I want to add "UnLock Drive" to the Explorer right-click context menu with drive using bitlocker. How I do? Please help me! Thank !!!

Hi, That’s impossible, you cannot edit the items on Right Click context menu. Thank you for your understanding. Regards, Leo Huang Leo Huang TechNet Community Support

Yes, you can add right-click context menu commands. Its just a registry setting Here's some posts on how to add a "re-lock" command. You tweak the script and registry entries to make it an unlock command instead. http://social.technet.microsoft.com/Forums/en-US/w7itprosecurity/thread/41607938-7452-440d-8253-67fe8657bc0f What's odd is that Unlock drive command should already exist for you by default, but I too have seen it mysteriously disappear after some updates.
