[Q] Weird driver problem

I have a weird problem getting fastboot to work on my Nexus 10.
Whenever I connect my Nexus 10 in fastboot mode to my pc it installs two drivers: Samsung Mobile USB Modem and SAMSUNG Mobile USB CDC Composite Device.
When I try to update the driver it won't allow me to pick a driver from Google and it does not work if I use the metod with a driver file and assigning the location.
I already tried a toolkit for installing the drivers but that did not work either..
