BitLocker is a full disk encryption feature built into certain versions of the Windows operating system. It helps protect your data by encrypting the entire drive or specific volume, making it unreadable without correct authentications, such as a password or BitLocker recovery key. This BitLocker encryption helps safeguard important data especially when your computer is lost, stolen, or accessed by unauthorized users.

Most BitLocker users would rather unlock the BitLocker encrypted drive than turn off BitLocker to access and modify its data. An unlocked BitLocker drive means the drive can be used as normal but the data is still protected by encryption.

However, by default, there is no "Lock drive" GUI options or tools to lock the BitLocker encrypted drive in Windows 10. To lock it, you have to restart the Windows 10. Is there any way to lock BitLocker encrypted drive without restarting in Windows 10? Some BitLocker users wonder and quest for possible solutions.
