Microsoft Studios and Xbox head Phil Spencer was on hand to show off the feature using Forza Horizon 2.
- Everything we know about Windows 10
"Wouldn't it be great if we could play those games from anywhere in our house, from the couch, out back, in my bedroom?" he asked.
Xbox One-to-Windows streaming lets you play Xbox games on any Windows 10 PC or tablet "in your house,' i.e., on the same Wi-Fi network.
"Today people are playing games on more devices than ever, and with Windows 10 we wanted to focus on those gaming scenarios across device[s]," Spencer said.
He also invited Lionhead Studios' Lauran Carter onstage to demonstrate how DirectX12 enables cross-platform play between Windows 10 and Xbox using the upcoming game Fable Legends.
The two played co-op multiplayer together, with Belfiore on Windows and Carter on Xbox.
Spencer emphasized that Windows 10 gaming is a big focus for the company going forward. In addition it seems many of Microsoft's universal Windows apps will be compatible with Xbox as well.
Windows 10 will launch later this year.
