Windows 11
I am troubleshooting a failure to upgrade to 22449.1000 and when I installed MiniTool Partition Wizard Free to adjust partition sizes I found that my C: drive and D: drive were both bitlocker encrypted! I never turned on bitlocker nor encrypted drives before. I know the drives were not encrypted under Windows 10. Somewhere in the process of upgrading Windows 10 to 11, or upgrading Windows 11 through the various builds, Microsoft encrypted my drives without notifying me. If there was an issue and I needed to recover files from the drive, this could have presented a huge issue! I really don't like all the "enhanced security" that Microsoft is enabling without notifying the user first when they upgrade from Windows 10 to 11.

So, I wonder, now that I am decrypting the drives and turning bitlocker off, if I do get a successful upgrade to 22449.100 if it will enable bitlocker and encrypt again without giving me a choice?

Might want to read this...

Mandatory Microsoft accounts for Windows 11 Home might be a good thing


One of the features where the MSA will matter is with BitLocker, which encrypts the contents of the storage drive. BitLocker has been available since Windows 8. On Windows 10, it’s been on by default on newer machines that support a feature called Modern Standby (basically making PCs wake up as fast as your phone). If you haven’t noticed BitLocker on your new computer it may be because, well, you skipped creating a Microsoft account and used a local account. If you did that, BitLocker is not turned on.


BitLocker will be enabled by default on all Windows 11 PCs. Once the drive is encrypted with BitLocker, Windows asks where you’d like to back up the encryption key. The key reduces the odds of the data being tampered with, should your laptop get stolen or lost. It’s stored inside of the firmware TPM in the CPU, or in a discrete TPM 2.0 module, where it will be called upon to unseal the drive during the login process.

Here is Windows 11 Pro, currently 22000.176 Beta channel. I never switched on BitLocker and never used it before (all important files are stored on removable drives). But if it is on one way or another, it shouldn't be a problem to switch it back off in Control Panel, look for BitLocker Drive Encryption.

Bit locker also turned itself on on my pc during upgrade to Win 11, it was no problem I just turned it off again but I did not enable it.

That is not true. I was never asked where I'd like to back up the encryption key. I was not notified in any manner that Windows 11 had encrypted my drives - and that is a serious issue to me considering how hard it can be to get into an encrypted drive. One example, my daughter's laptop failed to boot after an upgrade to Windows 10. I was able to remove the hard, connect it to my desktop, and use dism to revert pending changes, the replace the drive back into her laptop and solved the problem. If the drive was bitlocker encrypted - plus now TPM required - it probably would have been next to impossible for me to do that.

I just noticed that. I went to Privacy and Security, and Device Encryption wasn't there. :)
I had been under the impression, that Home didn't have BitLocker on Win 10, but on Win 11 it did. Apparently, that's not the case.


But from that article, I wonder IF being tied to a Microsoft account, is what's turning on BitLocker?

I used WinAeroTweaker's instructions to remove the Turn on BitLocker entry in Explorer to avoid accidents! Being under Pin to Quick Access on 10 it struck me as being a possible accidental click target. Can still turn it on from Control Panel if required.

Probably a long shot but If you were say on this PC and inadvertently clicked it, that could possibly cause all drives to be affected, given that some windows do not appear on top in Win11, could be bitlocker window or whatever happens after turning it on wasn't seen as it was behind something else?

BitLocker will be enabled by default on all Windows 11 PCs. Once the drive is encrypted with BitLocker, Windows asks where you’d like to back up the encryption key.

That is not true. I was never asked where I'd like to back up the encryption key. I was not notified in any manner that Windows 11 had encrypted my drives - and that is a serious issue to me considering how hard it can be to get into an encrypted drive. One example, my daughter's laptop failed to boot after an upgrade to Windows 10. I was able to remove the hard, connect it to my desktop, and use dism to revert pending changes, the replace the drive back into her laptop and solved the problem. If the drive was bitlocker encrypted - plus now TPM required - it probably would have been next to impossible for me to do that.
Same here, It was only by chance when I was looking through settings etc. in Win 11 I noticed it. I was never ask either as far as I can remember.

