BitLocker is a disk encryption tool integrated into Windows 11/10, but it is only available in the Pro and Enterprise editions. Windows Home users also have disk encryption needs, so the absence of BitLocker is a significant limitation for them. Is there still a way to encrypt the Windows partition (C: drive) with BitLocker on Windows 11/10 Home? The answer is to use Hasleo BitLocker Anywhere, and you can find the detailed steps below.

How to Encrypt Windows Partition (C: drive) With BitLocker in Windows 11/10 Home?

Step 1. Download and install Hasleo BitLocker Anywhere.

Step 3. In this step, you are asked to choose how to unlock the Windows drive at startup. You can choose to enter a password or insert a USB flash drive each time you start your PC.

If you choose to enter a password at startup, you are required to specify a password for encrypting the drive, enter the password and click "Next". You should choose a password having a combination of upper and lower case letters, numbers, spaces, and special symbols.

  • Encrypt used disk space only: Encrypts only the space currently used by the drive's file system. Unused space remains unencrypted. This option saves time during the encryption process. After you encrypt a drive with this option, any files you add to the drive are automatically encrypted.
  • Compatible mode: If the drive you plan to encrypt needs to be used on Windows operating systems prior to Windows 10 Version 1511, choose compatible mode. Windows 10 Version 1511 introduced a new disk encryption mode (XTS-AES) that is not compatible with older versions of Windows. The compatible mode (AES-CBC) is fully compatible with older versions of Windows.
  • Use 256-bit encryption: BitLocker supports 128-bit and 256-bit encryption strengths. 256-bit encryption is more secure but consumes more CPU resources. Choose the encryption strength based on your needs. Select this checkbox if you want to use 256-bit encryption strength.

 

Step 4. After clicking "Next", you are asked how you want to backup the BitLocker recovery key. You can save the recovery key to a file or print a copy of it, then click "Next" to move on. Please note that anyone can use the recovery key to gain access to the drive, even if they do not have the startup key or password created in the previous step, so please do not disclose it to others.
