Microsoft BitLocker
Tied for most recommended of 7 disk encryptions
Built-in full-disk encryption that protects a stolen laptop's data, especially with a PIN; critics distrust Microsoft's key escrow and cite backdoor and recovery concerns.

PIN adds protection beyond TPM alone
“A vulnerability can't leak your key if the TPM doesn't know the entire key and relies on the user to supply the missing parts of the key in the form of a PIN.”
Comment from 2 Jul 2026 in “Since Linux 6.9, LUKS suspend stopped wiping disk-encryption keys from memory” “A vulnerability can't leak your key if the TPM doesn't know the entire key and relies on the user to supply the missing parts”
Comment from 2 Jul 2026 in “Since Linux 6.9, LUKS suspend stopped wiping disk-encryption keys from memory” “If you're at all serious about security and not user convenience, you deploy BitLocker with a PIN instead of TPM only.”

Good default for most users
“the default Secure Boot BitLocker configuration, for all its architectural tradeoffs, can probably be credited for an enormous amount of data loss mitigation”
Comment from 2 Jul 2026 in “Since Linux 6.9, LUKS suspend stopped wiping disk-encryption keys from memory” “It's certainly a reasonable default. People lose or have their laptops stolen much more often than they get targeted by their governments.”
Comment from 23 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops” “It's a fairly reasonable default setting for average users who simply want their data protected from theft.”

Protects data when laptops are stolen
“It protects their data in the event that someone steals the laptop, but still allows them to recover their own data later from the hard drive.”
Comment from 23 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops” “Does the encryption keep the user's data safe if the device is lost or stolen? Yes? Then it fulfills its main purpose.”
Comment from 15 Jun 2026 in “Windows 11 users are tired of MS account requirements creeping into everything” “It's a fairly reasonable default setting for average users who simply want their data protected from theft.”

Easy to set up and use
“It's a few clicks to choose to re-key and not have the key saved to your Microsoft account.”
Comment from 24 Jan 2026 in “MS confirms it will give the FBI your Windows PC data encryption key if asked” “the nice thing about Bitlocker is that you don't need to put in your key 99% of the time”

Microsoft holds keys, accessible to governments
“Microsoft cares so little about privacy and security that they would do it just to end the help customers who lose their key support tickets”
Comment from 23 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops” “There is reasonable suspicion, some might argue evidence, that Microsoft voluntarily cooperated with U.S. Intelligence Community”
Comment from 24 Jan 2026 in “MS confirms it will give the FBI your Windows PC data encryption key if asked” “Companies know that putting themselves in a position where they can betray their users, means they will be forced to do so.”

Suspected backdoor
“Bitlocker by default (although there is a convenient backdoor for high-paying customers”
Comment from 25 Nov 2025 in “Google's new 'Aluminium OS' project brings Android to PC” “while bitlocker may be backdoored in the same way, it is at least maintained”
Comment from 24 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops” “It seems undeniably a backdoor, why on earth would a very specific folder/file name and a specific boot combination just "magically" open up an encrypted drive.”

Hard to configure more securely
“It's straightforward to configure BitLocker disk encryption to be more secure, but it creates enormous headaches for admins, so they don't do it.”
Comment from 14 May 2026 in “Microsoft BitLocker – YellowKey zero-day exploit” “I've always found it silly that Microsoft's default BitLocker implementation doesn't make it easy to do the obvious thing”

“BitLocker with pin is not vulnerable to that (or any other) attack.”
“A vulnerability can't leak your key if the TPM doesn't know the entire key and relies on the user to supply the missing parts”
“how is the time limit enforced? With hardware access, it would be easy to change time or increase the clock rate”

“the default Secure Boot BitLocker configuration, for all its architectural tradeoffs, can probably be credited for an enormous amount of data loss mitigation”
“If you're at all serious about security and not user convenience, you deploy BitLocker with a PIN instead of TPM only.”
“BitLocker with a password (the equivalent of the LUKS configuration in question) does not share these issues.”
“Bitlocker is a few buttons in the UI, configurable via Group Policy”
“Except for the bitlocker vulnerability that lets someone with the physical computer bypass it.”
“Does the encryption keep the user's data safe if the device is lost or stolen? Yes? Then it fulfills its main purpose.”
“If you were using bitlocker to replace truecrypt, you'd have a boot password and this would not affect you at all.”
“There's nothing nefarious in this part, even if I think it exposes an unwisely large attack surface”
“My company doesn’t require use of Bitlocker at all, because all actual work happens on computers on-premises”

“I've always found it silly that Microsoft's default BitLocker implementation doesn't make it easy to do the obvious thing”
“so far as I know, protecting the TPM key with a PIN would mitigate this issue, but it's still bad.”
“anybody who has been paying attention has assumed for at least 20 years that all of Microsoft's shit is backdoored anyway”
“It seems undeniably a backdoor, why on earth would a very specific folder/file name and a specific boot combination just "magically" open up an encrypted drive.”
“That's something that even your Grandma can do, as opposed to installing VeraCrypt”
“back up your "full disk encryption" keys to your cloud account, completely unencrypted, and share them with the cops”
