How can I quickly check in Windows 11 whether my system drive is encrypted?
Open Settings > Privacy & security > Device encryption; if the toggle is On, your system drive is encrypted, and if that page does not exist your hardware never qualified. You can also check Settings > System > Storage > Disks & volumes, select the volume and open Properties to see a BitLocker note, or run Terminal as administrator and execute manage-bde -status C: to report conversion status, encryption method, and whether protection is on.
