Look, I really don`t know what is going on because I uninstalled the Microsoft's drive and the software, then I restarted my computer and after that and automatically, the driver installed "itself" again. So, I decided to disconnect from internet and repeat the procedure again. After restarting my computer, I installed the Catalyst and restarted again the computer. Finally, when it was up and running again (the computer), no new driver was installed and when I reconnected the computer to internet, the Microsoft's driver was back immediately. Is there any way just to add the driver's "inf" file?
