Fix 4. Run AOMEI Partition Assistant to encrypt files

Certain Windows versions, such as Windows 11 Home, have the "Encrypt contents to secure data" option greyed out because they don't support content encryption. However, AOMEI Partition Assistant Professional offers you the BitLocker function as an alternative for encryption.

Once you successfully store the key, a TXT file named "Bitlocker Recovery Key + 45-bit Key" will be created containing the recovery key. Keep this file safe.

Step 5. The encryption process may take some time. Don't close the program, remove the drive, or shut down the computer until encryption is complete. Once done, click "Completed". Your drive is now BitLocker encrypted.
