Windows 10 is going to be a cloud based os, they can push NSA spy ware to your computer at will.
Linux is going to be your only option to preserve your privacy soon.
I have heard many cases where Windows 10 makes it hard to install a dual boot system on the same hard drive, I am still planning on this though using a bootable usb stick. They are going to be a life saver for privacy.
For later.
