 Windows 10 is the only platform that enables innovation across this broad family of devices. We were inspired to bring more personal computing to the home and the workplace to enable our customers to do great things. So I'm very excited to announce that for the first year after Windows 10 is available, we will be making available a free upgrade to Windows 10 to all devices running Windows 8.1. We will also be making available a free upgrade to Windows 10 to all devices running Windows Phone 8.1. And last but not least, for the first year after Windows 10 is available, we will be making available a free upgrade to all of our customers still running Windows 7. In fact, with Windows 10, we think of Windows as a service. Are you all ready? Would you like to see a demo? Yes, demo, yeah, alright. So for the first new feature I'm going to show, I need a little help. I know she's here somewhere. Luckily, I can simply summon to the stage. Hey, Cortana. Hey, that's not news yet. Just so you know, I didn't say anything. Yeah, I wasn't suspecting you. Cortana, we're excited to welcome you to the PC. Alright. Hey, Cortana, what do you know about me? Well, I have my notebook, so I know what you know you've let me know, you know? Yes, exactly. We wanted to educate Cortana about PC kinds of things. Hey, Cortana, show me PowerPoint slides about the charity auction. Show me photos from December. Oh, look at this. I'm getting a text right in the middle of my demo. That can't be a coincidence, can it? We're going to be doing work to detect these Skype capable endpoints and automatically move to Skype so that users get the richest possible messaging experience that will communicate with the widest range of people. We are building a wide family of universal apps that will round out the experience on phones, small tablets, and PCs. Cortexel and PowerPoint will be included in Windows 10 on phones and small tablets. We think it's the right time to build a new browser for the modern web which will empower our next generation of Windows users on Windows 10. So today I'm excited to introduce you to a code name, Project Spartan. It has a new look and feel, which you see on the screen, that fits right in with all this family of Windows 10 applications. This article comes out, you can imagine, all of us are simultaneously horrified and kind of happy. I saw this and I said, oh, baby, you know, sometimes you guys don't get it right, but sometimes you do. I can then share that whole page or save that whole page for myself with my markup and now I have a rich canvas for not only expressing my thoughts on the web, but for sharing them with other people as well. We also have a reading list right into the core browsing experience. And of course this will show up on whatever device you have. We'll take the content in your reading list and save it offline. There is one big app experience that I didn't talk about. We'll show you how gaming on Windows 10 will be more social and interactive by bringing together the best of the games you love to play, the people you play with, and the epic moments they create. All of this comes together in the Xbox app on Windows 10. My friends list connects me to all my friends by gamertag wherever they are and wherever I am. Messages keeps me in touch across all Windows 10 devices, Xbox, and the web. And the heartbeat of Xbox Live is the activity feed, which lists all the important gaming moments for me and my friends as I'm able to voice chat and text chat across platform with all of my friends on Xbox Live. I'm here to announce that with Windows 10 we will enable streaming of Xbox One games to any Windows 10 PC or tablet in your home later this year. So we've built a new device to unlock the power of the group in a workplace. I am delighted to introduce you to the Microsoft Surface Hub. This is an 84 inch 4K display with integrated compute. It has built in sensors that actually detected me when I came to the screen. We're dreaming beyond virtual worlds, beyond screens, beyond pixels, and beyond today's digital borders. We're dreaming about holograms mixing your world. Welcome to Windows Holographic. We need it more than just software to make holograms in our world a reality. I'm incredibly excited to introduce to you Microsoft HoloLens. HoloLens is real and this will be available in the Windows 10 timeframe. So we invented a third processor, a holographic processing unit. The HPU gives us the ability to understand where you're looking, to understand your gestures, to understand your voice. It gives us the ability to spatially map the entire world around us and to run without any wires, all while processing terabytes of information from all of these sensors. Are you guys ready to see your very first live holographic experience all running on Windows 10? And look how well in pan Terry is. Play. Nice work Windows 10. I'm a freaking hologram. With HoloStudio anyone can create personalized 3D creations in just minutes. As Lorraine starts building, you notice that everything is as easy as tap, then gaze, then tap again. I think I'll go with a bright yellow. Put some of that here and there. Get this right on top. Oh, too low. Resize. What do you think Alex? I'm getting a good Area 51 vibe. This was made entirely in HoloStudio. What do you think Lorraine? Shall we take it for a spin? Do it. Ironically, our Windows holographic laboratories are located directly below this room. In that very secret space, we've had the great honor to partner with one of the most innovative organizations in history. Our plan is to deploy onsite to mission operations this summer and to be controlling rovers on Mars with this technology in July. These are the kind of magical moments that we live for. These are the experiences that make Windows 10 that more personal computing environment that people are going to love.
