My laptop has been locked down by Bitlocker

If your drive is encrypted with Bitlocker, the only place the Bitlocker Recovery key is automatically stored is on the associated Microsoft account on the link below, be sure to check any Microsoft account that may have been used on the PC and also any work or school account that may be linked to the PC.

Are you able to find the Bitlocker Recovery Key on any account that may have been used or linked to the laptop?

If not, do you have a safe backup of your files, or use a cloud service like OneDrive to sync your files online.

BitLocker encryption cannot be bypassed. Access to the locked drive requires a valid 48‑digit BitLocker recovery key.

BitLocker is designed so that if the recovery key cannot be provided, neither Microsoft support nor anyone else can unlock or decrypt the drive. If the recovery key that was previously shown in the Microsoft account no longer appears, and no other backup copy exists, the data on that drive cannot be recovered.

Actions to take:

1. Systematically re-check all possible locations for the recovery key as described in the BitLocker documentation:
   • Microsoft account (for personal devices)
   • Work or school account Devices page (if the device was ever managed by an organization) – from another device, go to the Devices page of the My Account portal and select View BitLocker Keys for that device
   • Any printed copy, USB backup, or file backup created when BitLocker was first enabled
2. If the key is found, enter the full 48‑digit key on the BitLocker recovery screen (hyphens are optional). If correct, Windows will start normally.
3. If the key cannot be found in any of these locations, the only remaining option is to remove/reinstall Windows on that drive, which will erase all data on the encrypted volume. This is by design and is the trade-off for the protection BitLocker provides.

If the device is managed by a work or school, the organization’s IT admin may be able to retrieve the key from their management system. For a purely personal device where no key can be located, data recovery is not possible.
