When Installing Synaptic Touchpad Driver Nothing Happens!!

Hey guys..

I have got a new laptop, Dell Inspiron 15-5888 5000 series. It's all great but there's only 1 problem..

The touchpad, it works correctly, but it hasn't any features, like scrolling, zooming, etc.

When I go to Dell -> Support, entering my Service-Tag, go to Drivers and downloads, Keyboard, mouse and other input devices, I can't find the Synaptic touchpad driver listed, I only find something called Unifying or something like that.. I tried to download a synaptic driver that's compatible with Dell Inspiron 5558, downloaded and installed it, but nothings happened after that, I looked it up on google, and found that there isn't a synaptic driver for my type of dell, but there's something called Alps, I don't really remember what was it called, anyway, I downloaded it, but also nothing happened.. Btw I have windows 10, and in my previous laptop, I used to get the Synaptic touchpad driver outta windows update, now there isn't any driver for synaptic in the drivers that listed in windows update.. any help guys?
