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.
If affected by a black screen issue after windows update, please visit this page for instructions on how to repair.
Screenshot of the system:

Elias leaned back, his eyes stinging. He’d found the link on an obscure, text-only forum dedicated to "lost media." The uploader claimed it was a mid-90s point-and-click adventure game—a tie-in for the movie that had been scrapped weeks before release. Ping.
He double-clicked. The screen went pitch black. No intro music, no credits. Then, a low-resolution rendering of a suburban house appeared. It looked exactly like the McCallister mansion, but the colors were wrong—desaturated, almost grey. A text box appeared at the bottom: File: HomeAlone-1.0-pc.zip ...
The hum of the CRT monitor was the only sound in Elias’s bedroom at 2:00 AM. On the screen, a progress bar crawled forward with agonizing slowness. Status: 98% (2 minutes remaining) Elias leaned back, his eyes stinging

All pre-installed software/tweaks belong to the companies/people who made it.
Windows 9 might be a registered trademark of Microsoft Corporation, I do not own the term "Windows 9".
