Windows 10: Bitlocker key, no Microsoft account and no idea why the bitlocker activated.

My son's Asus notebook with Windows 10 Home is looking for a bitlocker key. It is his own laptop and he does not have a Microsoft account to recover a key. We have no idea why the bitlocker activated as he has not update or added any new application. Looking for help please.

Bitlocker key can not be found in the microsoft account

After a regular update of Windows my Notebook asked me for the Bitlocker Key although I never activated this. The device is listed in my account but in the list of keys it's not.

Simply doing a reset is definitely not an option, the data is needed.

Every single suggestion for how to find the key is absolutely useless so far.

Bitlocker Keys

According to the above article:

If your device is a modern device that meets certain requirements to automatically enable device encryption your BitLocker recovery key is automatically saved to your Microsoft account before protection is activated.

If in your Microsoft account: Sign in to your Microsoft account on another device to find your recovery key. If you have a modern device that supports automatic device encryption, the recovery key will most likely be in your Microsoft account. For more, see Device encryption in Windows.

Other common ways for BitLocker to start protecting your device:

• An owner or administrator of your device activated BitLocker protection (also called device encryption on some devices) through the Settings app or Control Panel: In this case the user activating BitLocker either selected where to save the key or (in the case of device encryption) it was automatically saved to their Microsoft account.
  
• A work or school organization that is managing your device (currently or in the past) activated BitLocker protection on your device: In this case the organization may have your BitLocker recovery key.
  
• 
  BitLocker is always activated by or on behalf of a user with full administrative access to your device, whether this is you, another user, or an organization managing your device. The BitLocker setup process requires the creation of a recovery key at the time of activation.

If you can't find the key then try to boot into Windows (if at all possible) and then decrypt your machine by turning off bitlocker.
