I'm looking at my brand new Skylake computer screen after having just upgraded to Windows 10 last night. I haven't done anything to it besides install my Asus drivers. It's currently a completely virgin Windows 10 installation.
How do I make WIndows 10 as private as possible after upgrading?
You cant, it will always have telemetry and send your info to Microsoft.
Install Spybot Anti-Beacon
