As the Title stated, I used the windows 7 Pro driver for my brother's HP Probook 4520s that came with windows 7 Pro but upgraded to Windows 8 and it was working for a few seconds then the driver failed.. I made sure I used the correct driver and such.. So I'm thinking that the webcam driver for windows 8 isn't ready yet. Ugh.. So looks like my plan to use Skype for windows 8 on my brother's HP Probook will have to wait until they bring out the driver for Windows 8 Pro. I wonder when they'll do that.. Also checked on HP site to see if there's ANY drivers for windows 8 Pro for this laptop.. nothing yet..
