The whole windows 10 privacy thing is annoying as hell but aside from that, I think windows 10 is a better OS than the windows 7 (yes nobody givesa fuck about windows 8 and windows 8.1. They were the height of Microsoft's shitty OS line. Like WTF were those?
Windows 10 no doubt brought about some performance improvements and made multitasking a tad bit more impressive even if they messed up on the privacy end of things.
Cortana is fucking annoying.
