If you expected Zen to support anything before Windows 10, bad news: http://digiworthy.com/2017/02/09/amd-ryz...windows-7/

Recently, a report from ComputerBase emerged online which indicated AMD’s upcoming Ryzen processors would support Windows 7, despite Microsoft having already said that the chip would only be supported under the latest Windows 10. Today, AMD clarified on the issue and confirmed it won’t ship Ryzen drivers for Windows 7.

“To achieve the highest confidence in the performance of our AMD Ryzen desktop processors (formerly code-named ‘Summit Ridge’), AMD validated them across two different OS generations, Windows 7 and 10,” AMD said in a statement. “However, only support and drivers for Windows 10 will be provided in AMD Ryzen desktop processor production parts.”
