Built in camera won't work after update but it works on skype and the like?

I recently reformated and updated my lenovo n585 to windows 8.1 then intalled the needed drivers. At devce manager, it said that the camera is installed and working properly. And it does work but only in skype facebook and anything that asks for a cam. But it won't work if i just go to windows>camera. It says i need to connect camera. What shoud i do?
