Windows 7 webcam access log?

Question

System administration

What are the possibilities for determining the fact of using a webcam built into a laptop running windows 7?
Was it ever used at all, and if so, when and by what software. Thanks in advance for your replies.

Answer 1

None.
Windows is a gaming system, everything is in it for the convenience of the user, the logs, if any, are very deep and often in a binary format.
