### Choose how BitLocker-protected operating system drives can be recovered
This policy setting is used to configure recovery methods for operating system drives.

|**Conflicts**|The use of recovery keys must be disallowed if the **Deny write access to removable drives not protected by BitLocker** policy setting is enabled. </br> </br>When using data recovery agents, the **Provide the unique identifiers for your organization** policy setting must be enabled.|
|**When enabled**|it can be controlled the methods that are available to users to recover data from BitLocker-protected operating system drives.|
|**When disabled or not configured**|The default recovery options are supported for BitLocker recovery. By default, a data recovery agent is allowed, the recovery options can be specified by the user (including the recovery password and recovery key), and recovery information isn't backed up to AD DS.|
#### Reference: Choose how BitLocker-protected operating system drives can be recovered
This policy setting is applied when BitLocker is turned on.
The **Allow data recovery agent** check box is used to specify whether a data recovery agent can be used with BitLocker-protected operating system drives. Before a data recovery agent can be used, it must be added from **Public Key Policies**, which is located in the Group Policy Management Console (GPMC) or in the Local Group Policy Editor.
For more information about adding data recovery agents, see [BitLocker basic deployment](bitlocker-basic-deployment.md).
In **Configure user storage of BitLocker recovery information**, select whether users are allowed, required, or not allowed to generate a 48-digit recovery password.
Select **Omit recovery options from the BitLocker setup wizard** to prevent users from specifying recovery options when they enable BitLocker on a drive. This policy setting means that which recovery option to use when BitLocker is enabled can't be specified. Instead, BitLocker recovery options for the drive are determined by the policy setting.
In **Save BitLocker recovery information to Active Directory Domain Services**, choose which BitLocker recovery information to store in Active Directory Domain Services (AD DS) for operating system drives. If **Store recovery password and key packages** is selected, the BitLocker recovery password and the key package are stored in AD DS. Storing the key package supports the recovery of data from a drive that is physically corrupted. If **Store recovery password only** is selected, only the recovery password is stored in AD DS.
Select the **Do not enable BitLocker until recovery information is stored in AD DS for operating system drives** check box if users need to be prevented from enabling BitLocker unless the computer is connected to the domain and the backup of BitLocker recovery information to AD DS succeeds.
> [!NOTE]
> If the **Do not enable BitLocker until recovery information is stored in AD DS for operating system drives** check box is selected, a recovery password is automatically generated.
### Choose how BitLocker-protected fixed drives can be recovered
This policy setting is used to configure recovery methods for fixed data drives.

In **Configure user storage of BitLocker recovery information**, select whether users can be allowed, required, or not allowed to generate a 48-digit recovery password or a 256-bit recovery key.
Select **Omit recovery options from the BitLocker setup wizard** to prevent users from specifying recovery options when they enable BitLocker on a drive. This policy setting means that which recovery option to use when BitLocker is enabled can't be specified. Instead, BitLocker recovery options for the drive are determined by the policy setting.
In **Save BitLocker recovery information to Active Directory Domain Services**, choose which BitLocker recovery information to store in AD DS for fixed data drives. If **Backup recovery password and key package** is selected, the BitLocker recovery password and the key package are stored in AD DS. Storing the key package supports recovering data from a drive that has been physically corrupted. To recover this data, the `Repair-bde.exe` command-line tool can be used. If **Backup recovery password only** is selected, only the recovery password is stored in AD DS.
For more information about the BitLocker repair tool, see [Repair-bde](/windows-server/administration/windows-commands/repair-bde).
Select the **Do not enable BitLocker until recovery information is stored in AD DS for fixed data drives** check box if users should be prevented from enabling BitLocker unless the computer is connected to the domain and the backup of BitLocker recovery information to AD DS succeeds.
> [!NOTE]
> If the **Do not enable BitLocker until recovery information is stored in AD DS for fixed data drives** check box is selected, a recovery password is automatically generated.
### Choose how BitLocker-protected removable drives can be recovered
This policy setting is used to configure recovery methods for removable data drives.

### Configure the pre-boot recovery message and URL
This policy setting is used to configure the entire recovery message and to replace the existing URL that is displayed on the pre-boot recovery screen when the operating system drive is locked.
