Hi guys
I hope I will be able to explain the serious issue that happened to me recently..
I m providing tech support so a few days ago received a laptop with forgotten windows pin/pass issue then I booted the device with my winpe utility USB (changing Bios setting as disable Secure boot) right after I ve seen a message saying that C drive is locked and cannot be accessed (with locker). First I asked my customer if that set any encryption and the answer was No they didn't even know what BitLocker was. Right now even I change bios secure boot enable first thing comes to enter 48 digit code mentioning BitLocker which was never ever set... and I 've been looking many places on youtube, forums, articles however couldn't find anything clear.

I simply can reformat the laptop and install all again but since my customer has only one important doc which hasn't been backed up somewhere else I m looking some help or advice if anyone has same issue..
I m trying understand how windows 10 can encrypt someone without warning.

best regards
 
What is the exact message you see? Word for word?

If it is BitLocker, as far as I know, Bitlocker does not set itself.

Does anybody else have access/use to the computer? Has your client ever let anyone remote in to "fix" issues?
 
Hello

I ve attached the image how it looks like..

Can you get to a command prompt?

If so, try manage-bde -status and hit Enter to see which drives are encrypted.

Then in the same prompt type Disable-Bitlocker -MountPoint "C:" and hit Enter (or whatever drive letter that is encrypted you want to decrypt)

If this doesn't work, I'm afraid you'll need to do a clean install.
 
Unfortunately if the drive is bitlocker encrypted, there's no way to get the data off without the recovery key.

Windows will now enable bitlocker by default on many machines, although normally you won't notice it as it's transparent. Unfortunately changing secure boot settings can trigger bitlocker to require a recovery key as you've discovered.

That said, bitlocker should be smart enough to store the recovery key (or prompt the user to save it) before encrypting the drive.

If the computer was originally set up with a Microsoft account instead of a local account, the recovery keys are normally linked to that account. See Finding your BitLocker recovery key in Windows
