Hello guys,i'd like to ask if it would worth to upgrade from windows 8.1 to windows 10.Last year I've heard that it has severe privacy issues and it could serve as a great way for hackers to "sneak" into your personal computer.Also,i've heard that Microsoft can delete pirated content without your desire.I would like to know if windows 10 it's just better than windows 8.1 in terms of performance,if these 2 operating systems have similar security vulnerabilities,and if those privacy problems can be solved in a way or another in order to assure myself that I'm safe on my own terminal.
