Is there a way to see a progress bar somewhere that shows how far the BitLocker control panel is in decrypting my drive?

I have no way of seeing how much more time it will take.

UPDATE:
I rewrote my original PowerShell script, so it's a "90% perfect" knockoff of the genuine BitLocker progress widget. You can specify the Drive letter on the command-line (by default it presumes you want to view drive C:).

Code: 
powershell -ep bypass -f BitLocker_Progress.ps1
powershell -ep bypass -f BitLocker_Progress.ps1 E:

It works for both BitLocker encryption and decryption passes. If you have multiple drives to monitor, run several opies of the script (each assigned to a different Drive letter).

Here's a terrible PowerShell script (which works for both encrypting and decrypting). It's terrible because I can't figure out why the PS progress window can't be dragged to another part of the screen. But otherwise, it works.

Well, that kept me amused occupied for a while: I was intrigued by the idea of a Powershell 'form'. I am an almost complete PS novice, and find its syntax on the command line arcane enough. In form mode it uses winforms, and its was tricky (for me) converting guidance aimed at programmers using stuff like C or C++ into its powershell equivalent. The powershell forum was helpful.

So I had some fun testing your script, determind to find out how to move the form when it is running. So far I have failed, but I now see the difference between a 'static' form, invoked with $form.show(), and a modal form, invoked with $form.ShowDialog(), where the user can click buttons and resize or move the form,

I tried to combine the two using $form.Add_Shown( function ) before ShowDialog - the result was that the form loads and runs the function (with its updating progress bar), but is static (no user interaction possible), and only when/if the function terminates does the modal behaviour start.

I believe there may be a possibility by calling up mouse activity functions, but I am done for now. Martin

Unless you have a huge amount of data and slow pc/drive, it does not usually take that long (less than 30 minutes say).

While I've written other WinForms scripts, never touched an animated progress bar before.

Gemini provided coding examples that used Show() and while loops. Obviously that's got a lot of drawbacks once you start testing. Later I found a better example of combining a WinForms timer and ShowDialog(). I've replaced my old script in post #3.

The script will fork itself into the background, so it's non-blocking from the command line. I realized someone might want to monitor progress on multiple drives, and it would be annoying to force the user to open another CMD or PS shell for each drive instance.

Updated script: it will take me a while to remove the bitlocker stuff, as I don't use that - but I see how it works, I think. Ta, Martin
