I have a dv7-4197cl which I updated to Windows 8.1 then I updated the drive for my Validity Sensor (WBF) VFS301 which said that I already had the most up-to-date driver. Then installed what I though was the latest HP Simplepass software.
When I open a web page that requires a login and password it asks if I want to set up and always click yes, and it just disappears. Help!
