These are probably hardware components that windows does not have a driver for. You may be able to right click on each missing device and select "properties" - something there may give you a clue about what they are. Is there any hardware or feature on the laptop or plugged in that is not working (eg bluetooth, network)?

Right click the driver, go to Properties, select compatibility tab then select to install in Windows 8 mode. You could also try the Win 8 Driver, might work.

Expand your Imaging device in Device manager, right click Webcam, and the generic driver for the camera should be in Properties.
