Windows 10: Some Microsoft account, which I have no idea, locked my hard driver

BitLocker suddenly locked my laptop/hard drive, which, I think, some Microsoft account activated. I have no idea which account performed the task, so I have no access to the BitLocker key. There is no way to reach Microsoft for help. What can I do?

Locked Out of Admin Account

Hello Linda,



Thank you for writing to Microsoft Community Forums.

1. Are you using a Microsoft account or a local account?
   
2. Which version of Windows 10 you are using currently?
   
3. Is the other user account an admin account?
   

I suggest you to try using the on screen keyboard at the login page and check if you are able to login to the PC.

1. At the login screen click on the
   ease of access icon at the bottom right hand corner.
   
2. Click on the on screen keyboard to open it.
   
3. Type the password and try to login.
   

If you are using a Microsoft account, I suggest you to refer the article on

how to reset your Microsoft account password.



However, if you are using a local account, then I suggest you to refer the article on

reset your Windows 10 local account password.



Note: While performing these steps, there might be a risk of data loss. You may take a backup of the data before performing the steps.



Hope it helps.
