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.
When I switched to a new CPU I got a bit locker message and it was one of my biggest computer scares ever. I couldn’t remember if the shop that assembled my pc would have enabled it or not. And wasn’t available to contact.
I had to take a risk. If I continued there was a 50 50 chance my shit would have been bricked. Thankfully. That shop had the foresight to NOT randomly enable features the client didn’t ask for
I ran into a similar problem after a bios update.
Turns out “this update may wipe out your bitlocker key” also means “if you don’t have bitlocker turned on, it’ll just wipe out your windows key.”
