Welcome to Windows Seven Forums.

You need to check with the HP support site for Windows 7 drivers and download and install any that are needed.

You may need a different region as I'm not sure where you're from.

Was your webcam or fingerprint reader ever working in Windows 7? you may need to reinstall the drivers. just below your screen there should be a model number, search HP's website for the drivers for this device.
