Hi @seadas

Welcome back to the HP Support forum.

I am afraid Bitlocker doesn't appear activated just like that , out of nowhere. It was activated before the update of Windows appeared.

Have you tried removing *all* of the PC peripherals and stuff connected to the computer, then pressing and holding the power-on button for 5-10 seconds and then starting the PC ? Does it still ask you for Bitlocker key ?

BitLocker is a Microsoft software designed to protect your PC against offline attacks, unauthorized access typically if your PC gets stolen. BitLocker is full disk encryption software. More info:

BitLocker was activated by someone and during the PC activation time it prompts the user to save/store the key in a safe place.

** If this is a company owned asset/tablet, you should turn to your company's IT support guys and they should be able to provide you with the recovery key

** I did read this computer doesn't have Microsoft account but IF this is your own personal device, and if you are not aware of Bitlocker key, most probably you use a slightly different BitLocker version for certain PCs and tablets known as Device encryption. Probably your key is stored in Microsoft OneDrive with your Microsoft account here :

Please, note that it is very important for security reasons that you keep the encryption key (Bitlocker key) in a secure place so that only you know it.

Try these and let me know if you manage to find the key
