the thing is: it means that your hard drive gets encrypted. However, when that gets encrypted, besides creating a key to decrypt it, everything works perfectly. You then use that computer for 5 years and again, works great. But then the fan on the CPU gets clogged with dust and the CPU overheats and dies. No big deal, you just grab the hard drive and move it into your new computer, or you hook it up with USB to copy everything over to the new one. And that is the moment you find out it was encrypted 5 years ago. You didn’t store the key anywhere but on that disk. You can only read it with that original computer hardware because the key was made to lock that drive to that exact computer that died. And you slowly figure out that every photo, every document, everything critical to you is now protected from you and you can’t get it back.
Just as fun is making configuration changes just to upgrade your PC. Because Bitlocker uses the hardware in your computer to generate that key, some hardware changes will trigger it to need that key. Same situation where you need to revert the change to get your data.
Finally, now we need to actually bring home the issue. Drop that change into the lap of someone you know that uses a computer, but doesn’t understand the inner working of them. Maybe that’s your grandma, parent, or siblings. All of a sudden they upgrade and now have a Windows 11 time-bomb that could randomly lock them out of every file on their computer… that’s the real issue here.
Also a headache for the repair industry. If during repair the bios gets reset or the motherboard swapped, you’ll need the key to be able to boot in to windows again. And your customer is probably NOT aware.
Bitlocker is important for companies. They can have hundreds or thousands of laptops that contain files with intellectual property that could really damage the company. Laptops get stolen all the time and should be protected at the highest levels. But for normal people’s computers, the higher risk for losing data will be Bitlocker. That’s what makes this such a bad idea.
Hi, repair shop owner here.
Automatic Bitlocker encryption has been a thing since TPM 2.0 devices hit the market in 2018.
If a device is UEFI, Secure Boot is enabled, TPM 2.0 is present, and the user signs in with a Microsoft Account , then the disk is encrypted and the recovery key is saved to that Microsoft Account.
If those conditions aren’t met, automatic encryption doesn’t happen.
As long as they know their Microsoft Account Identifier, users can easily get to that key through the first search engine result for “bitlocker recovery key”: https://support.microsoft.com/en-us/windows/finding-your-bitlocker-recovery-key-in-windows-6b71ad27-0b89-ea08-f143-056f5ab347d6
We don’t really have a hard time with it - if a user provides their login PIN, a short terminal command will let us grab a copy of their key before BIOS updates or battery disconnects.
I have had very few cases where folks suffered data loss because of Bitlocker. Most of them were HP Laptops that used Intel Optane accelerated SSDs - encrypting what is effectively a software RAID0 is a recipe for disaster.
The other few had an unhealthy paranoia where they were reluctant to share anything about themselves with Microsoft, yet still decided to use a Microsoft operating system. While setting up the computer, they created a new Outlook.com email (instead of using their primary email), made up a random birthday, and did not fill in any recovery options like a phone number or secondary email. With the password (and sometimes even email) forgotten, they created a situation where they could not prove the online account was theirs and therefore could not get to the recovery key that had been backed up.
I do think that Microsoft should have this as an opt-in feature during the out of box experience, which is how Apple has it set up for Filevault and how most Linux distributions are set up. Ultimately, most users will still mash “next’ through the process and later blame the computer.
I have had quite a few clients have their laptops stolen after car breakins. Their biggest stressor was the possibility of thieves having access to the data on those machines, and the fact that we knew their systems were encrypted with Bitlocker brought them a lot of relief.
well, the thing is not everyone want to have their PC connected to MS account for privacy reason
Then don’t?
If you still want to use Windows and use their encryption solution, manually enable Bitlocker and store the recovery key yourself.
There are also third party encryption options.
Windows does not let you store the recovery key on an encrypted drive.
The rest only means, we need to deal better with our data. All the above basically also applies when you HDD or SSD dies, which can happen any time.
Backups is what you need, not an unencrypted drive.
not everyone is tech-savvy like folks on Lemmy. you can tell that to your grandma or your parents to do that to do regular backup. That is why it could cause a headache for repair business
Non tech-savvy folks aren't transplanting their hard drives in the first place.
No, but when their computer dies they'll take it to someone who does (Paid or not) to "Get their precious grandbaby photos back"
That person will inevitably ask for the key and Grandma is gonna go "What key?!?" And then when she's told all those photos are lost she's going to get pissed at the wrong person guaranteed.
These are also the same people that never change defaults soo yea this is stupid, just leave it as an easily accessible toggle for anyone who wants or needs it, but the default should be off.
They could add some kind of message that warns about this, but I think it's a better idea to encrypt by default (warning or not) rather than not... at least for privacy reasons.
It really doesn't matter what message they show during setup, you haven't worked tech support or computer repair have you?
The non-savvy users rarely pay attention to shit, a message during setup will be nothing but a blip at best in their memory by the time something happens to the computer 2-4 years later.
We've been telling non-savvy users to make sure they backup their shit for literally decades now, they still don't. Not even macOS encrypts the user data partition by default, this is gonna be a shit show and hell desks and computer repair shops everywhere are on the front line.
I consider that a separate issue.
IMO OS vendors pushing for full disk encryption is light years better than simply shrugging and saying "well people might be dumb so we shouldn't do it at all".
Just turning it on for everyone like they're planning is what I have issues with.
macOS does prompt the user to enable FileVault during initial setup, but it defaults to disabled. The other thing users do, is default to the default when they don't understand something.
So by defaulting to disabled, not many people enable FileVault without actually knowing what it's talking about. If they do know what it's talking about then all's good because they'll probably actually write down the recovery key.
MS's plan so far is "On the next update we'll just turn it on for everyone everywhere and (maybe) display a fast message with a recovery key, YOLO"
Maybe educating people about backups (in general) is a better approach than being averse to increasing security/privacy.
I still prefer MS pushing updates to people that never update vs the alternative of them getting viruses and such all the time. I just wish there was an easier way for advanced users to turn it off permanently, but it's still not impossible so I still prefer this to people not updating at all.
Like I said, there's been various backup your shit campaigns for decades now, why do you think the next time is going to be different? One of my windows PCs literally just sent a notification about backing things up (it's what reminded me of this lmao), I wonder how many non-savvy users got that and completely ignored it?
Agreed, but this is not a matter of updates, it's a matter of how they're handling this specific update. I personally just don't see the benefits of forcing FDE on for everyone outweighing the risks.
Your average home user is going to primarily get their data stolen via malware or social engineering, both of which FDE does nothing to protect against.
All we can do is try. If we warned them and they still don't do it, well you just can't fix stupid and it's not our problem anymore, plus they have bigger issues if they can't read. That's still better than doing nothing. And still better than not having device encryption IMO.
No but they’re taking it to repair shops who then find that they can’t recover their customers data because it’s encrypted and then they lose al their photos and data they never backed up, because they’re not tech-savvy.
Well, it kinda does. If you choose to print your keys, you can use print to file and safe them to the encrypted drive, if you really want to for some reason.
Yep but at this point it is obvious to the user that this is not the way it is supposed to be. When you want to shoot yourself in the foot...
This is 100% to try to force more OneDrive subs..
I wouldn't fault a casual user for not backing up their encryption key because they wouldn't be swapping hard drives in the first place. And the tech savvy people already know to backup keys.
Microsoft lets you look up your bitlocker key, this is not the catastrophic problem you've laid it out to be.
