I have a strange behavior, when I start-up the newest official Blender-release, my WebCam starts up. I cannot find any point. where to stop this. I guess, there's something "connected" to the start-up of Blender concerning "session-recording" for training-vid-production... I never had something like this.

Could please someon hlp me out of this?

Thanks Greetings Mike

    $\begingroup$ Reinstalling doesn't reset your user preferences, so that wouldn't do anything. Do you have any add-ons enabled? By default Blender doesn't do any video recording at all. Where exactly did you download Blender from? $\endgroup$ – dr. Sybren Nov 2 '17 at 12:41
  • $\begingroup$ From the official Blender site. And there are no add-ons enabled, that aqre pointing to recordings.... $\endgroup$ – Mike J. Gee Nov 2 '17 at 12:47

    $\begingroup$ OOhh my Goood!! I am sorry.. I found the issue. (I will write it also in the questions-section). I got meanwhile a new GraCard.. the Nvidia software installed a "Game-tracking"-feature. And obviously Blender was recognized as a "GAME!!" .. I'll give detailed data on the thread... $\endgroup$ – Mike J. Gee Nov 2 '17 at 13:11

I found the issue. It's really somewhat amusing:

I got and installed a new Graphics-Card on my system. (Geforce GTX 970) The set-up also installed NVIDIA GeForce Experience (V. and during install it set-up also "Game internal overlay", which basically opens the possibility for gamers to record videos of their game, the gamer himself, via WebCam and voices/sound.

The strange behavior is, that the Nvidia software recognizes Blender as a "Game" and switches on all the stuff. (I am not a gamer, so I never realized, that this is available at all)

After setting off this feature, everything turns back to normal.
