Howdy, folks, and greetings from scenic Redmond, Washington, where Microsoft is about to give us a lot more information about its next-gen OS, Windows 10. Sure, we may have already gotten a peak at the new and improved Start Menu, but there are still so many unanswered questions. What will it be like to use Cortana from the desktop? How will those "universal" apps look across different devices? And where does Xbox fit in, exactly? Follow our liveblog starting at 9AM PT / 12PM ET, where we'll be reporting all the news, as it breaks. And who knows, maybe you'll even get to download a preview for yourself once it's all over. Only one way to find out, though: stay tuned!