Upgrading from 22000 to 22449 manually using the ISO did NOT re-encrypt the drives. So maybe it only happens on the initial upgrade from Windows 10 to Windows 11.

Interesting,.,, how did you verify what the status of the encryption was? I want to check it out.

I am not on any W11 version, but I have used BitLocker since W8, i.e. since BitLocker became available to general population. I like it very, very much, but I also fear how easy it is to lock yourself out (never happened to me, thank goodness)

My suggestions FWIW

Make 3 backups on 3 different external media. These external media can also be BitLocker encrypted with auto-unlock if you connect them to your BitLocker encrypted machine (so that you don't have to unlock them manually)

1 backup can always be connected to your machine, it's nice to have incremental backups every hour, for example. But only connect the 2 other backup media for backup purposes, and never ever connect the 2 other backups at the same time to your machine. If one backup is connected to your machine for backup purposes, make sure the other backup is disconnected from your machine. That way at least 1 backup is always safe from whatever happens on your live system, BitLocker-wise and otherwise.

There are 2 different types of BitLocker keys, unlock and recovery. Your machine and each backup have these 2 types of BitLocker keys. Without the right keys, the data on your machine and backups is safe even if you lose your machine and backups. But the very same thing also means that you yourself can lose all your data! That's the two sides of the same coin that's really fearsome > make 3 copies of all these BitLocker keys on 3 different media.

I don't pretend to have established a best practice, but it has kept me out of trouble since W8. Vice versa, if for some reason or another, you can't apply the above precautions, I strongly recommend to avoid BitLocker. And if you can't avoid BitLocker without being able to apply the above precautions, don't store any important data on that machine.

Disclaimer: Use the above at your own risk.

Edit: The above posts looks like an MS error that they reversed. Otherwise, with keys that are 20+ characters long, not even law enforcement can get at the data.

So, I wonder, now that I am decrypting the drives and turning bitlocker off, if I do get a successful upgrade to 22449.100 if it will enable bitlocker and encrypt again without giving me a choice?
It's possible it will enable it again, if it's the new default. By chance it might respect your choice after dealing with the decryption process. My experience noted below.

Be careful if you never used Bitlocker and encrypted disk and where you suddenly see it as active by its own.
I'm not saying the tech is wrong but you might get surprised by some nasty errors or warnings you've never seen or expected. At least for me it was something new to deal with.

I know how frustrating it is. I never used it myself either; I have encountered this on Windows 10 already. And it gets worse if you use imaging tools like Macrium Reflect since those will brake the encryption showing an open lock icon (possible with a warning when you start a backup).

So I never enabled anything. Seems that Bitlocker was running already on disk (while the options in Control Panel said it didn't, weird). This is on a NUC 8th gen which has TPM enabled. It happened after I switched to a WD M.2 SSD with OPAL encryption. Since then, poof, it was on. After backing up with Macrium Reflect, it was disabled during image creation but it reverted Bitlocker back on even after I replaced the drive with a non OPAL one, I was on a Samsung EVO 860.

To make matters worse, I could not decrypt the drive on same machine (NUC) and I always got a I/O error, on a new SSD.
What solved it: put the drive in a SATA bay in another PC, a desktop tower (also on Windows 10) where it decrypted fine, after some time though.
Then on the NUC I made sure Bitlocker was disabled in Control Panel, though after decryption the drive didn't get encrypted again on its own.

Of my 5 computers, all with "PRO" versions of Windows 10, and with Windows 11 .184 or DEV builds, NONE are bitlocker encrypted. So I am confused as to why some are encrypted and some are not.

It's the Dev version that's the issue... but something we need to look out for in updates... doesn't This PC have the padlock thingy when a drive is Bitted?
