How to Lock BitLocker Encrypted Drive in Windows

Both Windows 10 and Windows 11 have a security feature called BitLocker. BitLocker is a file encryption tool that can password protect your Hard disk drives and SSD. Windows 11 also has an addon called BitLocker To Go, which covers the removable drives.

While BitLocker is a great security feature, once you unlock a locked drive, you can’t close it again without a restart. Restarting Windows to lock a protected drive isn’t the best option, especially if you often leave your PC unattended.

BitLocker Manager also doesn’t offer you an option to lock an unlocked drive. Hence, you need to rely on Command Prompt or PowerShell to instantly lock a BitLocker encrypted drive without restarting your Windows 10/11 computer.
