USB Drivers on Windows 10

Greetings!

I have been playing around with my Xperia Z2 for a couple of days now, and I cannot seem to get the last remaining drivers installed, that is required for me to unlock boot loader.

I have tried the ways described on Androids "unlockbootloader" website, without succes.

Then I started googling around, and found a driver tool in another thread (http://forum.xda-developers.com/show....php?t=2635830) and when I run the program, and select the "Fastboot Drivers", it fails the installation.

When I try to install the driver manually from "Device Manager", where you select the driver for "S1Boot Fastboot" --> Browse my computer for driver software --> ~\Local\Android\sdk\extras\google\usb_driver

So what could I have done wrong? Or could it be that the drivers just aren't compatible with Windows 10 yet?

Any help or guidance appreciated!
