If you redirect the profile to the D : drive (good luck actually getting that to fully work) ....
Weren't you just arguing that you trust MS more than me
No, if anything, I was arguing that I I trust them the same as you.

Is it right? Should we quit and work for a place that values "pure IT" ... sure, but I bet more companies do weird stuff and use weird apps that might write to the C drive than not.
So you are saying that you think that it's acceptable to have known security design problems with apps exposing user data, but then encrypt them to ignore that there are more fundamental security issues?
What software do you think people have that is doing this? Any why would a shop that claims to be super concerned about security choose to deploy them?
You say that I look at the world from an ideal standpoint, but I'm just looking at it from a logical one. Logically, if you care about security you care, and if you don't, you don't. The encryption is just a farce in your logic and IT isn't there to do a good job, just to cover up stuff.

Now you've lost me though - profile redirection causes all kinds of problems. Can you make it work, yes. Is it easy ? Heck no. My own personal experience also says it's not that stable either, but I'm willing to take the blame on that bit if needed.

@scottalanmiller said in supporting an office of computers with full drive encryption:
the files written to the disk are encrypted (or not written at all.)
OK I think I see what Scott is writing here. IE has a setting:
https://i.imgur.com/audFdVc.pngThis will prevent encrypted pages from being saved to disk.
But my question to @scottalanmiller is - What about confidential information that is viewed over a non encrypted connection?
Is there a way to make IE, and all other software, not write temp files to the drive at all? And of course, I never saw any discussion at all about the page file, which as far as I know can only be encrypted when using full disk encryption.
Not that I know of, but you can make sure that it only writes to the encrypted user drive.
how?
By putting the user's directories on D... the thing we are discussing.
Not trusting Windows is a different matter. If you feel Windows simply can't be trusted, the only answer is really to leave Windows.

I do trust Windows, let's just assume that they aren't doing anything wrong. I still don't know how you access an encrypted location during logon so that Windows can load the profile. How are you accomplishing this?

@NerdyDad said in supporting an office of computers with full drive encryption:
Coming into the conversation late here.
I have a full enterprise where most, if not all, of my laptops are bitlockered before they are deployed. Security keys are stored in the TPM for boot decryption. I also hold the kyes to the encryption on an IT controlled drive.
There is also a boot up password that must be entered by the user when the boot the computer up from cold. If they are rebooted, the startup password is bypassed automatically by the bios/uefi.
I've never played with Bitlocker. I was unaware that if you had a TPM that you could required a boot time password still - is that password used to unlock the TPM? How do you manage that password? What if a user forgets their TPM password?
The boot time password has nothing to do with the TPM or bitlocker but is more of a BIOS/UEFI setting to allow access to the hard drive to boot. You could do the same thing to a computer that is totally un-bitlockered.
Huh - so you've added yet another level of complexity. How do you manage these? Do all users have a different BIOS/UEFI password? Do the BIOS/UEFI allow for both a user level password (for disk booting) and an admin level one in case the user forgets their BIOS/UEFI password?
Also - so Bitlocker/TPM doesn't have an option for a password requirement?
You mentioned that the BIOS/UEFI does not require the password if the system is rebooted. Does this mean only when Windows is properly rebooted? or that a password is only not required when the system isn't coming from a powered off state?
What about sleep/hibernation? Is a password required then to get past the BIOS/UEFI?Yes, we did add another level of complexity that was not necessary but something the boss wanted. The boot password is a password convention that the user and IT knows, but something that anybody outside of the company would not/should not know. It should be something fairly easy for them to remember because they have to use it everyday for them to use their computers anyways. No, its not their Windows password either.
The TPM stores the key for bitlocker to begin decryption in order to boot the system.
Lenovo systems detects when Windows is being properly rebooted and does not request the boot up password. We have not yet tested sleep/hibernation as that junk typically has never worked for me in Windows. I've not had a problem with hibernation/sleep in Qubes.
What's really funny is that you have the crazy mix of "require encryption" but "trust Lenovo." That makes no sense. Especially as the UEFI being malicious being one of the issues with Lenovo!
Don't get me wrong. I don't trust Lenovo. In fact, we're doing the slow migration away from Lenovo to Dell. That's just the practice that we have right now.

Sadly, this is more based upon the shit software companies write, and less on MS. The crap software makes hard calls to anticipated locations. this is not MS's fault.

I agree. Although MS doesn't handle it in a way that fixes that, either. They make it really easy to mess that up and even their own update process breaks - so MS's fault there.
UNIX had this solved in the 1970s, so even bad code doesn't have the issue.

I need an exact blow by blow how you would configure a Windows 10 system to have all but the admin profile saved to an encrypted D : drive, that would leave that D drive enrypted while updates are running, yet somehow decrypt the D drive when the user wants to be logged in. -

No clue what LUKS is, but assuming a single partition, how do you do remote updates to an encrypted drive? I'm assuming it can't boot without a user there to type in a password.

That's my whole goal here. Encrypt a single partition (D drive with users data on it) and leave C drive unencrypted so that the system can update automatically. User space doesn't get patched, so that it is encrypted shouldn't matter, or matter much (if something needs to be updated there you do it at a different time, the OS is way more important.)

We can encrypt home directories and still boot the machine. Why would it not be able to boot? The user data is on a separate drive. I'm lost as to why it wouldn't work.
