Windows 7: Lock Drive with Bitlocker?

just wondering, when a drive has been unlocked with bitlocker, is there a way to lock it again without restarting the PC?

How to re-lock a Bitlocker drive

So you've turned on Bitlocker encryption for a drive. You've unlocked it and done your work, but how do you re-lock it? Here's how to add an entry to the right-click context menu to re-lock the drive.

1. Open up Notepad and type in the following, replacing 'E:' with the drive letter of your Bitlocker drive:

manage-bde -lock E: forcedismount

2. Save the file as lock.bat somewhere accessible, such as C:\Windows or C:\Program Files\

3. Open up Registry Editor. Navigate to the following Key:

HKEY_CLASSES_ROOT\Drive\shell

4. Create a new key named runas with the default value set to Lock.
5. Now right-click on runas in the left window pane and create a new key called command.

6. Set the value of the Default Entry to c:\windows\lock.bat or whatever locaiton you chose at step 2.

7. Navigate back to the runas key and create a new String Value called AppliesTo. Set the value to E: or whichever drive you have encrypted.

8. Goto Windows Explorer and test your new right-click context menu entry!

Use caution when in Registry!

This feature is implemented in Vista, so I guess it will be in Windows 7 too.
