Windows 10 hits July 29, delivering Xbox One to PC game streaming

After the beta testing of four million people, Microsoft today announced that Windows 10 will hit July 29.

The operating system will be a free upgrade for customers running Windows 7 or 8.1. If you purchase a new Windows 8.1 device between now and then, the Windows 10 upgrade will be available to you, and many retail stores will upgrade your new device for you, according to the post on the official Windows blog.

You can reserve your free Windows 10 upgrade now through a reservation process in your computer's system tray, though it's unclear what that does for you.

Windows 10 brings with it the advent of universal apps, which helps with cross-play between PC and Xbox One, the possibility of cross-purchase of games and the ability to streaming games from one platform to the other.

Here's Microsoft's breakdown of Windows 10 Xbox Live and the integrated Xbox App:

Xbox Live and the integrated Xbox App bring new game experiences to Windows 10. Xbox on Windows 10 brings the expansive Xbox Live gaming network to both Windows 10 PCs and tablets. Communicate with your friends on Windows 10 PCs and Xbox One — while playing any PC game. You can capture, edit and share your greatest gaming moments with Game DVR, and play new games with friends across devices. You can play games on your PC, streamed directly from your Xbox One console to your Windows 10 tablets or PCs, within your home. Games developed for DirectX 12 in Windows 10 will see improvements in speed, efficiency and graphics capability.

Microsoft detailed what the new operating system would mean to gamers and consumers at an event on its Redmond Campus earlier this year.
