my pc came with an inbuilt webcam but after it was formatted by a technician the driver disappeared. Moreover, being a novice I cannot even locate the webcam position to determine its make\model, etc. Help me please
Are you sure that you need an additional driver for the web cam? Most don’t try checking it out with one of the web sites that tests your web cam (flash required).
If you do require a driver and Microsoft update does not have one then the only place you will get one is from the manufacture of your laptop web site.
