At its big Windows 10 event today, Microsoft talked about its universal apps, Windows 10 for phones, and a big crazy Surface TV thing. But forget all that. You're gonna be able to stream Xbox One games to any other device in your home that's running Windows 10. That's great and I can't wait to try it.
One advantage Windows 7 has over OS X is that you can stream to your Xbox 360 without the need for third-party software. And though it's still rough around the edges, it mostly functions.
