Which program or process is using ManyCam?

[IMAyNeed]

I closed all the video windows, and ManyCam is still going on broadcasting. I changed the camera source to a different camera and it was still broadcasting (Usually when I press the close button, it stops broadcasting unless there is a video window open).
How can I find out which program or process is using it?

A clean boot is the way to start

Then I won't be able to see which process was using it. If there is a backdoor in one of my programs or firewall settings, or anywhere on my computer, I would like to see it.

No,
You do the clean boot and if the the camera stops, you put the programs back slowly, until the camera starts.
