This is a modified version of Windows 8.1 Embedded Industry Pro. I call it "Windows 9"
It was designed to bring back the UI from Windows 7, while keeping the kernel improvements from 8.1
You need a license key to activate this operating system.
If you are in college, check if you have a Microsoft Imagine subscription. You can usually get an 8.1 Embedded Industry Pro license key from Microsoft Imagine for free.
Windows 9 is x64 only - this will not work on 32 bit systems.
