To decrypt BitLocker, you can follow the steps below:
1. Open the "Control Panel" in the Windows operating system, and click "Control Panel" can perform various system settings and management. Therefore, we need to open the control panel first.
2. Select the "System and Security" option. In the control panel page, find the "System and Security" option and click to enter.
3. Select the "BitLocker Drive Encryption" option. On the "System and Security" page, find the "BitLocker Drive Encryption" option and click it.
4. Find the drive that needs to be decrypted. On the "BitLocker Drive Encryption" page, you will see a list of all encrypted drives on the current computer. Find the drive that needs to be unencrypted and click the "Unprotect" button next to it.
5. Verify, decrypt, and authenticate. After clicking the "Unprotect" button, the system will prompt you to authenticate. This is to confirm that the decryption request is legitimate. Administrator authentication is usually required to ensure you have permission to de-encrypt. Enter the correct password or verification information and click the "OK" button.
6. Wait for decryption to complete. After the authentication is passed, the system will start to decrypt the drive. This process may take some time, depending on the size of the drive and the performance of your computer. Please ensure that your computer does not lose power or shut down during this period. When decryption is complete, you will be able to access the data on the drive.
In addition to the above methods, BitLocker encryption can also be decrypted in the following ways:
1. Use password to decrypt: If a password is set during encryption, you need to enter the correct password to decrypt when turning on the computer. .
2. Decrypt using the recovery key: The recovery key is an important backup key generated when BitLocker is enabled. If you forget your password but have a recovery key, you can decrypt the drive by selecting the "Enter recovery key" option when turning on the computer and entering the correct recovery key.
3. Use Active Directory decryption: If the computer is connected to an Active Directory domain, and the administrator has set up BitLocker's Active Directory recovery information store. You can contact your administrator to obtain a recovery key to decrypt the drive.
4. Use BitLocker to restore: If the computer supports TPM and has saved the TPM information to a file, you can use the restore to decrypt BitLocker. Select the "Restore TPM" option when booting, and then use the saved TPM information to decrypt the drive.
It should be noted that deactivating BitLocker encryption requires certain permissions and authentication information, so you need to ensure that you have the correct password or recovery key and other authentication information before operating. At the same time, for operations involving sensitive data, it is recommended to back up the data before the operation and ensure the security of the operation.
