain that encrypting data you don’t own without notifying is some kind of crime
