    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.

    Bit late to this thread but I know a few commands that might help if you're stuck:

    manage-bde -off C: (or any other drive) This decrypts the volume and turns off bitlocker

    manage-bde -lock/unlock

    manage-bde -protectors -get C: (or any other drive) This displays your 48-digit key. I suggest you store it somewhere, just to be safe.

    Get-BitlockerVolume reveals which of your partitions are encrypted with Bitlocker.

    Disclaimer: I am not a terminal nerd, I just had similar problems years ago and went down the rabbit hole, used these commands and turned off bitlocker permanently. I don't use windows anymore, but when I did, it didn't cause any problems with bitlocker after this. If you're concerned about your un-encrypted hard drives, consider using Veracrypt (carefully!) or similar open source encryption software.

    Alright, lol, I'll be the guy

    Hey OP, ever heard of Linux?

    [–] andybytes@programming.dev 23 points 22 hours ago

    Windows is the virus.

    [–] stonedtemplepilot@lemmy.world 4 points 15 hours ago (1 children)

    I mean you can write your Bitlocker key down and store it safely or put it somewhere else safe.. Lol

    [–] Sydnxt@lemmy.dbzer0.com 7 points 13 hours ago

    The main problem here is Bitlocker is being turned on by default on fresh 24H2 installs, most people that don't know how to bypass the online account requirement are making burner Microsoft accounts (Boomers), therefore do not know the credentials in 3-4 years when their computer needs a repair.

    Fuck Microsoft.

    I remember back in highschool a buddy encrypted his harddrive, didn't backup his key. He Lost ALOT when I upgraded his comp

    [–] Aganim@lemmy.world 6 points 13 hours ago* (last edited 13 hours ago) (1 children)

    But how is that relevant to your 'Fuck Microsoft' if he knowingly encrypted his device, which is how you make it sound?

    I've enabled FDE on one of my Linux devices, I've already had to mount the filesystem in a rescue environment once because a failed update caused the system to be unable to boot. I would also have been hosed if I had lost the encryption key. Ok not really, because that's what backups are for, but you hopefully get the point.

    [–] AnohterDumbUserName@lemmynsfw.com 2 points 9 hours ago (1 children)

    From what I gather though other memes, It looks like Windows 11 is enabling Bitlocker by default.

    [–] Aganim@lemmy.world 2 points 6 hours ago

    I know, and the 'fuck Microsoft' is completely warranted for that. But shouting that and then coming up with a story where somebody enabled it themselves and subsequently lost their key, that doesn't make a lot of sense. Unless it was to illustrate the dangers of FDE, but in that case the point could have been made a bit clearer.

    [–] gnygnygny@lemm.ee 1 points 9 hours ago

    That's not a Microsoft issue. Loose your key and the door will stay close whatever it is.

    [–] MystikIncarnate@lemmy.ca 6 points 22 hours ago

    I've been preaching about this for a while. Many modern systems are getting bitlocker turned on by default.

    If your system gets messed up, or simply won't start because of some security vendors bad update, goodbye data. You need the recovery key, and if you don't have it, you'll never see your bits the the correct order again.
