Use another device to open Microsoft’s BitLocker recovery-key page, sign in with the Microsoft account used when the PC was first configured, and match the listed key to the Recovery key ID shown on the locked PC.^1^
Retrieve the correct key
- On the BitLocker screen, write down the first eight digits of the Recovery key ID. This is an identifier, not the recovery key itself.
- On a phone or another computer, open: https://account.microsoft.com/devices/recoverykey
- Sign in with each Microsoft account that may have been used to set up the computer.
- Find the entry whose Key ID matches the ID displayed on the locked PC.
- Enter its corresponding 48-digit recovery key on the BitLocker screen.
On Windows 11 version 24H2, the recovery screen may display a hint identifying the associated Microsoft account.^1^
If the key is not in that account
Check these locations:
- Another person’s Microsoft account: If the retailer, a family member, or somebody else initially configured the PC or enabled BitLocker, the key may be saved to that person’s account.
- Work or school account: If one was ever connected, open https://aka.ms/aadrecoverykey, sign in, select Devices, expand the computer, and select View BitLocker Keys. Contact the organization’s IT department if you cannot view it.
- USB drive: Connect any USB drive on which the key may have been saved. If it contains a text file, read it on another computer.
- Printed copy: Check paperwork stored with the computer or other important documents.
If no key can be found
The encryption cannot be bypassed, and Microsoft Support cannot retrieve, provide, or recreate a lost recovery key. The remaining option is to reset or reinstall Windows using a Windows recovery option; this removes all files currently stored on the encrypted drive.^1^
If the computer was sold as new but someone at the store configured it before delivery, contact the retailer before resetting it; the key could be associated with the account used during that setup.
