Windows 10, amazing for some reasons, awful for others
Damn it. Microsoft nearly had it right with Windows 10.
Updates in the Kernel for better performance - YES
Improvements to the audio system meaning leading to very low audio latency when using USB audio devices - YES
Improved DirectX for gamers - YES
Return of the Start menu - YES
I even like the look, though beauty is in the eye of the beholder.
But those privacy issues and their update system needs to die pronto. Hell, I'd be happy to kill the universal apps too for my usage.
