Following up on an earlier tweet, Microsoft VP Joe Belfiore followed up with more details about the demise of Windows 10 S as a standalone product. Going forward, he explained, you'll see PCs with either Windows 10 Home, Windows 10 Pro PC or Windows 10 Enterprise with S mode enabled. Additionally, he said if users want to switch out of S mode, they will be able to do so for free, regardless of edition. It should make for a simpler experience than selling the limited version with time-locked upgrade possibilities, and it will start with the next upgrade for Windows 10.
