There were reports a while back about support for Windows 7 on Intel
Skylake processors going away. Truthfully, I don't really understand
the implications of that. However, this article,

http://www.channelpro.co.uk/advice/9...-vs-skylake-14

says that Microsoft has changed their minds and will support that
CPU until mid-2018 at least.

Is there a reason for me to avoid building a Windows 7 system based
on a Skylake processor?
