BitLocker is officially only available for Windows 10/11 Pro. However, ... the subtle difference to Windows Pro is that the Home version lacks the addition “manage” and BitLocker does not start.

BitLocker is available in Windows 11/10 Pro, Windows 11/10 Enterprise, and Education editions. It is not available on Windows 11/10 Home editions. We all use USB Flash drives or thumb drives.

To activate them or confirm that they’re active, open the Windows Security app from your Start menu. Click “Device security” ...

You can add or remove the Manage BitLocker context menu from all unlocked drives encrypted by BitLocker for all users in Windows 10. The procedure involved is the same as mentioned above.

Open the Windows search bar, type "BitLocker," click on Manage BitLocker and open it. Find your removable drive under Removable data drives – BitLocker To Go and select it.

BitLocker is available to anyone who has a machine running Windows Vista or 7 Ultimate, Windows Vista or 7 Enterprise, Windows 8.1 Pro, Windows 8.1 Enterprise, or Windows 10 Pro.
