6430u, Win10-Pro & Fingerprint reader and trackpad scrolling

I tried updating my 6430u from Win7Pro to Win10Pro and while it went well except for a couple of glitches. The fingerprint reader would not initialize in Win10Pro when it works just fine in Win7Pro and the Trackpad would not scroll by moving my finger down the right side of the trackpad in Win10Pro while it works fine in Win7Pro.

Anyone have solutions to these problems? Point me to a post or article on how to get these to work? I did a Dell auto-detection for drivers after the upgrade of the OS and nothing showed as needing updating.

thanks for any help.
