The installer copies ascript to the programs folder and creates the registry key (including sub-keys) inHKCR/Drive/shell/lock-bde. The latter basically adds the context menu entry if you right-click on an unlocked drive. For the lock function to work, the Windows programmanage-bde.exe needs to be called with elevated rights and it needs to be given the drive letter. Because it is not possible to achieve both things by calling the program from the registry, the(short) script is necessary, which strips the trailing backslash from the drive path (e.g. D:\ becomes D:) and requests the elevated rights.

The installer is localized, supporting German and English at the moment. Adding new languages is very easy. Just download/copy the fileen.nsh, rename it, open it in a text editor, translate the strings andsend the file to me.

Download the latest installer and execute it.

Go to your download folder and execute thelatest installer. Because it creates the drive context menu via registry keys inHKCR, the installation requires elevated permissions, so it cannot be installed as a user.

Go to the WindowsControl Panel > Programs > Uninstall a program. There you will find it asBitlocker Drive Locker - Explorer Context Menu Entry (or its localized string). SelectUninstall and all created registry keys and folders will be removed.

Thecomplete source is assembled from text files and is human readable. It basically consists of themain NSIS installer script file including thetranslations, some documentation and thewrapper script formanage-bde.exe.

The installer can be created by downloading and installing the latestNullsoft Scriptable Install System (NSIS) and using it to compilebdelock.nsi.

Even without knowing the detailed NSIS or VBscript syntax, you should be able to understand the source files.
