>installling Windows 10
Who would unironically install a botnet that automatically upgrades itself without telling you what's in it first like on previous versions?
I keep hearing people complain about W10 automatically restarting cause you can't, or rather it is pretty difficult for non-savvy people, disable updates, but I honestly feel they deserve it for choosing to infect their PC with W10.
The only real reason to use W10 if it came with your computer/laptop pre-installed, but even then you could just buy OS discs of older versions.
Personally speaking, I use XP cause it's the best OS. All future OSs are dumbed downed versions created for the lowest common denominator of people.
