Easily one of the most popular announcements, Microsoft said that Windows 10 will be a free upgrade to anyone using Windows 7 and up for the first year. That's a huge change from the way Windows has been licensed in the past. If you have Windows 7 (which we liked!) or higher, you can upgrade to Windows 10 without paying a dime. Microsoft even confirms that once you're upgraded, you'll get support for the lifetime of the product, so this isn't a trick where you'll have to pay after the first year. Windows Phone 8.1 users will also get a free upgrade, as well.
Good. What's important about the new Windows 10?
Microsoft kicked off the consumer-focused portion of the event by talking about a continuous experience across devices. Often, there's a disruption that occurs when you move from your desktop to your phone, or your phone to your tablet. Microsoft wants to fix this with a feature called Continuum. This allows you to swap between desktop and tablet mode in convertible devices. Microsoft is also moving its mobile and desktop versions of Windows closer together so that apps work similarly across all form factors.
Microsoft also showed off how Windows 10 will behave on phones or tablets, if you use one of those devices. There are new mobile features like replying directly to notifications, a floating keyboard, and voice dictation anywhere you can pull up the keyboard.
But not only that...
Microsoft wants developers to be able to write apps once and run them on everything from Windows desktops to Xbox consoles. The company showed off a bit about how these apps will behave and be distributed. The above is an image of the Calendar app that was written for the Universal Apps platform and automatically adapts to different interfaces.
Microsoft showed off the Ribbon interface in Word as it appears in Windows phone, described as a "nearly no compromises" experience. The upside is that if you get used to a menu on one device, all the same functions should be in roughly the same place in mobile versions of the app with a slightly different layout. This is very similar to the way Android handles phone-to-tablet conversions, which dynamically adjust to different screen sizes. A welcome (And long awaited) approach.
But you guys always talk about GAMES!!!
I KNOW! And Win10 is going to hit the Xbox One!
Microsoft took a step in Steam's general direction with a brand new Xbox app for Windows 10. The app will come pre-loaded on all Windows 10 devices. For Xbox Live users, you can chat and voice chat with everyone on your friends list, see all of your games in the app, view screenshots and videos from players and so on.
The Xbox app goes even further by allowing you to record your own videos for any Windows app. Including Steam games. The company demoed the Xbox app recording a gameplay video of Sid Meier's Civilization—a version of the game that is old enough that it hasn't been updated for Windows 10 at all—with the screen recording feature. It even works with games run from Steam, so it's nice to see the service playing nicely with other gaming platforms.
Gamers have plenty of reasons to enjoy Windows 10, as well. The biggest news is that Microsoft will allow Xbox One users to stream their games to the PC, much like Steam's in-home streaming works, just in reverse. The games will run on your console and stream across your home Wi-Fi to your desktop, so you can play it in the best interface for your play style.
