I have installed updates from 12th january, including KB4535680.
After installation, BitLocker ask for a recovery key on boot up.
Probably because the updates added dbx modules to the UEFI.
This issue is also described here:
The problem at hand is, that i never knew that i`ve turned on BitLocker. Neither i know the recovery key. It is also not in my microsoft account.
I had this problem with BitLocker two times before and used this workaround for my Dell Inspiron 5580:
Unfortunately this does not work this time...
Is there a way to fix this??
- uninstalling the update although i cannot unlock the bitlockered system drive?
- resetting the UEFI dbx changes? (reflashed the firmware, but without success)
