A BitLocker recovery screen does not automatically mean your files are gone. It means Windows needs the 48-digit recovery key that matches the encrypted drive.

Do not choose Reset this PC as a shortcut. If you cannot unlock the drive, a reset can remove the files you are trying to protect.

1. Photograph only the key ID

Write down the first eight digits of the recovery key ID shown on screen. The ID is not the recovery key; it helps you match the correct key when an account contains several.

2. Check the likely account

  1. From another device, visit aka.ms/myrecoverykey and sign in with the Microsoft account used on the locked PC.
  2. If the PC ever used a work or school account, check that organization's device portal or contact its IT administrator.
  3. Look for a printed copy, a text file saved to a USB drive, or documentation from the person who set up the PC.

3. Match before entering

Compare the key ID on the recovery screen with the ID beside the stored recovery key. Do not guess between multiple keys.

4. Protect the key

Treat a recovery key like a password. Do not post it in a forum, send it in a screenshot, or include it in a support message. RestorePath Lab will never ask you to send it.

5. If no key exists

Microsoft cannot recreate a missing BitLocker key. Before accepting data loss, check every Microsoft account and any previous owner or organization that managed the device.
