I have bought a new keyboard (Logitech k400), and it's trackpad has two finger scroll which works in the 'standard' windows direction (swipe up to scroll up the page). However my laptop's built in touchpad (synaptics driver) has 'inverted' scrolling (swipe up to go down, like on OSX). How can I invert the scrolling? Will I need to install a new/customised driver?

If Windows 7 interprets the trackpad's gesture-scrolling as anything similar to a standard scroll-wheel, you may well find what you're looking for in Super User question #310681. There are a few different answers that you may want to give a run.

Go to Start Menu>'Change mouse settings'>ELAN/Synaptics tab>Options...

There you are!

It’s a Logitech wireless keyboard/touchpad combo, nothing Synaptics here. – Daniel B Jul 31 '15 at 8:34

This tool will set or remove the 'flipflopwheel' registry setting in windows for all mouse devices.

Run this exe... flipflop-windows-wheel
It works like a charm!
