How to Lock an Unlocked BitLocker Drive
Currently, if you unlock a drive that has been locked with Bitlocker, you will need to either restart explorer.exe or reboot your PC. Neither of these appeal to me so I found a way of adding "Lock" to the context menu menu which, when clicked, re-locks the drive.
WarningInvolves editing the registry. Proceed with care if new to registry editing and back up your registry before hand
Here's How:
1. Open Notepad and paste this below in it.Now, when you right click the drive, you'll see "Lock". Clicking this will re-lock your drive.
NOTE: Replace x: with the drive letter you wish to apply it to.
manage-bde -lock x: -ForceDismount2. Save the file as lock.bat to your desktop, then move it into your C:\Windows folder.
3. Open regedit and navigate to: HKEY_CLASSES_ROOT\Drive\shell
4. In the left pane of regedit, right click on shell, click on New and Key, type runas, and press enter.
NOTE: This key may already exist with the value of TakeOwnership. If it does, name the new key runas(2) instead.
5. In the right pane of runas or runas(2), double click on (default) to modify, type in Lock and click on OK.
6. In the left pane of regedit, right click on runas or runas(2), click on New and Key, type command and press enter.
7. In the right pane of command, double click on (default) to modify, type in C:\Windows\lock.bat and click on OK.
8. In the right pane of runas or runas(2), click on a empty space and click on New and String Value, type in AppliesTo and press enter.
9. Double click on AppliesTo to modify, type in X: and click on OK.
NOTE: Replace X: with the same drive location as you did in step 1.
10. Close regedit.
Micrsoft needs to fix this IMO but this is an excellent work around. Props to "Jonathon" for coming up with the original method.

Set known file extensions to be displayed, then double check to make sure that the lock.bat file name is name correctly and not something like lock.bat.txt instead.
Also make sure that the drive letter used in the command is correct for the drive.

ok so this is the message I get ..
"Error recovering disk H: The recovery key you tipped is not correct.Type it again."
note that I already removed my password, started decrypting my external hard drive (took about 24 hours) and then at the end of unlocking, I guess because I wasn't there, I got message there is an error on drive please run disk check and there was some command but I clicked to close and did not wrote it down..
forgot to upload one more pic.. I am typing that number.. still got the same result
It put's dashes automatically..even if I try to put them nothing happens..
sry about that.. yeah I notice that also but he corrected me and send that one part was wrong.. the part where I put 9 instead of 0
I have a question.. this option that tw33k put here is for locking. so if I follow tutorial in my locked drive I should have option Unlock?Last edited by ItachiSharingan; 04 Aug 2011 at 16:36. Reason: merged

Be sure that you are typing in the real long number at the very bottom of that .txt file, and not the ID numbers above it. I can't remember if the dashes have to be included or not, so try both ways.
653939-.............
EDIT for your addition:
You have a typo in that last number you typed.
