While I was working I couldn’t find any built-in all in one place to do things in BitLocker rather than a panel in
Control Panel\All Control Panel Items\BitLocker Drive Encryption
By little bit of googling I saw there is a CLI to do stuff which is located in %windir%/system32/manage-bde.exe
I created a very simple GUI to do functions using manage-bde. This is currently in beta version and supports re-lock, unlock, decrypt and upgrade BitLocker drives. In upcoming releases I hope to add several more features like encrypt, backup and continue as a all-in-one place to work with windows BitLocker.
