As I mentioned before, I invested more than 2300$ in order to get the best experience.
Look here what happend during the upgrade from Windows 7 Ultimate to Windows 10 Pro:
The installation resulted in a major crash, despite the fact that I know for sure that all my drivers were 100% correct and updated before initiating the installation.
I had to hard reset the laptop which is really bad on a SSD.
Dell - This is really bad customer service.
