Windows 7/8/8.1 Drivers For The ALPS Touchpads In The Dell Latitude 7x90

What does the "x" in "Latitude 7x90" mean?

There are 3 modules of the Dell Latitude series that i know share the same touchpad hardware, instead of writing 7290, 7390 and 7490 i decided to write 7x90 to save space and save me time

Why did i do this?

For people who installed a windows version Dell says are "unsupported" they'll soon quickly realise the touchpad wont work at all in windows 7 or will work in windows 8.1 albiet very buggy if lucky

I wanted to help such people out

What would i lose over the actual windows precision drivers if they were on windows 7/8/8.1?

Nothing really, at most probably like that cool zoom feature if you get what i mean

ON WINDOWS 7 YOU WILL LOSE MULTITOUCH DRAGGING, this is fine tho since bringing the trackpad to edge while dragging will make it still drag albeit it slowly

Prerequisites

Make sure "Disable Driver Signature Enforcement" is enabled

Make sure you have the "Intel Serial IO" driver installed

Tutorial

Download the repo, find the folder suitable to your windows version and then run "DPInst.exe"

Allow any unsigned driver installs

Press yes to any UAC Prompts

Finished :D
