Relock 1.0.1, authored by Manfred Mueller, is a lightweight Windows utility designed to re-lock BitLocker-encrypted volumes on demand and instantly display the corresponding 48-digit recovery key, giving administrators and security-conscious users a quick way to restore the protected state of a drive without rebooting or navigating multiple Control Panel screens. Because BitLocker normally keeps a volume unlocked until the system is powered off or the key is manually suspended, Relock fills the gap by letting anyone who possesses administrator rights force the drive back into encrypted, locked status the moment sensitive work is finished; the exposed recovery key can then be archived in a password manager, printed for offline storage, or transmitted to a help-desk ticket so that authorized personnel can regain access later. Typical use cases include shared workstations in medical or financial offices where customer data must be sealed between sessions, IT labs that need to demonstrate BitLocker behavior during training, and remote laptops whose owners want to ensure that confidential projects are cryptographically inaccessible if the device is left unattended. The program supports both fixed and removable drives protected by a password, TPM, or USB key, and its command-line interface can be scripted through Group Policy, SCCM, or PowerShell for mass deployment across domains. Relock is distributed as freeware on get.nero.com, with downloads supplied through trusted Windows package sources such as winget, always serving the latest version and enabling batch installation of multiple applications.
